CAS 1330-43-4 Borax Anhydrous Na2B4O7 for Ceramic Frits, Purity 99.9% Sodium Tetraborate for Glazes and Enamels
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 help increase yields and reduce energy consumptions in glass, ceramic, and enamel frit production. Borax Anhydrous allows the formulation of low melting glazes and enamels with the correct thermal expansion. In enamels, it improves adhesion to metal by dissolving iron oxide and reducing melt surface tension.
The application of anhydrous borax in glazes 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.
Specific application examples: In the enamel industry, anhydrous
borax is commonly used in glazes and coated on metal surfaces,
which not only enhances the gloss and durability of enamel
products, but also improves the overall quality of the products.
