Product Description
Product Introduction
Alumina Oxide Powder
Our calcined alumina powder is a premium-grade ceramic material produced through precise high-temperature calcination, ensuring exceptional purity, hardness, and thermal stability. With an Al2O3 content of ≥99.5%, it meets the stringent requirements of critical industries. The powder features customizable particle size distribution (D50 from 1 to 10 μm), optimized BET surface area (5–15 m²/g), and a Mohs hardness of 9 for superior wear resistance. It withstands temperatures up to 2000°C, making it ideal for refractory applications. Chemically inert against acids, alkalis, and solvents, it ensures reliable performance in harsh environments. Its low thermal expansion coefficient guarantees dimensional stability under extreme temperature cycling. Widely used in advanced ceramics, abrasives, catalyst carriers, electronic substrates, thermal spray coatings, and aerospace components.
