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.

Q: How to wash the sandstone wall: Secondly。 To keep the air dry, the sandstone relief will be hydrated where the humidity is too high. Produce water spots, whitening, weathering, erosion, rust yellow and other diseases, destroying sandstone relief.

The interstitial material comprises two components of the cement and the clastic complex. Common cements are siliceous and carbonate cements; the miscellaneous component is mainly a finer clay or silty sand that is deposited at the same time. The composition and structure of interstitial materials reflect the geological environment and physical and chemical conditions of sandstone formation. Sandstone can be divided into three categories: quartz sandstone, feldspar sandstone and lithic sandstone. Sand and sandstone are the main reservoirs of petroleum, natural gas and groundwater. Sand and sandstone can be used as abrasives, glass raw materials and building stone materials.
