Borax (also referred to as sodium borate, tincal (/ ˈtɪŋkəl /) and tincar (/ ˈtɪŋkər /)) is a salt (ionic compound), a hydrated or anhydrous borate of sodium, with the chemical formula Na 2 H 20 B 4 O 17. [1][a] It is a colorless crystalline solid that dissolves in water to make a basic solution.

Borax (Na2B4O5(OH)4 · 8 H2O[2]) is a borate mineral found in evaporite deposits of alkaline lacustrine environments and as a surface efflorescence in arid regions. It is the chief mineral mined from the deposits at Boron, California and nearby locations, and is the chief source of commercial borax. [5]

2023年8月8日 · Borax, also known as sodium borate or sodium tetraborate, is a naturally occurring mineral that has been used for various purposes throughout history. It is composed of boron, sodium, oxygen, and water molecules. The chemical formula for borax is Na2B4O7·10H2O.

The mineral Borax was the primary source for the useful chemical borax, since only the water needs to be removed from the mineral to create the chemical. However, in 1926, the mineral Kernite was discovered in large quantities and is now the primary source of the chemical borax.

Borax belongs to a group of boron minerals called borates resembling quartz crystals, fibrous cotton balls or earthy white powders. They originated in hot springs or vapors associated with the outpouring of volcanic rocks such as the colorful formations of Artists Drive.

2017年2月20日 · With the development of extensive deposits of borate-minerals interstratified in thick sequences of Tertiary clays and sands, their winning becomes a strictly mining-enterprise, of the same kind and of the same certainty as the digging of coal or iron-ore.

Six primary steps are required to refine raw ore into refined borates. The bulk of this process was developed at our Boron Operations: Dissolving: Crushed ore is mixed with hot liquor—a combination of borates and water. The borates dissolve in the water.
