In physico -properties, liner expansion coefficient is mainly considered. As for chemico-properties, basic index, oxygen content and com- position of slag are studied. An equation can be obtained by using ceramics and mineralography which may predict detachability of basic type SSFCE. Other valuable conclusions are also drawn.展开更多
