Lithium Metaborate (CAS 13453-69-5)

Lithium metaborate (LiBO2), with a CAS number of 13453-69-5, is a chemical compound that serves as an important reagent in various non-medical research contexts, particularly in analytical chemistry. This white, crystalline solid is known for its strong fluxing properties, which are utilized to dissolve metal oxides at high temperatures—a process crucial in the preparation of samples for analysis. One of the main applications of lithium metaborate is in the fusion technique for X-ray fluorescence (XRF) spectroscopy and inductively coupled plasma (ICP) spectroscopy. During these processes, lithium metaborate lowers the melting points of the sample mixtures, thereby facilitating the complete dissolution of samples into a homogeneous glass, free from undissolved particles. This is essential for achieving accurate, consistent analytical results when determining the elemental compositions of various materials. Additionally, lithium metaborate is employed in the synthesis of special glasses and ceramics, where it influences the properties of these materials, such as lowering their viscosity and modifying their thermal expansion coefficients. In the field of geochemistry and environmental science, lithium metaborate is used in the analysis of soil and rock samples, helping to understand geochemical processes and the distribution of minerals within the Earth′s crust.
