Potassium metaborate is used:

  • In the petrochemical industry
  • In the process of oil-and-gas extraction as an additive for drilling fluids
  • In the analytical chemistry and so on

Potassium metaborate simultaneously assures high pH level as well as anticorrosive, buffer, thixotropic and water-regulating effect along with increased temperature resistance. By courtesy of mentioned above effects potassium metaborate is efficient borate crosslinker which is used in the work process based on the hydraulic fracturing treatment. Besides that, potassium metaborate can be used in oil production fields in the process of drilling and borehole cementation as a thixotropic additive for all kinds of cement.

The main advantage of this kind of additives over others reactive chemicals is the low freezing point of potassium metaborate solutions that is below -200° C. This particularity allows usage of potassium metaborate in the North upon conditions of low temperature.
