Refractory Silicon carbide kiln shelves for industrial high temperature furnace
1. Introduction
Silicon carbide kiln shelf is combined with high purity silicon carbide and ultra fines. Shaped by vibration, made by high sintering. The SiC platesare oxide bonded silicon carbide based products, which are used in Kiln Furniture. It is featured with high bending strength at elevated temperature, good abrasion resistance, Resistance to thermal shock, high thermal conductivity and offers a good life.
Refractory high temperature silicon carbide kiln shelf is widely used to fire sanitary ceramic , daily ceramic , porcelain , and pottery.It has high strength and good quality.Commonly we coat alumina on one side, it can protect your product.In order to make sure no pollution to your products.
