Mullite ceramics


Mullite ceramics has high intensity as a alumina ceramic in room temperature. Also it is strong to high temperature condition, and it has small CTE.

Strong Point

-High thermal shock resistance
-High wear and abrasion resistance
-Manufacturing cost is low


・Heat resistant parts
・Setter for firing process
・Material for high-temperature service
