Description

Lithium Metaborate is an inorganic lithium salt of metaboric acid, widely recognized for its role as a high-performance fluxing agent in analytical chemistry and materials science. Its primary value lies in its ability to dissolve refractory oxides and silicates at high temperatures, facilitating accurate elemental analysis. This compound is essential for laboratories and industries requiring precise sample preparation for techniques like X-ray fluorescence (XRF) and atomic absorption spectroscopy (AAS). Key users include analytical service providers, glass and ceramic manufacturers, and research institutions focused on geochemical and metallurgical analysis.

Application

• Fusion Flux for Analytical Chemistry: Primary use as a high-purity flux for dissolving silicate rocks, minerals, ceramics, and other refractory materials prior to elemental analysis by ICP-OES, ICP-MS, AAS, or XRF.
• Glass and Ceramic Production: Acts as a flux and component in specialty glass formulations, including low-melting glasses and sealing glasses, to modify thermal and chemical properties.
• Single Crystal Growth: Used as a solvent or flux in the growth of specific oxide single crystals for electronic and optical applications.
• Laboratory Reagent: Serves as a high-purity chemical reagent for research and development in inorganic synthesis and materials science.
• Welding and Brazing Fluxes: A component in certain flux formulations used for joining metals, helping to remove oxides and improve flow.
• Electrolyte Additive: Investigated for use as an additive in advanced lithium-ion battery electrolytes to improve stability and performance at high voltages.

Quality Control

Our Lithium Metaborate is manufactured under strict quality management systems to ensure batch-to-batch consistency and high chemical purity suitable for analytical and industrial applications. Production adheres to in-house specifications designed for performance as a fusion flux. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as assay, loss on drying, and trace metal impurities. We support traceability and compliance needs for global customers.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a cool, dry place at room temperature (15-25°C/59-77°F). Minimize exposure to ambient atmosphere during handling to prevent moisture absorption, which can affect performance. Store away from incompatible materials such as strong acids.
