Description

Lithium Metasilicate is an inorganic lithium salt of metasilicic acid, valued for its role as a high-performance flux and reactive intermediate in advanced materials. Its primary commercial significance lies in its ability to lower melting points and modify the thermal and chemical properties of glass, ceramics, and specialty coatings. This compound is essential for manufacturers in the glass, ceramic, and construction industries, as well as for researchers developing lithium-ion battery components and inorganic binders.

Application

• Glass & Ceramic Flux: A key component in frits, glazes, and enamels to reduce melting temperature and improve thermal shock resistance and chemical durability.
• Inorganic Binders & Coatings: Used in high-temperature resistant paints, anti-corrosion coatings, and refractory cements where silicate chemistry provides stability.
• Welding & Brazing Fluxes: Acts as a fluxing agent in electrode coatings and brazing pastes for joining metals, facilitating oxide removal and improving weld quality.
• Specialty Construction Materials: Incorporated into alkali-activated cements and geopolymers to enhance early strength and long-term durability.
• Electronics & Battery Research: Investigated as a precursor or additive in solid-state electrolytes and protective layers for lithium-metal anodes in next-generation batteries.
• Catalyst Support & Precursor: Serves as a support material or precursor for catalysts used in petrochemical and fine chemical synthesis.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry place at room temperature (15-25°C/59-77°F). To prevent caking and degradation, keep the container tightly sealed in a low-humidity environment. Store away from incompatible materials such as strong acids.
