Production method
Potassium carbonate neutralization method the dissolved potassium carbonate solution is placed in the reaction tank, boricacid is slowly added at a certain temperature for reaction, and the solution is filtered to remove the water insoluble matter.Then the potassium borate product was prepared by cooling, crystallization, centrifugation and drying. Reagent products canbe prepared by further refining.
Use
It is used in the manufacture of disinfectants, as a casein solvent and anti-wear additive, as a component of welding fluxesand
as a component of diazo developing solutions. In chemical analysis, the most suitable standard material used to determine the titration of acids.
