Description:

DCP-5 and DCP-4 are alpha aluminas with controlled particle size distribution after milling, separating coarse calcined alumina. DCP-3, DCP-2 and DCP-05 are produced by grinding calcined alumina to the primary crystal size.
These are narrowly distributed alumina powders, which enable optimal filling. These items improve the mechanical strength, chemical resistance and thermal stability of refractory, tile and ceramics.
