Lithium borate glasses
Web9 aug. 2024 · The purity of B 2 O 3, CaO, Li 2 CO 3, and Sb 2 O 3 was 99%. The obtained glasses are labeled Sb0, Sb1, Sb3, Sb5, and Sb8, according to the amount of Sb 2 O 3. The codes and chemical composition of the prepared antimony (III) oxide glasses are tabulated in Table I. WebMoreover, long-term analyses of the lithium–borate fusion glasses preclude the precise measurement of Li and B isotope ratios and the detection of low concentrations of Li and B on the contaminated instrument. Thus, the lithium–borate fusion techniques are not popularly used for LA-ICP-MS analysis currently.
