The invention provides an anhydrous hydrogen fluoride production process; reaction raw materials fluorite powder and sulfate are mixed by an external mixer and enter into a converter with jacket; hot air with the temperature of 350 DEG C to 600 DEG C is fed in the jacket; the fluorite powder and the sulfate have chemical reaction and produce hydrogen fluoride; the produced hydrogen fluoride enters into a scrubber from a furnace header to be washed; the washed hydrogen fluoride enters into an intermediate tank from a condenser, and then receives distillation and degasification to prepare the finished product anhydrous hydrogen fluoride; solid residue is emitted from a furnace tail.

When the molar fraction of SnO2 is 83%, the main component of the coating isO2 solid solution with rutile structure. When the molar fraction of SnO2 is 44%, the main components of coating are theO2 solid solution with rutile structure andO2 solid solution with fluorite structure. When the molar fraction of SnO2 is 17%, the main component of the coating isO2 solid solution with fluorite structure. Annealed at higher temperature than 450 ℃, CeO2 is found in the coating containing 83%Sn, and there is not SnO2 in the coating containing 83%Ce, which suggests that fluoriteO2 has higher thermal stability than rutileO2. When the molar fraction of SnO2 increases, the dispensability of the coatings is improved greatly.
