Web1 nov. 1970 · Abstract. 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. These characteristics lead to its use in X-ray spectrography and in methods which require whole-rock solutions, such as atomic ... WebThe borate fusion consists of mixing a powder sample with a fusion flux inside a platinum-5% gold crucible, heating to about 1000 – 1150 °C with agitation until complete reaction and dissolution to form a homogeneous molten glass. The molten glass is then cast into the beaker until the vitreous mass is thoroughly dissolved.

Weblithium tetraborate fusion using an apparatus consisting of a 12V (400A) power source coupled with graphite electrodes utilized as crucibles. It allows analyzing few mg of powdered rock and, therefore, it could be useful in the case of low sample availability. An automated analytical protocol that allows determination of 25 ele- Web5 mei 2024 · Lithium tetraborate (Li 2 B 4 O 7) remains the most commonly utilized flux chemical for both X-ray fluorescence (XRF) and inductively-coupled plasma mass spectroscopy (ICP-MS). Lithium tetraborate is transparent to light element X-rays, so it will not interfere with important spectral analyses. sheldon sitcom
