Aluminum Oxide Grit Uses

Catalyst and catalyst carrier: Alpha Aluminum Oxide Grit has a high surface area and stability and is often used as a catalyst in petroleum refining and petrochemical processes, such as catalytic cracking, hydrotreating, etc. At the same time, it is also an effective carrier for many chemical reaction catalysts and can load other active substances.

Advanced ceramics: Due to its high melting point (about 2050°C), high strength and excellent electrical insulation, alumina is the main raw material for manufacturing high-performance ceramics, such as electronic ceramics, wear-resistant ceramics, bioceramics (such as artificial joints) and High temperature resistant ceramic parts (such as jet engine parts).

Abrasives and polishing materials: Because of its hardness, Aluminum Oxide Grit abrasives are second only to diamond and cubic boron nitride. They are widely used in the manufacture of grinding tools such as grinding wheels, sandpaper, and emery cloths, as well as precision polishing materials for the processing of metal, glass, and semiconductor materials. and surface treatment.

Refractory materials: Due to its good high temperature resistance and chemical stability, alumina is an important component in the manufacture of refractory bricks, castables and refractory fibers, and is used for the lining of high-temperature furnaces, steelmaking furnaces, glass furnaces and other equipment.

Electronic industry: High-purity α-type alumina is a material used in the production of integrated circuit substrates. Its excellent dielectric properties and thermal stability ensure the high performance and long life of electronic devices.

Adsorbent and dehydrating agent: γ-type alumina (activated alumina) has a highly porous structure and large specific surface area, and can be used as a gas desiccant, a deacidifying agent for oil purification, and an adsorbent for air purification.

Optical materials: High-quality aluminum oxide single crystals, such as ruby and sapphire, are used in laser components, watch crystals, optical windows and lenses due to their excellent optical transparency and hardness.

Aerospace: Aluminum oxide composites are used in the manufacture of structural components for aircraft and spacecraft due to their lightweight, high strength and high temperature resistance properties.

Water treatment: In the field of water treatment, alumina can be used to remove fluoride and phosphate from water and purify water quality.

Prominent Applications of Aluminum Oxide in Makeup

Thickeners and suspending agents: Aluminum Oxide Grit has good oil and water absorption capabilities and can be used as a thickener in cosmetic formulas to help adjust the viscosity and stability of products (such as foundation, sunscreen, concealer) and prevent component separation , making the product texture easier to apply and longer-lasting.

Scrub: Fine aluminum oxide particles are often used as scrub particles in physical exfoliation products because of their moderate hardness and smooth surface. They can gently remove dead skin cells on the skin surface, promote metabolism, and improve skin gloss and touch. .

Absorbent: Aluminum oxide can effectively absorb excess oil on the skin surface and help control facial shine. Therefore, it is used in cosmetics such as oil-control powder and loose powder. It can provide users with a matte effect and extend the durability of makeup.

Covering agent: In some foundation and concealer products, aluminum oxide can provide a certain degree of covering effect due to its fine powder properties, helping to cover skin imperfections such as stains and acne scars.
