Title: Method of producing hydrophobic silica fine powder
Inventor: NOZAWA YASUAKI
IPC: C01B33/18
Filed: 2000-03-24
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing hydrophobic silica fine powder by treating a silica fine powder produced by thermal decomposition method having silanol groups on the surfaces, with an organohalosilane. SOLUTION: This method of producing the hydrophobic silica fine powder by treating a thermal decomposition method silica fine powder obtained by the thermal decomposition of a silane compound with an organohalosilane in a fluidized bed, is characterized in that the gas flow rate in a fluidized tank is made to be 1.4 to 3 cm/sec. Thereby, the objective treatment degree can be achieved with the silane in a reduced amount based on silica by the method which facilitates the control of production conditions. Since the non-reacted silane in the waste gas is little, the clogging of piping due to the polymerization of the silane is largely reduced. The small gas flow rate means that the gas for the flow is a little, and the method thereby has merits comprising the reduction in the amount of nitrogen used therein and the lowering in the cost of the treated silica.
