Turkey ETiBOR-68 Borax Anhydrous Used in Metallurgy, White Granular Na2B4O7 Sodium Tetraborate for Fire Assay Flux
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 Fire Assay Flux and Metallurgy
Borax anhydrous is an excellent solvent for metallic oxides at high temperatures. Borax anhydrous is used as a cover flux to protect metal surfaces from air oxidation. It also serves as a scavenger to dissolve metallic oxides and other contaminants in the production of ferrous and nonferrous metals. Since boron is regarded as a unique and highly versatile alloying element in steel, borax anhydrous can be used to improve the properties and processing behavior of steel products.
The specific application effects of borax in fire assay flux include:
Improve melting and flowability: Anhydrous borax makes the sample easier to melt and flow, thereby
increasing melting efficiency.
Accelerated decomposition and oxidation reactions: Anhydrous borax can promote the decomposition and oxidation of
metals and sulfides, making them easier to separate and
precipitate.
Reduce impurity content: Through chemical reactions, anhydrous borax can remove impurities
from the sample and improve the assay efficiency.
In summary, borax anhydrous plays a crucial role in the flux of
fire assay, significantly enhancing the assay effect by improving
melting and flowability, accelerating decomposition and oxidation
reactions.
