Turkey ETiBOR-68 Borax Anhydrous, White Granular HS Code 28401100 Na2B4O7 Sodium Tetraborate 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 Glass Making
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 role of anhydrous borax in glass
1. Enhanced thermal stability: Anhydrous borax can enhance the thermal stability of glass and
improve its heat resistance.
Improving Transparency: Anhydrous borax can increase the
transmittance of ultraviolet rays and enhance the transparency of
glass.
2. Enhance mechanical properties: Anhydrous borax can improve the impact resistance mechanical
properties of glass, making it more durable.
3. Flux function: In the glass manufacturing process, anhydrous borax serves as a
flux, which can lower the melting point of the glass and make it
easier to melt.
4. Control melting point and properties: Boron oxide in anhydrous borax acts as both a flux and a network
former in glass, controlling the melting point of the glass and the
properties of the final product.
