Precipitation silica is a white,porous,amorphous hydrated silica powder that is chemically inert and resistant to high temperatures,nonflammable,non-toxic,tasteless and odorless.Because of its high electrical insulation and large internal surface area,it is widely used in rubber,food,medicine,coating and other fields of national economy.The basic situation of the production capacity and enterprise distribution of the main manufacturers of precipitated silica in China were reviewed.The current situation of import and export,consumption status and technological progress of the precipitated silica industry were introduced,and the application prospects of precipitated silica was presented.A reference to precipitation silica manufacturers and researchers engaged in precipitation silica technology was provided.
