Disodium Tetraborate Anhydrous for Glazes and Enamels, White Granular CAS 1330-43-4 Borax Anhydrous for Glazes
1. Borax Anhydrous Introduction
Turkey ETiBOR-68 disodium tetraborate anhydrous 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. Na2B4O7 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, isodium tetraborate anhydrous can be hygroscopically changed into borax decahydrate or borax pentahydrate.
We sell Chinese borax anhydrous, Turkey ETiBOR-68 disodium tetraborate anhydrous and US Na2B4O7.

3. Borax Anhydrous for Glazes and Enamels
Borax anhydrous can be used as a stabilizer and bonding agent in firebricks and castables. Borax anhydrous gives an intermediate-temperature glassy bond prior to ceramic bond establishment, at which point the borate compound is frequently volatilized from the system.
The application of anhydrous borax in glazes and enamels is mainly reflected in the following aspects:
1. Enhance luster and durability: Anhydrous borax is mainly used in glazes to enhance the luster and durability of ceramic products. It can improve the compressive strength, wear resistance, and chemical resistance of ceramics, making the product smoother and more perfect.
2. Reduce melting temperature: Anhydrous borax can lower the melting temperature of glazes, thereby reducing energy consumption and improving production efficiency. In addition, it can prevent glaze leakage during the firing process, further improving the quality of the product.
3. Improving the adaptability of glaze: Anhydrous borax improves the adaptability of glaze by controlling the coefficient of thermal expansion, reducing problems such as rough body and bright glaze surface, harmonizing glaze color, and preventing black spots and cracking of glaze surface.
4. Other Application for Borax Anhydrous
Borax anhydrous provides benefits across industrial applications
1.Acts as a solvent for metallic oxides at high temperatures
2. Serves as a cover flux to protect metal surfaces from air oxidation
3. Acts as a scavenger to dissolve metallic oxides and other contaminants in the production of ferrous and non-ferrous metals
4. Stabilizes stainless-steel slag, reducing slag dust and improving handling while minimizing explosion risk due to the absence of water molecules
5. Stabilizes and acts as a bonding agent in firebricks and castables
6. Provides an intermediate-temperature glassy bond prior to the establishment of the ceramic bond (at which point the borate compound is frequently volatilized from the system)
7.Reacts with polymers in oil production to create high-viscosity oil-well fluids that help increase the recovery of oil from subterranean formations
