Borax vs. Boron - What's the difference? Ask Difference

26-08-2018  The main difference between Borax and Boron is that the Borax is a boron compound, a mineral, and a salt of boric acid and Boron is a chemical element with the atomic number of 5. Borax, also known as sodium borate, sodium tetraborate, or disodium tetraborate, is an important boron compound, a mineral, and a salt of boric acid.

Boron - Wikipedia

Nearly all boron ore extracted from the Earth is destined for refinement into boric acid and sodium tetraborate pentahydrate. In the United States, 70% of the boron is used for the production of glass and ceramics. The major global industrial-scale use of boron compounds (about 46% of end-use) is in production of glass fiber for boron-containing insulating and structural fiberglasses, especially in Asia. Boron is added to the glass as borax pentahydrate or boron oxide, to influence the strength or fluxing q
