High silica can be converted into kaolin? Add or remove some of the substances, specific operations! Thank you
High silica containing SiO2 pure natural particulate quartz powder. It is brittle, without plasticity, powder is not hydrophilic, acid resistance is strong, differential thermal analysis has typical quartz differential thermal curve, the refractoriness is 1750~1832 degrees.. More than 90% silicon dioxide, a small amount of ferric oxide, three small two aluminum oxide.
In the 50% general and kaolin silica, and alumina was the main component, Magnesium Oxide, iron, sodium, calcium, potassium and other small, therefore, the two components have significant differences, its essence is far different. Rely on laboratory reagents to add remove some substances is almost impossible to get into high silica kaolin
