Brief Introduction
The super fine silica/quartz/crystal micro powder is out of super purified and high quality natural silica ore by applying special hi-tech methodology in the process of preliminary selecting, fragmenting, grinding, purifying, dehydrating, classifying and so on. This technology enabled the Sino Surplus International Limited(SinoSi) the first mover as well as the leading producer and research institute in this industry. This product enjoys unmatched fineness, granularity, stability and know-how. The specific feature of free coarse granules and perfect chemical stability makes the super fine silica powder become the best filling materials and additive in comprehensive applications including paint-coatings, adhesive, sealants, silica gels and epoxy resins and etc.　

Because of its special properties and excellent characteristics the silica powder is widely used in areas of electronics, electrical apparatus, chemical industry, special micro motor, sealing of transistor and semi-conductor components, insulation casting of current transformer, voltage transformer, electronic transformer and dry -type transformer, epikote casting of high-tension cable connection, high-voltage insulator, high-voltage switch, insulation pipes and components of high-voltage electrical apparatus. The silica powder is also used in electric welding industry as protection coating. In addition, it acts well as epoxy powder coating and as the filling materials for arc resistant and weathering resistant surface painting. As the filling material for epikote, silicon micro powder applies to both large-scale components and small-scale precise electrical components.

According to our recent research and wide application, the abovementioned properties as well as its perfect effect become quite obvious and extremely successful in the pouring-sealing of integrated circuit chip transistors, magnetic head, and etc. It is proved to be the most applicable filling material.
