The jig and its production mannered (normal calcination) null mean diameter for heatproof bombardment Characteristic alumina

摘要

PPROBLEM TO BE SOLVED: To provide a burning tool free from silica components made of an alumina-zirconia, which has excellent thermal shock resistance, exhibits durability to repeated heat cycles and is suitable for firing, especially, electronic components, and to provide the tool for electronic components, which is obtained by forming a zirconia layer on the surface of the alumina-zirconia core excellent in thermal shock resistance and is prevented from reacting with alumina and is composed of silica free base materials and optimally used for burning a MLCC (multilayer ceramic capacitor). PSOLUTION: The alumina-zirconia burning tool is composed of coarse particles and fine particles. In the alumina-zirconia burning tool, particles of zirconia are finely dispersed in alumina substance for binding alumina coarse particles. PCOPYRIGHT: (C)2003,JPO
