Description

Forsterite (Mg2(SiO4)) is a naturally occurring magnesium silicate mineral and a key member of the olivine group. It is valued for its high melting point, excellent refractory properties, and chemical stability under basic conditions. This material is essential for industries requiring durable, high-temperature materials and specialized refractory linings. CAS No. 15118-03-3.

Application

• Refractory Manufacturing: A primary component in the production of forsterite bricks and monolithic refractories for steel, cement, and glass furnace linings.
• Ceramics & Enamels: Used as a raw material in high-temperature ceramics and as an opacifier in ceramic glazes and porcelain enamels.
• Foundry Sands: Employed as a specialty molding sand in metal casting for its thermal stability and low thermal expansion.
• Thermal Insulation: A key ingredient in insulating materials and boards designed for extreme temperature environments.
• Electronics Substrates: Utilized in the production of ceramic substrates for electronic components due to its favorable dielectric properties.
• Slag Conditioner: Acts as a conditioning agent in metallurgical processes to control slag viscosity and composition.
• Geopolymer & Cementitious Binders: Investigated as a precursor material in the development of novel, low-CO2 geopolymer cements.
• Laboratory & Research: Serves as a standard material in geological studies, high-pressure experiments, and materials science research.

Quality Control

Our Forsterite products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry specifications. Key parameters such as chemical composition, particle size distribution, and refractory properties are strictly monitored. Certificates of Analysis (COA) detailing purity, major oxide content (MgO, SiO2), and impurity levels are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from incompatible materials such as strong acids. The product is not hygroscopic under normal conditions but should be protected from prolonged exposure to moisture to prevent caking.
