Overview
Calcium silicate nanoparticles are a specialized form of calcium silicate with particle sizes in the nanometer range. These particles exhibit unique properties due to their high surface area-to-volume ratio, making them valuable in various industrial applications. They are synthesized through methods like sol-gel processes or hydrothermal synthesis, allowing precise control over particle size and morphology. The material is known for its eco-friendly profile and compatibility with other composites.
Physical and Chemical Properties
The nanoparticles display exceptional thermal stability, withstanding temperatures up to 1540°C without decomposition. Their low thermal conductivity (approximately 0.05 W/m·K) makes them ideal for insulation applications. Chemically, they are inert under normal conditions but react with strong acids. The porous structure provides a large surface area (typically 100-300 m²/g), enhancing their effectiveness as adsorbents or catalyst supports.
Main Applications
In construction, they are used as lightweight fillers in fireproof boards and high-temperature insulation materials. Their nano-scale porosity improves mechanical strength while reducing weight. Environmental applications include wastewater treatment, where they adsorb heavy metals. In catalysis, they serve as supports for noble metal nanoparticles due to their thermal stability and surface properties.
Safety and Storage
As a fine powder, inhalation risks require dust masks and proper ventilation during handling. Skin contact should be minimized with gloves and protective clothing. Storage requires moisture-proof packaging in sealed containers. Bulk storage silos should include desiccants to prevent clumping. The material is non-flammable but may generate dust explosions in concentrated airborne forms.
B2B Procurement Guide
Industrial buyers should specify particle size distribution (commonly 20-100 nm), purity levels (≥98%), and surface area requirements. Technical datasheets should include XRD patterns and SEM images for quality verification. Leading manufacturers are concentrated in China, Japan, and Germany. Sample testing is recommended before large orders. Transportation costs are significant due to low bulk density; consider local suppliers for cost efficiency.
