High quality silica brick for glass kiln

We are one of the professional manufacturers of high quality silica bricks for glass kiln. Due to the multi-stage high-purity quartz ratio, the physical and chemical indicators of our products have reached the advanced level of similar products in the same industry. It is characterized by high starting temperature of load softening, long-term high temperature and no deformation, and has been used in glass melting furnaces for a long time. At the same time, the products can also be used in open hearth regenerators, high temperature hot air furnaces and silicic acid industrial furnaces.
