The chemical composition of the product is stable, the SiO content is high, the impurity content is low, the phosphorus quartz phase is the main crystal phase, and the quartz is completely converted.


Various types of silicon bricks or high-quality silicon bricks for carbon calciners with an annual output of 400000 and 600000 tons of carbon


Carbon furnace wall parts if the use of high thermal conductivity, high resistance to erosion silica brick, can greatly improve its thermal conductivity, corrosion resistance.


Good load resistance at high temperature, stable volume at high temperature for a long time, low thermal expansion rate, low residual quartz content (<1.0%)
