Functions and uses of alumina powder

Alumina powder has many functions and a wide range of applications, mainly including the following aspects:

Paint industry: Alumina powder is used as a filler in paint to significantly improve the wear resistance, corrosion resistance and hiding power of the coating. Its high hardness and good gloss make the paint more durable and beautiful. ‌

Plastic industry: Alumina powder, as a modifier of plastic, can improve the hardness and heat resistance of plastic and is widely used in various plastic products. ‌

Ceramic industry: In ceramic products, alumina powder is used to improve the hardness and wear resistance of ceramics, and is often used to manufacture high-end tiles and ceramic knives. ‌

Electronic industry: Due to its excellent insulation properties and high temperature stability, alumina powder is widely used in the production of electronic components, such as circuit boards, electronic packaging materials and radiators. ‌

Automobile manufacturing: In automobile manufacturing, alumina powder is used to manufacture lightweight engine components and brake systems to improve the performance and fuel efficiency of automobiles.

‌Aerospace‌: Due to its high strength and wear resistance, alumina powder is used in the aerospace field to manufacture high-temperature structural parts and engine components.

‌Biomedical‌: In the biomedical field, alumina powder is used to manufacture artificial joints and dental implants, taking advantage of its high hardness and wear resistance.

‌Construction Industry‌: In construction, alumina powder is used as an admixture for concrete to improve the compressive strength and durability of concrete. ‌

‌Rubber Industry‌: In the rubber industry, alumina powder is used as a reinforcing agent and activator to improve the wear resistance and anti-aging properties of rubber.

‌Catalyst Carrier‌: Due to its high specific surface area, alumina powder is often used as a carrier for catalysts to improve the performance of catalysts.
