Quick Details
Specifications
Features:
This series is a new ultrafine powder. Its crystal size is even smaller (0.5~1um). It can be easily ground to about 1um average sizes of micro powder. It has a narrow range of powder particle size distribution and a good dispersion.
Applications:
It can be used in knife tools, precision alumina ceramics and all kinds of ceramic tools produced in the way of isostatic pressing method. It can also be used in mirror polishing.
