Amorphous fine-particle powder, method for producing the same and perovskite-type barium titanate powder produced by using the same |
| abstract |
The present invention provides an amorphous fine-particle powder which enables to obtain a fine perovskite-type barium titanate powder free from residual by-products such as barium carbonate and stable in quality, and a method for producing the amorphous fine-particle powder. The amorphous fine-particle powder is a fine-particle powder including titanium, barium, lactic acid and oxalic acid, wherein: the average particle size thereof is 3 μm or less; the BET specific surface area thereof is 6 m 2 /g or more; the molar ratio (Ba/Ti) of Ba atoms to Ti atoms is 0.98 to 1.02; and the amorphous fine-particle powder is noncrystalline in X-ray diffraction and has a peak of an infrared absorption spectrum in each of a region from 1120 to 1140 cm −1 and a region from 1040 to 1060 cm −1 . The method for producing an amorphous fine-particle powder brings a solution (solution A) that contains a titanium component, a barium component and a lactic acid component and a solution (solution B) that contains an oxalic acid component into contact with each other in a solvent that contains an alcohol. |
