Πυριτικά ορυκτά αλουμίνας

Το πυριτικό αργίλιο μπορεί να βρεθεί στη φύση ως ανδαλουσίτης, κυανίτης και σιλιμανίτης - κάθε ορυκτό διαθέτει τη δική του ξεχωριστή κρυσταλλική δομή.

Natural and synthetic zeolites are crystalline aluminosilicates containing more than one Si/Al ratio, boasting large cavities for hosting charge-balancing cations in “extraframework voids”.

Kaolin

Kaolin, or soft white clay found naturally, has many applications and uses in nature and society. An aluminosilicate substance composed of silica and aluminum atoms, Kaolin is mined globally for use in paper products, ceramics, paints, rubber tires and cosmetics as well as being an ingredient used as medicine against diarrhea.

Clay can also be extremely beneficial to skin health and has long been used as a natural facial cleanser. It has long been utilized as an excellent natural cleansing product, effectively clearing away dirt and excess oil from pores to prevent blackheads and breakouts while its antibacterial properties help eliminate infections while soothing inflammation.

There are various varieties of kaolin clay, each differing in terms of plasticity, crystal and surface chemistry, particle size and shape, flow characteristics, permeability and workability. While some types have plastic bodies for easy manipulation while others possess casting qualities which make casting difficult; also their color can range from pink from iron oxide deposits to greenish hues due to decomposing plant matter.

Kaolin is a widely used component in concrete mixtures as it adds bright white coloring without altering their chemical or physical properties. Kaolin makes an excellent construction material additive as it helps increase strength and durability of final products.

Kaolin is also widely used to produce fiberglass insulation due to its low thermal conductivity, which increases insulation value of finished products.

Kaolin is widely utilized as an agricultural crop protectant. It creates an effective protective barrier film against insects, mites and diseases. Furthermore, kaolin’s antifungal properties make it suitable for seed coating applications as it effectively reduces mold growth while being less toxic than traditional pesticides.

Sillimanite

Sillimanite, also known as fibrolite by Count de Bournon of southern India in 1802, and as sillimanite by Bowen in Chester, Connecticut 1824 was one of the more frequently occurring minerals within the Aluminosilicate Group of Aluminosilicate minerals. It’s composed of polymorphs of both Kyanite and Andalusite with chemical formula Al2SiO5. Initially identified by Bowen (1824) from Chester Connecticut samples collected as “fibrolite,” it occurs as fibrous aggregates embedded within gneiss/schist or pegmatites with isolated prismatic crystals of any size rare compared to brown chatoyant gemstones found as Brown Chatoyant gem sands such as Sri Lanka Thailand or Burma.

Sillimanite is one of the key raw materials for high alumina refractories used widely across industries like Iron & Steel, Petrochemical, Electrical, Cement and Zinc production. With an extreme hardness on Mohs scale of 5, Sillimanite has incredible chemical resistance; when heated above 1545 degC it converts to Mullite with any excess silica being converted to Glass Crystoballite Tridymite etc.

As one of the more frequently occurring minerals in metamorphic rocks, muscovite is often present. It forms via regional metamorphism of clay rocks (gneiss) from biotite or andalusite sources, polymorphic transformation of disthene or dehydration reactions between muscovite and staurotide minerals, and dehydration reactions between muscovite and staurotide minerals. Muscovite serves as an indicator mineral for high temperatures and variable pressure conditions and its presence indicates such conditions in high-grade metamorphic rocks indicating high temperature and variable pressure conditions.

Metamorphic rock deposits tend to contain quartz crystals which form prismatic shapes with long prismatic crystals arranged along their long axis, as well as fibrous masses with occasional acicular projections and excellent parallel cleavage parallel to its long axis. Furthermore, its crystal structure has an orthorhombic arrangement with high silica content, consisting of both octahedra and tetrahedra alternatingly arranged.

Spiritually, sillimanite is an uplifting stone that provides personal stability and security. It encourages deepened connections to higher energies while encouraging self-discovery and aligns the chakras, increasing intuition and inner wisdom. Furthermore, it makes an excellent stone for meditation as its focus increases while protecting against negative energies or distractions.

sillimanite enhances both shrewdness and insight, leading to smarter business decisions. Additionally, sillimanite can increase productivity so you get more done faster – ideal if you are leading others or in an authoritative role. If so, sillimanite can provide your team with the skills needed for its success.

Kyanite

Kyanite (pronounced KAY-nite) is an exquisite gem variety containing shades of blue, green, orange and black. This crystal has numerous uses: clear communication; opening up the third eye; dream recall/past life exploration/connection to spirit guides/ancestors and relaxation. Kyanite’s soothing energy also helps relieve tension/stress while aiding relaxation.

Kyanite derives its name from the Greek word kuanos, which translates to blue. This coloration refers to its most prevalent hue; however it also appears in yellow, purple and white hues. Kyanite’s striking appearance has made it a sought-after stone in jewelry designs; often paired with Lapis Lazuli for centuries due to both its timeless beauty and spiritual significance.

This stunning gem can be found all around the world, with notable deposits in Brazil, Switzerland, Russia, India, Kenya, Nepal and Serbia. Each geographical area provides its own distinctive physical and energetic characteristics that allow collectors and healers to choose the appropriate piece.

Kyanite can be found in non-gem form as an important material used in manufacturing ceramics and abrasives, and used by geologists to track metamorphic zones. Furthermore, its high temperature sinterability makes it a perfect candidate for use as part of refractory goods and molds.

Kyanite gemstones can be identified by their transparency and characteristic rutile needle inclusions, which make the gemstone easily recognizable. Crystals are generally cut, polished and then faceted for gem use. Kyanite is relatively soft gemstone that should be handled carefully – for best results wear it alongside jewelry that protects it from scratches and impacts such as earrings, pendants or bracelets and charms.

Kyanite can be placed in a water bowl or near running water to reenergize its energy. Placing it under the light of a full moon can further strengthen its power. You could even place some Kyanite on a windowsill overnight so it can absorb some of this powerful moon energy – this will help balance chakras and promote clarity of thought while relieving tension, alleviating stress, and encouraging relaxation.

Magnesium Aluminum Silicate

This ingredient is a fine silicate extract derived from naturally occurring clay minerals that is commonly found in makeup and skin care products. It acts as both a thickening agent and texture enhancer, helping to increase spreadability while imparting opacity for an even distribution of pigments across formulas. Common uses for this ingredient are foundations and concealers – though you might also come across it shampoo/conditioner sets, body washes or moisturizers!

Magnesium aluminum silicate (MAS) is an inoffensive white or creamy powder with no discernible odor or taste, used as an absorbent material that has great water and oil-absorbing capabilities. It dissolves easily in water or alcohol solutions, and serves both suspending/disintegrating agents as well as cream/ointment lubricants.

In skincare, bentonite clay helps hydrate and calm skin by reducing redness and irritation as well as stimulating cell regeneration. Furthermore, its absorbency capabilities make it an attractive ingredient choice in cleansing products and masks; its safety for use by most individuals also makes it a good non-comedogenic ingredient that won’t block pores.

Natural and synthetic forms of gum arabic can be found depending on a manufacturer’s needs. It often works well when combined with thickening agents such as xanthan gum or cellulose gum for additional thickening, as well as in formulations to stabilize both oil-in-water and water-in-oil emulsions.

Synthetic magnesium aluminum silicate shares many of the same properties with its natural counterpart, yet is more readily available at a lower cost and with consistent quality. It is often combined with other ingredients like talc, calcium carbonate and sodium bicarbonate to produce finely milled white powder without odor or flavor.

Pharmaceutical industries widely utilize it as an absorbent, anticaking agent, binder for tablets and capsules, opacifier, slip modifier, and viscosity-increasing agent. Furthermore, it possesses antiacid activity to protect stomach from hyperacidity while simultaneously inhibiting excessive gastric acid secretion by controlling pepsin activity and neutralizing excess gastric acidity levels. Furthermore, its antiulcer activity provides effective protection.
