Potassium triborate was synthesized with potassium carbonate and boric acid by controlling suitable feed mixture ratio,reaction temperature and dehydration temperature in the self-designed boiling reactor.

Study on potassium borofluoride production process by waste acid from hydrofluoric acid production;

This method adopted sulfuric acid to decompose potassium borofluoride to form potassium sulfate, then sodium tetraphenylborate was added to precipitate potassium ions, and finally the potassium borofluoride content was determined on the basis of the weight of formed potassium tetraphenylborate.

The preparation method of potassium pentaborate (KB5O8) was studied with the replacement reaction between potassium chloride and sodium pentaborate solution.

Five methods of producing potassium pentaborate were studied.
