Selection regarding the evaporation of ammonium fluoride
Thread Content
There is very little information available at the moment, and it’s difficult to find relevant data. I’m seeking help from fellow users:
1. Boiling point and solubility of ammonium fluoride solution
2. What materials can withstand the evaporation of ammonium fluoride solution? 3. The temperature at which ammonium fluoride solution decomposes upon heating to produce ammonia and hydrogen fluoride
The ideal material choice is a graphite concentration device.
Hello, OP! What is an ammonium fluoride solution made of? Is it an acid, a base, or something soluble in water? You need to make that clear! If it’s acidic, hydrogen fluoride is produced upon heating; if it’s alkaline, ammonium and similar substances are formed~~~~~··
If there’s a chance, let’s explore and learn together*
Hydrogen fluoride gas is essentially hydrofluoric acid; can graphite resist corrosion by hydrogen fluoride gas? ?
Graphite can resist gaseous hydrogen fluoride or hydrofluoric acid.
Select the process based on your original liquid material conditions and product requirements. Methods such as cooling crystallization, evaporation crystallization, and evaporation-cooling crystallization can be employed.
Impermeable graphite can be used
