Description

Lithium Tetraborate Anhydrous is a high-purity inorganic salt essential for precise analytical and materials science applications. Its primary value lies in its role as a high-quality fluxing agent for X-ray fluorescence (XRF) and atomic absorption spectroscopy (AA) sample preparation, ensuring accurate and reliable elemental analysis. This product is critical for quality control laboratories in the mining, metallurgy, ceramics, and advanced glass manufacturing industries, where consistent fusion and minimal sample contamination are paramount.

Application

• Primary flux for X-Ray Fluorescence (XRF) and Atomic Absorption (AA) spectroscopy sample fusion.
• Production of specialty glass and ceramic glazes, where it acts as a flux to lower melting temperatures.
• Component in single crystal growth for electronic and optical applications.
• Raw material for synthesizing other lithium borate compounds and solid-state electrolytes.
• Use in laboratory research and development of new inorganic materials.
• Additive in welding and brazing fluxes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent caking and degradation. Keep container tightly sealed when not in use.
