ZX Carbon hot SiC paste

Applications

ZX hot SiC paste is developed for maintenance of the Tap-hole Are to avid Oxidization.

Specification：
The permeability of the final product is very low, 0.1 nP.

At 900-1000°C the paste gives a SiC/C material with high density and excellent mechanical strength.

At 1400-1500°C the paste converts to 100% SiC.
