文摘The reaction of sillimanite with alumina at temperatures 1650℃ an 1750℃ has been investigated.The results have shown that,in the laboratory test conditions,the higher the alumina content,the lower will be the amounts of glass-phse of the fired body and the higher will be the formation of mullite .In the present tests,however,the reaction in concern has not been completed,the reaction in concern has not been completed.Some uncombined residual alumina still exist in the form of corundum.
