How does lithium metaborate fusion work?
How borate fusion works. The borate fusion technique consists of mixing a ground sample with a borate flux (lithium or sodium) inside a 95% Pt – 5% Au crucible, heating to 1000 °C with agitation until the flux melts, and then dissolving the sample homogeneously in the flux.
What is lithium tetraborate fusion?
Sponsored by XRF ScientificSep 5 2017. Lithium borate fusion is a sample preparation method that allows samples to be presented to an x-ray spectrometer (XRF) for accurate analysis. Industries such as glass, steel, cement, nickel, copper and iron ore often use this method for sample preparation.
What is borate fusion?
Borate fusion is a widespread sample preparation method for XRF, AA and ICP analysis. For solutions, borate fusion is a rapid and safe method to eliminate the use of concentrated and dangerous acids (such as HF) in sample preparation. The preparation time is shorter than conventional acid digestions.
What is the formula for lithium borate?
Li2B4O7

How does borax flux work?
A mixture of borax and ammonium chloride is used as a flux when welding iron and steel. It lowers the melting point of the unwanted iron oxide (scale), allowing it to run off. Borax is also mixed with water as a flux when soldering jewelry metals such as gold or silver.
What is lithium borate used for?
Lithium borate can be used in the laboratory as LB buffer for gel electrophoresis of DNA and RNA. It is also used in the borax fusion method to vitrify mineral powder specimens for analysis by WDXRF spectroscopy.

How is a lithium tetraborate fusion flux prepared?
To perform sample preparation, the sample under test is weighed to an exact ratio with the lithium tetraborate fusion flux, and these weights are recorded. They are both placed in a platinum crucible and mixed before a fusion machine is used to heat the mixture until it melts together to form a single homogenous hot liquid.
How is Lithium metaborate used in rock formation?
Lithium metaborate is an effective flux for silicates and other rock-forming minerals. The glass resulting from fusion is mechanically strong, reasonably nonhygroscopic, and is readily soluble in dilute acids.
Which is the correct formula for lithium tetraborate?
Two basic formulations, lithium tetraborate (LiT or Li₂B₄O₇) and lithium metaborate (LiM or LiBO₂) are commonly used in various proportions. To ease the flux selection, we base the choice of the flux on the Acidity Index (Ai) of the sample. For a given oxide, this Index is the ratio between the number of atoms of oxygen and the atoms of metal.
Which is sample preparation method does borate fusion use?
Borate fusion is a widespread sample preparation method for XRF, AA and ICP analysis. It outperforms many other procedures for the preparation of a wide range of materials including: carbonates, catalyst, cement, ceramic, ferroalloys, geological samples, glass, pure metals, silica and slag.
