Silicon Micro Powder
Application and Structural Characteristics
Silicon micro powder is an industrial mineral filler primarily composed of high-purity silicon dioxide, produced through fine processing and strict particle size classification.
It features stable chemical properties, low impurity content, and controlled particle size distribution, and is widely used to enhance mechanical performance, wear resistance, heat resistance, and dimensional stability of material systems.
In practical applications, silicon micro powder is commonly used in resins, rubber, coatings, electronic packaging materials, and related industrial products. Different particle size grades can be selected according to specific process requirements to achieve filling, reinforcement, or functional performance adjustment.
