1、 Silicon dioxide

Silicon dioxide can be classified according to the manufacturing method and can be divided into precipitated silicon dioxide and gas-phase silicon dioxide. More than 90% of China's silica products are precipitated silica. Precipitation method silica, also known as precipitation hydrated silica, has a significant price advantage and accounts for over 90% of the domestic market share. It is widely used in rubber, tires, footwear, rubber and plastic products, as well as silicone rubber, coatings, cosmetics, toothpaste, feed and other industries.

2、 Precipitation method silica industry chain


The main raw materials required for precipitated silica are sodium silicate and sulfuric acid. The main raw materials of sodium silicate include soda ash, quartz sand, etc. The main raw material of sulfuric acid is sulfur. Precipitation based silica is widely used in industries such as rubber, tires, pharmaceuticals, pesticides, solid firefighting materials, agriculture, feed, coatings, inks, papermaking, etc. Among them, it relies heavily on the rubber industry.

3、 Analysis of the current market situation of the global fumed silica industry


1. Yield

Gaseous silica, also known as fumed silica, is estimated to produce approximately 324000 tons of fumed silica worldwide in 2021, an increase of 8% year-on-year. The annual compound growth rate of global production from 2016 to 2021 was 4.58%. It is expected that the global production of fumed silica will reach 338000 tons by 2022
