Abstract

There is provided a process for manufacturing aluminium fluoride having larger particle size wherein a by product of the fertilizer industry predominantly containing hydrofluorosilicic acid is used as the staring material along with aluminium hydroxide. Solid aluminium fluoride as obtained by the process of the present invention has particle size in the range of 80 microns to 90 microns and moisture content less than 1%.
