What is cryolite? What's his use? In this regard, Jin Shengwei fluorochemical, a cryolite manufacturer, will tell you about the brief description and application of molten cryolite. Please see the following specific description:

introduce

The dissolution of alumina in molten cryolite is divided into two steps: rapid dissolution of alumina and falling off and dissolution of alumina with crust on the electrolyte surface The reason why the dissolution of alumina in molten cryolite changes from fast to slow is that the addition of alumina leads to the decrease of electrolyte temperature, the formation of alumina / electrolyte agglomeration on the electrolyte surface, and the decrease of the contact surface area between alumina and cryolite The dissolution rate of alumina is related to stirring speed, preheating temperature of alumina, system temperature and type of alumina

purpose

It is mainly used as flux for aluminum electrolysis; It is also used as a wear-resistant additive for grinding products, which can effectively improve the wear-resistant, cutting and cutting force of the grinding wheel, and prolong the service life and storage time of the grinding wheel; Ferroalloy and boiling steel flux, nonferrous metal flux, casting deoxidizer, alkene polymerization catalyst, as well as anti reflective coating for glass, emulsifier for enamel, opacifier for glass, flux for welding materials, filler for ceramic industry, pesticide, pesticide and other industries and enterprises.

The main content of this issue is these. I hope you have a better understanding of cryolite.
