The phase composition of silica brick is mainly tridymite and cristobalite.
It is highly appreciated by our clients for its accurate size, good thermal conductivity, and high refractoriness under load, strong ability of resistance to acidic etching, low creep and low expansion.
Our cases show that the service life of the silica brick on carbon furnace has been used for more than 20 years (still in the usage for production).
“Cunse” brand silica brick for carbon furnace is gradually become the first choice by carbon furnace enterprises at home and abroad.
