Aluminiumfluorid

aluminium fluoride,Molecular formula : AlF3 Molecular weight : 83.98 Property : White crystal or powder. Relative Density 2.882,25, hard to solve in water, acid and alkali solution, insoluble in most orgno solvents and insoluble in hydrofluoric acid and liquid hydrogen fluoride; it is quite stable. When heated, it does not decompose, but sublimate. Temperature of sublimation is 1,291°C. At 300-400°C, part of it will be hydrolyzed to hydrogen fluoride and aluminum chloride by vapor.Its hydrate include AlF3 .1/2H2O, AlF3. H2O, AlF3 .3H2O, AlF3 .3/2H2O and AlF3 .9H2O; toxic!Product quality : Company standardIndex nameIndexIndex nameIndexFirst gradeSecond gradeFirst gradeSecond gradeF,% ≥6160 SiO2+Fe2O3 %,≤0.300.30Al,% ≥3030 Sulfate(SO4) %,≤0.150.20Na,% ≤0.40.5P2O5 %,≤0.0050.005Water content(H2O),% ≤7.07.5Chemical ingredients are on dry base.
