Borax Anhydrous 99.5% – Glass/Enamel Flux
Anhydrous Sodium Tetraborate (Na₂B₄O₇) for Gold Refining, Ceramic Glazes, and Thermal Efficiency
1 The Product Narrative
In the West African mining sector, Borax Anhydrous is the flux of choice for smelting gold concentrates into high-purity doré bars—it lowers melting points and absorbs metal oxides into a clean, manageable slag.
For large-scale glass and ceramic factories, its dehydrated state (no water of crystallization) reduces energy consumption in furnaces by 15% and extends refractory life significantly.
Zero Crystallization Water: Freight & Energy Savings
By eliminating the 47% water weight of the common decahydrate form, we significantly reduce your freight costs per ton of B₂O₃ delivered. This lowers the carbon footprint of your supply chain and slashes your furnace melting energy consumption. For smelters, it ensures a dry flux that does not add hydrogen to the melt, preventing bubble formation in final doré bars.
