Refractory soil ingredients
Refractory soils are mostly composed of halosite, kaolinite,monothermite, hydrocele and quartz, feldspar impurities. Due to the variety of refractory soils, we should consider some points when selecting and purchasing refractory soils needed for manufacturing the products. If the impurities of refractory soils are from bauxite minerals, this will increase the the amount of alumina and thus increases the igneousness of the soil. If the impurities are from materials such as iron and titanium compounds, this will decrease the dough point of the part made from that given refractory soil.
