FIXTURE FOR FIRING CERMIC ELECTRONICS PARTS

摘要

PROBLEM TO BE SOLVED: To provide a fixture for firing a ceramic electronics parts having an improved durability by suppressing a reaction with a body to be fired. SOLUTION: A three layered structure is formed by one body forming. The structure has a base material consists of a refractory raw material of 85 wt.% silicon carbide and its both faces (inside and outside) consist of zirconia (yttoria stabilized zirconia or carcia stabilized zirconia) whose zirconia content is not less than 80 wt.%. The ratio of the thickness of the base material to both faces being 1:1 to 4:1 and the total thickness of which is not less than 5 mm and not more than 30 mm.
