Characteristic & Application

Sodium Cryolite also known as Sodium Aluminium Fluoride and Synthetic Cryolite occurs as white  odourless powder. It is insoluble  in  water  and dissolves in perchloric acid. Synthetic Cryolite is used in bonded abrasives and  grinding  wheels  as  a  filler.  It  is  also  used  for  other  metallurgical applications such as foundry additives for aluminium smelting, exothermic sleeves & cover flux
