Synthetic cryolite powder is one kind of odorless white solid or powder.
Most cryolite is manufactured from aluminium oxides, hydrofluoric acid, and
sodium hydroxide or the equivalent reagent hexafluorosilicic acid:
6 NaOH + Al2O3 + 12 HF → 2 Na3AlF6 + 9 H2OIt was mined as cryolite at Ivigtût
on the west coast of Greenland, until the deposit was depleted in 1987.
