Turkey ETiMADEN Borax Decahydrate Granular Used in Metallurgy, CAS 1303-96-4 Sodium Tetraborate Decahydrate Na2B4O7.10H2O for Gold Mining
1. Borax Decahydrate Introduction
Borax decahydrate, also known as sodium borate decahydrate or simply borax, is a naturally occurring mineral compound that is often used in various household and industrial applications. It is composed of sodium, boron, oxygen, and water molecules.Borax decahydrate is a chemical substance with the molecular formula Na2B4O7 · 10H2O. It is a semi transparent colorless crystal or crystalline white powder. Borax decahydrate has no odor and a salty taste. When heated to 350-400 ℃, borax decahydrate will lose all its crystalline water and become anhydrous borax. Borax decahydrate is soluble in water and also in glycerol, but insoluble in alcohol. Its aqueous solution is weakly alkaline and appears colorless glassy when melted. We sell both Chinese brand purity 95%, 99.5% borax decahydrate and Turkey ETi Maden borax decahydrate.

3. Borax Decahydrate for Gold Mining
The role of borax decahydrate in gold extraction mainly includes removing impurities from gold and maintaining its purity. In the process of gold jewelry processing, borax decahydrate is used as a flux, which forms a crystalline substance after melting and burning, which can remove impurities from the surface of gold, accelerate the dissolution of gold, and maintain the purity of gold.
Borax decahydrate used in Metallurgy
1. Flux: In the metallurgical industry, borax decahydrate is used for calcination, welding, and metal testing, and is a good flux. Borax decahydrate can increase the melting rate of metals, improve the fluidity of the melt, and thus help improve smelting efficiency and product quality.
2. Deoxidizer and cosolvent: In the process of non-ferrous smelting, sodium tetraborate decahydrate can be used as a deoxidizer and cosolvent to help remove impurities and oxides from metals, and improve the purity and quality of metals. In addition, borax decahydrate can also serve as a purifying agent to further purify the metal surface and ensure the smooth progress of the smelting process.
3. Improve hardness and heat resistance: In the mechanical industry, sodium tetraborate decahydrate is used for surface boronizing treatment, which can improve the hardness and heat resistance of metals. This treatment can enhance the wear resistance and corrosion resistance of metals, and extend the service life of equipment.
5. Special steel production: Borax decahydrate is also used to produce high-strength boron steel, high hardness heat-resistant alloy steel, and special steel resistant to three acid corrosion. These special steels have excellent mechanical properties and corrosion resistance, and are widely used in fields such as aerospace and automotive manufacturing.
