Inorganic silicon compounds were a series of inorganic chemicals that developed rapidly in the 1980s, especially in recent years. Among the inorganic chemicals in the patent index of the de winter center, the amount of patent abstracts of silicon compounds accounts for an absolute advantage. It can be seen that inorganic silicon compounds are obviously competitive among many inorganic chemicals. Throughout the world, the new varieties of silicon compounds have not increased much in recent years, while the development of inorganic silicon compounds is more important. For example, sodium silicate, the oldest silicon compound, is also developing towards high performance and high added value; American Mobil company has developed various specifications of ZSM zeolite, which can be used in almost all catalytic processes of petrochemical industry; Silicon nitride ceramic engine is marching towards practicality. Therefore, from the current development trend, inorganic silicon compounds will enter a large number of light industry, food, medicine, construction, electronics, metallurgy, machinery industry and many other fields, which must have great development prospects.


The appearance of white carbon black is white highly dispersed amorphous powder or flocculent powder, and some are processed into granules as commodities. The specific gravity is 2.319 ~ 2.653, and the melting point is 1750 ℃. Insoluble in water and most acids, it will become aggregated fine particles after absorbing water in the air. Soluble in caustic soda and hydrofluoric acid. It is stable to other chemicals, resistant to high temperature, does not decompose, and does not burn. It has high electrical insulation and porosity. The internal surface area is large, which has a large dispersion force in raw rubber. Hydrophobic white carbon black treated by surface modification is easily soluble in oil. As a reinforcing filler for rubber and plastics, it will significantly improve the mechanical strength and tear resistance of its products. Due to different manufacturing methods, the physicochemical properties and microstructure of silica will be different, so its application fields and effects are also different.


China's white carbon black products are mainly developed after liberation, and there are only dozens of varieties so far, so the gap is still large. China has high-quality and rich resources, which provides a material basis for the research and development of more silicon compounds.


It can be expected that the development speed of silica in China will be faster and faster, and the gap with the developed countries in the world will be smaller and smaller.
