Fused silica panel is the heat resistance material which has replaced the traditional metal radition board. It has good strength,low conductivity,no deformation under high temperature,heat resistance parameter,which is widely used in industrial furnace,as a result will protect the temperature via heat equally spread and no heat loss.
