1.Refractory silica brick is made from Wutai Mountain silica and Tiemen silica: the characteristics of Wutai Mountain silica is uniform in iron content distribution and fast in transformation, belonging to cementation silica. The Tiemen silica, belonging to crystal silica, is high in purity, stable in chemical composition and slow in transformation. Combined with the two kinds of silica, the products are not only fast in transformation, but high in refractoriness under load and Tlase ka creep. .
