Nishimura Original ceramics (Zirconcordierite)

【zircon cordierite(N-32)】

-Zircon(ZrO2・SiO2)is one of the material which has good thermal shock resistance.
-We mixed this zircon with cordierite. This ceramics advantages are better resistance of thermal shock and stabler firing shrinkage.

Strong Point

-High thermal shock resistance
-Low thermal expansion
-Smooth surface
-self grazed body
-Stain resistance
-Milky white color

Usefulness

-Heat resisting parts
-parts which needs low thermal expansion
-Halogen light part
