Calcium aluminate powder

Calcium aluminate powder is a grayish white powder. The main ingredient is a mixture of two calcium aluminate (CaO. 2A1203) and a calcium aluminate (CaO. A1203). It is slightly soluble in water and alkaline in water, with a pH value of about 11.
Calcium aluminate powder is highly reactive with inorganic strong acid and can be activated at room temperature. It has large heat discharge, fast heating up, and the dissolution rate of alumina can reach more than 90%. It can be used as raw material to produce liquid or solid polyaluminum chloride, which can simplify the process, reduce the cost and improve the quality of the product. It is the raw material used by most polyaluminum chloride manufacturers at home and abroad.
Application: calcium aluminate powder is mainly used for the production of aluminum chloride such as polyaluminum chloride, aluminum sulfate and sodium aluminate. It can also be used for the adjustment of basicity and also for refractory materials.
Quality standard: at present, there is no uniform quality standard in China, and its production inspection is carried out according to our company's O / GWDGS001 - 1999 standard.
