Calcium silicate powder is an inorganic silicate compound synthesized from calcium oxide and silicon dioxide at high temperatures, typically existing as a fine white powder in either amorphous or crystalline form. With its stable chemical properties, low thermal conductivity, and excellent adsorption characteristics, it plays a vital role across multiple sectors including industrial manufacturing, building materials, and environmental engineering.
We professionally supply calcium silicate powder in multiple specifications ranging from industrial grade to high-purity reagent grade. Particle size, purity, and activity can be customized to meet your specific application requirements. We invite you to contact us for detailed information and samples.
High whiteness and purity
Porous structure and high adsorption capacity
High-temperature resistance and thermal insulation
Environmentally friendly, safe, and non-toxic
Ceramics and Metallurgy: Used as a fluxing agent and structural stabilizer in ceramic bodies and glazes. In metallurgy, it serves as a foundry additive or furnace lining material.
Plastics, Rubber, and Coatings: Functions as a high-performance filler and reinforcing agent, effectively enhancing the mechanical strength and heat resistance of plastic and rubber products. It also regulates the leveling and abrasion resistance of coatings.
Environmental Protection and Agriculture: Leveraging its porous structure and chemical properties, it adsorbs heavy metal ions in wastewater treatment or functions as a soil conditioner in agriculture, regulating pH levels and loosening soil structure.
Food and Pharmaceuticals: High-purity grades serve as anti-caking agents in food products, disintegrants in pharmaceuticals, or carriers, ensuring safe application under strict manufacturing protocols.
Q1: Is this powder safe for humans and the environment?
A1: Chemically stable and generally considered safe and non-toxic. However, as a fine powder, prolonged inhalation should be avoided during handling. Wear dust masks and use in well-ventilated areas. Its environmental impact is minimal.
Q2: What distinguishes industrial-grade from pharmaceutical-grade products?
A2: The core differences lie in purity, impurity control, and production standards. Industrial-grade products prioritize physical and chemical performance metrics.
Q3: How should I select the appropriate particle size specification when purchasing?
A3: This depends on your downstream process and the performance requirements of the final product. For example, finer particle sizes enhance surface finish and strength when used as fillers, while specific particle size distributions may be required for adsorption or friction materials. Our technical team can provide selection recommendations.
