Title: Coagulated titanium dioxide and production thereof
Inventor: MURASAWA SADAO
IPC: G03G5/08
Filed: 1989-12-27
Abstract: PURPOSE:To obtain a coagulated titanium dioxide, suitable as an electrophotographic photoconductor and excellent in electrophotographic characteristics by heating an acidic aqueous solution containing dissolved titanium therein, hydrolyzing the aqueous solution in the presence of a rutile type seed crystal and then calcining the formed precipitates. CONSTITUTION:An acidic aqueous solution containing dissolved titanium therein is hydrolyzed in the presence of a rutile type seed crystal for hydrolysis to form precipitates, which are then calcined at 700-900 deg.C. Thereby, primary particles are calcined to provide the objective titanium dioxide. A preferred rutile type seed crystal for the hydrolysis used is fine titania sol having a rutile type crystal structure. The seed crystal is a sol of a fine hydrated titanium dioxide exhibiting peaks of the rutile type crystals by measurement using an X-ray diffractometry. The above-mentioned calcined substance is normally roughly crushed and then classified. The calcined coagulated titanium dioxide is further subjected to treatment with a mineral acid to provide better electronic characteristics, such as photosensitivity, dark decay ratio and moisture resistance than those of the titanium dioxide without being subjected to the treatment.
