Lithium tetraborate fusion

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.
