Description

Lithium Tetraborate Tetrahydrate, 99% is a high-purity inorganic salt widely used as a specialized fluxing agent and analytical reagent. Its primary value lies in its ability to lower the melting point of complex oxide mixtures, making it indispensable for precise sample preparation in elemental analysis. This product is essential for industries and laboratories requiring accurate and reliable material characterization, particularly in the analysis of minerals, ceramics, and metals. It is a critical component for ensuring consistent results in X-ray fluorescence (XRF) and other spectroscopic techniques.

Application

• X-Ray Fluorescence (XRF) Sample Fusion: Serves as a primary flux for preparing homogeneous glass beads from solid samples for accurate elemental analysis.
• Spectroscopic Analysis: Used in atomic absorption spectroscopy (AAS) and inductively coupled plasma (ICP) techniques for sample digestion and matrix modification.
• Ceramic and Glass Manufacturing: Acts as a flux to lower firing temperatures and modify the thermal and chemical properties of specialty glasses and ceramic glazes.
• Metallurgical Flux: Employed in metal refining and welding applications to dissolve oxides and purify molten metals.
• Laboratory Reagent: Utilized as a high-purity chemical for research and development in inorganic synthesis and materials science.
• Quality Control & Assurance: Critical for the calibration and standardization of analytical equipment in mining, geology, and industrial quality control labs.
