Abstract

This method describes the addition of cerium (IV) oxide to a lithium borate flux. CeO2 provides a non-analytic glass former to the melt production. CeO2 also acts as an interelemental buffer replacing the use of lanthanum oxide for long wavelength absorption. With cerium oxide addition, excellent results are produced, resulting in part from the elimination of recrystallization problems encountered with lanthanum oxide use. Analytical results easily meet the ASTM C-114 qualification requirements for rapid method analysis of hydraulic cements.
