What is inside the red quartz sandstone. So red?
Quartz sandstoneQuartz sandstone (quartz sandstone, quartzite, quartz sand, quartz vein). Glass and metallurgical auxiliary raw materials. The main output of three layers: three Xujiahe formation at the top of the lower Jurassic zhenzhuchong formation and middle lower Jurassic Ziliujing formation at the bottom. The chemical composition of the ore is 97.30 97.32% alumina: silica, 0.97 ~ 1.04%, 0.62 ~ 0.67% of iron oxide, calcium oxide 0.034 - 0.043%, 0.003% p2o5. The water absorption rate is 1.01 to 2.55%, and the refractoriness is between 1716 - 1723 DEG C.
Iron oxide, ferric oxide, alias burning limonite, burnt ochre, rouge, iron red, red, Venice red (mainly iron oxide). Chemical formula Fe2O3, soluble in hydrochloric acid, red brown powder.
