Molecular formula :
CAS :
nature : adobe high temperature densification process and the phenomenon known. With increasing temperature, ceramic green body surface area has, the higher surface energy powder, sought to reduce the surface energy of the direction of change, constant material movements, grain boundary followed mobile, stomatal gradually eliminated, the shrinkage, adobe have become dense strength of the porcelain body. The driving force for sintering surface energy. Sintering can be divided into a liquid phase sintering and the participation of pure solid-phase sintering two. Sintering process of ceramic production will be very important significance. In order to lower the sintering temperature, expanded firing range, usually include some additives for flux, forming a small amount of liquid for sintering. As for adding a small amount of silica ceramic barium titanate; Also add a small amount of magnesium, calcium oxide, silica for alumina ceramic sintering.
