Japan's Sumitomo Chemical successfully developed a new production technology for ultra-fine α-alumina. The mass production will be started this September with its recently established manufacturing capabilities at its Ehime Works.
Alumina materials made by calcining aluminum hydroxide at high temperatures, with a purity level of 99.99% or more are called ultrahigh purity alumina. They have characteristics of homogeneous ultra-fine particles with a particle size of 150 nm (0.15 μm) or smaller.
The mass-produced new products are sold as NXA series products. This series of products are ultra-fine grade α-alumina products mainly used in industrial products.
