摘要

PURPOSE:To industrially, easily obtain the ceramic sintered compact little in mechanical strength drop at an elevated temperature of 1400 deg.C, hardly developing deflection due to load application and good in moldability. CONSTITUTION:The objective mullite ceramic material powder, having a specific surface area of 3-10m2/g and mullite crystallite diameter of =200nm and comprising (1) 35-75 pts.wt. of spherical powder =5mum in particle diameter and (2) 65-25 pts.wt. of powder =2mum in particle diameter. The objective sintered compact can be obtained by molding the above powder followed by sintering at =1600 deg.C.
