99.99% high purity composite alumina ceramic powder
Simple Introduction for High Pure Aluminum Ceramic Oxide Powder:
The high purity composite ceramic aluminum oxide powder produced by our professional factory is a ideal choice because of its high purity, low-temperature sintering, the tiny uniform microstructure as well as the sintering density. The microstructure of ceramic powder has become  sitallization and uniformity, meanwhile the bending strength of alumina ceramic materials has been enhance strongly on account of its low-temperature sintering.
Usage fields
HCAF-305 aluminum oxide ceramic powder is the basic powder of this kind products, which is put in the process of Low temperature phase inversion, edulcoration, dispersal, desiccation, homogeneity. It applies to the slip casting process manufacturing large scale, intricately shaped, thin-walled alumina ceramic material.
Due to the features of high purity, small and uniform particle size, spheroidal, HCAL-305 powder especially is used for making the Lithium battery ceramic diaphragm,so that it can improve effectively the mechanical capacity, resistance to elevated temperatures and safety performance of the battery.
HCAZ-305 composite aluminum ceramic powder is based on HCAF-305. The product process is that we put micromagnesium oxide and surface modifiers in the HCAF-305, and then puting them into the spray granulation process. It applies to dry pressing and isostatic pressing Alumina ceramic material.
