Lithium metaborate is an effective flux for silicates and other rock-forming minerals. An improved lithium metaborate fusion technique for inductively coupled plasma mass spectrometric analysis of felsic rocks is proposed. The determination of fluorine in silicate materials with a fluoride ion-selective electrode following fusion with lithium metaborate is described.
