The products of this series have relatively large primary crystal sizes,steady performances.good formability,small shrinkage ratios and wide applicable ranges,and are especially applicable to hot pressure casting and slip casting series.Moreover,it could be applied to various high temperature-resistant ceramic parts (spark plug and others),wear-resistant ceramic parts (lining of mortar pump and plunger pump,impeller and grinding dielectric ball etc),electronic substrate,electronic vacuum tube and others.
