Titanium oxide precursor and production method thereof, and production method of titanium oxide using the precursor |
摘要 |
<p>A titanium oxide precursor which is used for producing a fine-particle titanium oxide showing a high photocatalytic activity is provided. The titanium oxide precursor is an oxygen-atom-containing titanium compound other than anatase-form titanium oxide, and has a maximum exothermic peak at a temperature in the range of from about 30 DEG C to about 500 DEG C in a differential thermal analysis curve and shows decrease in weight in a thermogravimetry curve at about the same temperature at which the maximum exothermic peak is shown in the differential thermal analysis curve when subjected to a thermogravimetry and differential thermal analysis under the condition of a temperature rising rate of 20 DEG C/min.</p> |
