Advantages and disadvantages of wet-processed Barium Fluoride BaF2 products
Using hydrogen fluoride as a fluorine source: using barium carbonate or barium hydroxide to react directly or indirectly with hydrofluoric acid. Let's talk about the advantages and disadvantages of this method to make Barium Fluoride BaF2 products.
Advantages and disadvantages: The production process is relatively mature, the utilization rate of raw materials is high, and the reaction produces by-products gas and water. Barium Fluoride BaF2 products are not affected by other ions during crystallization, and it is easy to obtain high-purity products from high-purity raw materials. However, the equipment is seriously corroded, and a large amount of hydrofluoric acid is directly or indirectly required for production. Hydrofluoric acid is mainly produced by the reaction of fluorite and sulfuric acid. If efforts to limit the mining of fluorite are increased, the price of the corresponding hydrofluoric acid will inevitably rise. , which in turn affects the production cost of the process. In addition, the production process is accompanied by a large amount of mother liquor discharge, which causes great pressure on environmental protection.
Using soluble salt as fluorine source: Using the low solubility of Barium Fluoride BaF2 products in aqueous solution, soluble barium salt solution and soluble fluoride salt solution are reacted to form Barium Fluoride BaF2 products precipitation.
