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. When the sample needs to be prepared for X-ray fluorescence (XRF ...
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 ...
