| [Molecular formula]: |
AlF3 |
| [Molecular weight]: |

| [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 1,291oC. At 300-400oC, 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! |
