White Granular CAS 1330-43-4 Disodium Tetraborate Anhydrous, ETiBOR-68 Borax Anhydrous Na2B4O7 Borax for Gold Mining.Anhydrous borax appearance is white granular or colorless vitreous crystal. The melting point of alpha orthorhombic crystal is 742.5 ℃, and the density is 2.28; The melting point of beta orthorhombic crystal is 742.5℃, and the density is 2.28. It has strong hygroscopicity and can soluble in water and glycerol. It is slowly dissolved in methanol to form a solution with a concentration of 13-16%. the aqueous solution is weak alkaline, insoluble in alcohol. Anhydrous borax is the product obtained when borax is heated to 350-450 ℃. When placed in air, it can be hygroscopically changed into borax decahydrate or borax pentahydrate.

PRODUCT SPECIFICATIONS

Application

1. Used in glass industry

Anhydrous borax can be used in the manufacture of heat-resistant and high-quality glass and optical glass industrial.

2.Ceramic glaze industry

Borax anhydrous crystal can make the glaze not easy to fall off, and make the ceramics have glossiness

3.Welding industry

Disodium tetraborate anhydrous can also be used as a flux for alloys.

4.Agriculture industry

Disodium tetraborate anhydrous can be widely used as raw material of boron fertilizer

5.Boron Steel industry

Boron in steel is mainly to improve the hardenability of steel, and to improve the high temperature strength and creep strength of heat-resistant steel.

6.Chemicals industry

In chemical industry, borax anhydrous is an indispensable ingredient in the production of detergents, adhesives, and other chemicals reagents etc.

7.Borax Anhydrous Application in Gold Mining

In gold mining industry, borax anhydrous needs to be added. Borax anhydrous can purify gold and lower its melting point. Borax anhydrous is a fluxing agent with a fluxing effect.

When borax anhydrous is heated together with gold, it removes oxides attached to the metal surface, reacts with impurities, and floats on the metal surface without mixing with the metal. After the reaction between borax and gold is complete, put it into boiling oil. Borax decomposes into gas when exposed to heat, while gold remains unchanged when exposed to heat, thus removing borax adhering to the surface of gold.
