Title:
RECYCLABLE CERAMIC
Document Type and Number:
Japanese Patent JP3312436
Kind Code:
B2
Abstract:
PURPOSE: To provide a recyclable ceramic capable of being easily crushed and recycled by adding a specific dispersing phase to a matrix phase using a non- oxide ceramic, sintering the mixture, heating the sintered product, and subsequently cooling the heated sintered product.
CONSTITUTION: A matrix layer using a non-oxide ceramic is added with ≥30wt.% of a dispersing agent having a difference of ≥3×10-6/°C from the thermal expansion coefficients of the matrix phase and are compounded with each other, and mixed under a wet condition. The produced raw material is dried, shattered classified and subsequently preliminarily molded. The molded product is sintered, heated and subsequently cooled to crush into a powdery state.
