CAS 1330-43-4 Borax Anhydrous for Glazes, ETiMADEN Disodium Tetraborate Anhydrous Borax for Glaze Making
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 Glaze Making
1. Enhance the fluidity and smoothness of glaze: Borax anhydrous can improve the fluidity of glaze, making it easier to flow and spread during firing, resulting in a smoother glaze surface.
2. Improving the glossiness and brightness of glaze: Borax anhydrous can enhance the glossiness of glaze, making the surface of ceramic products smoother and brighter.
3. Enhance the adhesion and durability of glaze: Disodium tetraborate anhydrous can improve the adhesion and durability of glaze, reduce the risk of glaze layer peeling, and extend the service life of ceramic products.
4. Promoting chemical reactions: During the ceramic firing process, disodium tetraborate anhydrous can promote chemical reactions between the glaze and the ceramic body, making the glaze layer more uniform and smooth.
5. Improving the dispersibility and stability of pigments: Although anhydrous borax itself is not directly used as a pigment, it can play an auxiliary role in the preparation and application of ceramic pigments, improving the dispersibility and stability of pigments and enhancing the decorative effect of ceramic products.
