When the dolomite sand (snowflake white) is heated to 700-900 ℃, dolomite is decomposed into a mixture of carbon dioxide, calcium oxide and magnesium oxide. It is called caustic magnesite and easily reacts with water. Put it at 1500 ° When calcined at C, magnesium oxide becomes calcium magnesium, and calcium oxide is transformed into crystalline a-cao, with compact structure, strong water resistance and high fire resistance of 2300 ° C。

Dolomite deposits in China are distributed in carbonate series. The older the strata, the more sediments, and most of them are concentrated in the lower Sinian period. For example, dolomite deposits exist in Liaohe Group in the northeast, Sangzi group in Inner Mongolia and Jianou group in Fujian Province. Secondly, the Sinian and Cambrian dolomite deposits are relatively extensive, such as Liaodong Peninsula, Eastern Hebei, Inner Mongolia, Shanxi, Jiangsu and other places. Dolomite deposits in Carboniferous and Permian are mostly distributed in Hubei, Hunan, Guangxi, Guizhou and other places.
