摘　　要：The molecular formular of celsian is Bao·Al 2O 3·2SiO 2 Its smelting point is 1 770℃ and thermal expansion coeffcient is lower. According to the literature reports, the monoclinic celsian therrnal expansion coefficient of ceramic are 2.7×10 -6 /℃(20～1 000℃),therefore, the celsian has the good urgent cold resistant and heat resisting. Taking the monoclinic celsian as the basic material of ceramic, its applied prospects are very extensive. Celsian deposits are quite fewer dispersed in the nature. We make use of kaolin and baryte of Guizhou as raw material and carry out the experimental research on artificial synthetic celsian, and explored the influence factors of all kinds for synthetic celsian.The molecular formular of celsian is Bao·Al 2O 3·2SiO 2 Its smelting point is 1 770℃ and thermal expansion coeffcient is lower.
