Spectroflux 100, Lithium tetraborate


Chemical Properties

Melting point
Soluble in water.


A general purpose acidic flux for fusing basic oxides, carbonates, alumino-silicates, glass, ceramics, cement steel, aluminum, concrete mixes, soils, magnesites, bauxites and rare earth oxides. Dissolves most refractories. Not suitable for highly acidic samples. Samples must be fully oxidized.Spectroflux 100, Lithium tetraborate is used in enamels. Further, it is a spectroscopic fluxing agent which is utilized for fusing basic oxides, glass, alumino-silicates, ceramics, carbonates, cement, steel, aluminum, soil, concrete mixes, bauxites, magnesites and rare earth oxides. In addition to this, it is used for dissolution of samples containing a high concentration of basic oxides and carbonate rocks and aluminosilicates.


Incompatible with strong oxidizing agents and strong acids, acid anhydrides and alkali metals.
