Description

Lizardite CAS NO 12161-84-1 is a naturally occurring, layered magnesium silicate hydroxide mineral belonging to the serpentine group. This material is valued for its unique structural and thermal properties, making it a versatile industrial mineral. It is primarily utilized in sectors such as ceramics, refractories, and as a filler material where thermal stability and chemical inertness are required.

Application

• Refractory and Ceramic Production: Used as a raw material in the manufacture of heat-resistant bricks, kiln linings, and ceramic bodies due to its high-temperature stability.
• Filler and Extender: Acts as a functional filler in polymers, paints, and coatings to improve mechanical properties, thermal resistance, and reduce material costs.
• Construction Materials: Incorporated into cement, concrete, and asphalt mixtures to enhance durability and modify specific material characteristics.
• Catalyst Support: Serves as a substrate or support material for various industrial catalysts, leveraging its surface area and stability.
• Agriculture and Soil Amendment: Utilized to adjust soil pH and provide a slow-release source of magnesium and silica for plant nutrition.
• Specialty Composites: Employed in the development of composite materials requiring specific dielectric or insulating properties.
