XRF Lithium Tetraborate 100%

This flux is classified as "acidic" and is generally used for higher concentrations of basic oxide samples or for samples containing high proportions of limestone. This flux is not suitable for highly acidic samples.
A major disadvantage of this flux is the relatively high melting temperature (925 degrees C) which causes accelerated wear on platinum apparatus and fusion equipment. In most parts of the world, this flux is being replaced by eutectic pre fused mixtures of lithium tetraborate/lithium metaborate, which give very satisfactory results with significantly lower melting temperatures, thereby prolonging platinum labware life and fusion apparatus.

Applications:
- Copper Sulphate
- Calcium Oxide
- Magnesium Oxide
