product name
A-PU99 (Alumina99% porous ceramics) A-PU98 (Alumina98% porous ceramics) A-PU96 (Alumina96% porous ceramics) A-PU93 (Alumina93% porous ceramics) A-PU85 (Alumina85% porous ceramics) A-PU69 (Mullite porous ceramics) M-PU99 (magnesia99％ porous ceramics) M-PU98 (magnesia98％ porous ceramics) Z-PUC-F (zirconia porous ceramics) S-PU08S (silica porous ceramics) Porous ceramics (alumina, mullite, magnesia, zirconia, silica) Rammer molded product
Characteristic
Porous ceramics are ceramics that have countless pores inside. Ceramics have low thermal conductivity due to their porous nature, are lighter than metals, and have high heat resistance and thermal shock resistance. Maruwai Yano Ceramic Works can provide large-scale porous ceramic production. Maximum production size Φ720×1260H (for porous alumina crucible)
Shape/Application
Crucible and pod for vacuum melting Thermal shock resistant material products, insulation parts, melting furnace parts Tamman tube/sleeve/tube/pipe Setter/heart plate fireproof nozzle
