Refractory sic slab


Refractory sic slab introduction

Oxide Bonded Silicon Carbide(OSiC), also called Refractory sic slab used for firing general chinaware and ceramic product (temperature below 1,450°C), is made by SiC bonded by Silicon Oxide (Si2O3), and technically called "Oxide Bonded Silicon Carbide".
This Refractory sic slab has very high thermal conductivity (almost 10 times higher than mullite refractory) and high radiation rate of Long-wavelength infrared that bring very high heat efficiency toward products.
In terms of cost performance for firing general chinaware and ceramic products, this Refractory sic slab is the most valuable and suitable refractory.
