Anhydrous Lithium Metaborate (LiBO2, CAS 13453-69-5), technical and reagent grade, supplied wholesale by Zyntex. Fusion flux for XRF glass beads and ICP/AAS sample preparation of rocks, ores, cements and ceramics. CoA and SDS.
Anhydrous lithium metaborate (LiBO2) is a white powder or granulate that melts at about 845°C. Molten, it dissolves oxide materials very efficiently, especially acidic, silica-rich samples.
Analytical laboratories mix it with samples and fuse them in platinum crucibles to produce homogeneous glass beads for X-ray fluorescence (XRF) or solutions for ICP and AAS analysis. Geological, mining, cement and ceramic laboratories use this borate fusion method because it eliminates mineralogical and particle size effects. Blends with Lithium Tetraborate are adjusted to the acidity of the sample.
Analytical grades must have very low levels of the elements to be measured. It is also used in glass and ceramic glazes. For the hydrated form, see Lithium metaborate 2-hydrate, and for related boron chemicals, Boric Acid.

⚠️ Safety & Handling: May cause eye and skin irritation; boron compounds may be classified as toxic for reproduction. Avoid dust formation and wear gloves, eye protection and dust protection. Store in tightly closed containers in a dry place, as the anhydrous product absorbs moisture. Always consult the Safety Data Sheet (SDS) for full classification and handling instructions.
When should lithium metaborate be blended with lithium tetraborate?
Metaborate-rich fluxes suit acidic, silica-rich samples, while tetraborate-rich fluxes suit basic samples. Blends are chosen to match the sample type.
Do you supply pre-fused fluxes?
Pre-fused, high-purity fusion fluxes can be quoted on request. Please specify the composition and impurity requirements.
