Alumina Powder

Alumina powder is an inorganic powder material with high-purity alumina as its main component. It is a widely used basic raw material in the chemical, ceramic, electronics, new energy, and fine processing industries. This category covers various types of alumina powder products, including activated alumina powder, γ-alumina powder, high-purity alumina powder, low-sodium alumina powder, and alumina powder for special purposes, which can meet different process conditions and performance requirements.

In the fields of catalysis and adsorption, activated alumina powder and γ-phase alumina powder are often used as catalyst supports or adsorbent precursor materials. They have high specific surface area and controllable pore structure, making them suitable for preparing catalyst supports, desiccants, and gas purification adsorption materials. They exhibit good reaction efficiency and stability in oil refining, chemical synthesis, and environmental treatment processes.

In the high-end materials and electronics industries, high-purity alumina powder is widely used in advanced ceramics, electronic substrates, LED packaging, and semiconductor-related materials. Its high purity and low impurity content give it excellent insulation properties, thermal stability, and consistency, making it suitable for applications with stringent material performance requirements. Meanwhile, low-sodium alumina powder, by controlling its sodium content, effectively improves the reliability of materials in high-temperature or electrical performance applications.

In the fields of grinding, polishing, and wear-resistant materials, abrasive-grade alumina powder and polishing alumina powder, with their high hardness and stable particle size distribution, are used in surface treatment processes for metals, glass, ceramics, and optical components, contributing to fine machining and improved surface quality.

Furthermore, alumina powder can also be used as a functional filler in coatings, plastics, and composite material systems to enhance the mechanical strength, heat resistance, and wear resistance of products. This product category supports various particle sizes, purities, and crystal phases, and can be customized to specific application needs, helping customers select alumina powder solutions better suited to their operating conditions.
