Description

White Granular Borax Anhydrous for Borosilicate Glass, CAS 1330-43-4 Sodium Tetraborate Na2B4O7 for Glass 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 Boronsilicate Glass Making

In borosilicate glass manufacturing, borax anhydrous has advantages over 5- and 10-mol borax.

Borax anhydrous has a higher bulk density and melts more rapidly, even with minimum energy. Borax anhydrous is also a source of sodium and can be used with boric acid or boric oxide to control the sodium oxide/boric oxide ratio in the glass.

Borax anhydrous can be used to formulate glasses with low thermal expansion (high thermal shock resistance) and good chemical durability. Borax anhydrous acts as both a flux and network former.

Borax anhydrous allows the formulation of low-melting glazes and enamels with the correct thermal expansion in glass and enamel production.

Borax anhydrous is used as a source of B2O3 in the manufacture of many different types of borosilicate glass, including:

1. Heat and chemical resistant glasses

2. Illumination glasses

3. Optical lenses

4. Medical and cosmetic containers

5. Hollow microspheres

6. Glass beads

In the manufacturing process, borax anhydrous can increase furnace productivity. It has a higher bulk density and melts more rapidly with minimum energy than borax (5 and 10 mol). Borax anhydrous also provides a source of sodium and can be used with boric acid or boric oxide to control the sodium oxide/boric oxide ratio in glass.
