bauxite is not pure alumina, it will contain lots of other stuff. whatever doesn't evaporate at above 2,000 will be there, and that's lots of impurities

Hi there. Love your work. I have a question regarding aluminum oxide. What chemicals or oxides except cryolite, can reduce aluminum oxide melting point if you heat them together in a crucible in a furnace? I know this auestion is not in par with the video above but I dont have your email address. I will appreciate your feedback
