Quality Silica bricks are the key refractories for high temperature area of industrial kilns and furnaces including coke oven, hot blast stove, glass tank etc.
Our high quality silica bricks enjoy the main characteristic of high dense( good for thermal conductivity),high RUL and high tridymite content, low true density, low expansion, low creep and low residual quartz, accurate size tolerance, purity colors and luster forming good appearance.
