1·Through wet processing technology, aluminium salts and alumina can be produced from the kaolinite, and the residues from above process can be used to prepare calcium silicate, white carbon, and etc.
如采用湿法处理工艺可生产铝盐及氧化铝，并可利用生产铝盐制品的残渣生产硅酸钠、白炭黑等产品，高岭土还可加碱合成多种沸石产品。
2·Thus it is affirmed that the combination of the two materials are matchable and that the strength and fracture toughness of alumina-silicate ceramic matrix have been greatly improved.
本课题所试制的铝硅酸盐陶瓷基体的强度和断裂韧性有较大的提高。
