Aerogel powder particles are solid materials with a nano-porous network structure, featuring a porosity of over 90%, a thermal conductivity of less than 0.018 W/m·K, and pore sizes concentrated between 20-50 nanometers. They possess excellent properties, including low density, large specific surface area, high porosity, good light transmittance, low thermal conductivity, effective thermal insulation, strong adsorption capabilities, safety and environmental friendliness, non-toxicity, flame resistance, waterproofing, and non-corrosiveness.
