METHOD FOR PRODUCING ALUMINUM TITANATE- MULLITE CERAMICS WITH LOW THERMAL EXPANSION BEHAVIOR

摘要

The invention is a small thermal expansion of aluminum titanate-mullite ceramic manufacturing relates to (Al ₂ TiO ₅ -Mullite).; Ceramic manufacturing method of the present invention as mol%, and then pulverized by mixing from 3 to 7% of Fe ₂ O ₃ was added to the 40 ~ 60% Al ₂ O ₃ and TiO ₂ being 60 to 40%, molded, and sintered aluminum titanate was obtained the carbonate powder, and then mixed and ground to 40 to 60% of ZrO ₂ and TiO ₂ being 60 to 40%, molded and sintered to obtain a mullite powder, the mixture since the aluminum titanate and mullite powders with each other and that for producing a mullite ceramic to the technical aspect - after molding, by sintering aluminum titanate.
