Application
Alpha-phase alumina nanopowder with a purity of 99.9% finds its major applications in the production of advanced ceramics, nanocomposites, and as a catalyst support material. The high surface area and excellent dispersibility of alpha-phase alumina nanoparticles make them ideal as a reinforcing agent in nanocomposites, where they improve the mechanical, thermal, and electrical properties of the composite material. In advanced ceramics, the fine particle size of alpha-phase alumina nanopowder makes it a suitable material for use where a high degree of homogeneity is required. Alpha-phase alumina nanopowder is also used as a support material for catalysts due to its high surface area and excellent thermal stability. It is particularly attractive for catalytic applications due to its low acidity and high chemical inertness.
