Boric acid:

Boric acid is obtained by reacting borax with mineral acid.

It is used in production of glass, fiberglass, ceramics, foundry, nickel plating, wood protection, buffer solutions, nuclear reactors.


Forms several crystalline hydrates with different water content. These crystalline hydrates and anhydrous sodium tetraborate Na2B4O7 are commonly referred to as "borax".

Examples of crystalline hydrates:

  • pentahydrate (Na2B4O7 .5H2O), the so-called "jewelry borax";
  • decahydrate (Na2B4O7 .10H2O).

It is a raw material for the production of boric acid and various boron compounds.

DISodium Octaborate Tetrahydrate:

Applies to:

  • Agriculture (fertilizers with trace elements, insecticides);
  • Wood protection products (insecticides, fungicides):
  • Flame retardants


A mineral belonging to the class of borates.

It is a valuable natural industrial raw material for the production of boron and boric acid.
