Title: Production of particulate metallic compound
Inventor: SHIYUU TOKUGEN
IPC: C01B13/32
Filed: 1988-10-28
Abstract: PURPOSE:To obtain the title metallic compound free from particle flocculation with narrow particle size distribution, by mixing an organometallic compound hydrolyzable at low temperatures with a mixture of water and an organic solvent followed by raising temperature to effect hydrolysis to facilitate particle size control. CONSTITUTION:Firstly, distilled water or ion exchange water (esp. with an electrical conductance of <=2mus/cm) and an organic solvent (esp. with a freezing point of <=-10 deg.C, e.g., butanol, ethyl acetate, hexane, xylene) are mixed with each other in the amount of pref. 1-15 pts.wt. of the water based on 100 pts.wt. of the organic solvent. Thence, the resultant mixture is mixed with a hydrolyzable organometallic compound or its complex (e.g., an alkoxide of Si, Ge, Ti, Zr or Al) at such temperatures that said organometallic compound cannot be hydrolyzed (e.g., at <=-30 deg.C) followed by raising temperature to pref. <=0 deg.C (esp. <=-10 deg.C) to carry out hydrolysis for several minutes to 20hrs., thus obtaining the objective particulate metallic compound. Preferably, the amount of the organometallic compound to be used is 20-400 pts. based on 100 pts.wt. of a mixture of the water and the organic solvent.
