摘　　要：可加工氟金云母陶瓷很难烧结致密;真空状态下,作为焊接模具在900℃左右常常出现鼓泡、真空放气现象,严重影响焊接制品的质量;在原有实验基础上,通过优化工艺,制备出高致密的可加工陶瓷,解决了鼓泡、真空放气问题。Sintering of machinablefluorophlogopite ceramics is pressure, and often appear bubbling and outgassing problem under ramics with high density are prepared with process optimization, an sing are solved. difficult to full density state without vacuum state in 900℃. Machinable and the problems of bubbling and outgassing are solved.

关 键 词：可加工陶瓷 鼓泡 真空放气 氟金云母
