What is the function of ultrafine silicon powder

     Ultrafine silicon powder, as the name suggests, is fine. However, for different fields or engineers, the particle size range of ultrafine silicon powder varies, basically referring to silicon powder in the range of 1.5um-10um. The use is quite extensive. The inherent characteristics of silicon micro powder include acid and alkali resistance, hardness, wear resistance, thermal stability, insulation, and the addition of silica into very fine powder, resulting in an increase in specific surface area. When filled, it can also play a reinforcing role and improve the mechanical properties of the material. Various physical properties have made this type of silicon powder widely used, involving industries related to materials such as rubber, plastics, fibers, coatings, inks, ceramics, and casting. However, the difference in quality of ultrafine silicon powder can directly affect the performance of the material.

    Silicon micropowder is used as an electronic assembly material, mainly to prevent water, dust, harmful gases, vibration, external force damage, and stabilize circuits. The addition of high-purity ultra-fine and nano silica in epoxy plastic packaging electronic materials with a content of over 70-90% can give them excellent processability, low shrinkage, low coefficient of thermal expansion, good acid and alkali resistance, and solvent insulation.
