Sodium fluoride production way

the preparation method of sodium fluoride, and everybody know about the below.

sodium carbonate or sodium hydroxide under stirring and hydrofluoric acid in carbon brick and lead-lined steel reactor for reaction. After centrifugal separation, drying and made. By fluorite, soda ash, quartz sand melt under 800 ~ 900 ℃, water leaching, the filtrate through evaporation, crystallization, drying system. Also can be made of byproduct gases from the phosphate fertilizer plant of sodium fluosilicate and sodium carbonate by 1:2 mole ratio of mixture, in about 80 ℃, the silica gel with sodium hydroxide dissolved into soluble silicate, then through crystallization filtration, separation, dry.

this is appropriate xin chemical co. , LTD. Shanghai explain for everybody about sodium fluoride production way, more consultation, can contact the appropriate Shanghai xin chemical co. , LTD. , welcome. To inquire.
