TITANIUM OXIDE PARTICLES, PHOTOELECTRIC CONVERTER USING SUCH TITANIUM OXIDE PARTICLES AND METHOD FOR PRODUCING SUCH TITANIUM OXIDE PARTICLES

摘要

Disclosed are titanium oxide particles which are generally equal in the primary particle size, do not agglomerate even when they are not dispersed in a dispersion liquid and is thus excellent in storage life, do not generate chlorine which is hard to handle, and has excellent dispersibility in an acidic aqueous solution. Titanium oxide particles (21c) contain 70-95 weight% of anatase crystals, and has a BET specific surface area of 65-120 m2/g and an oil absorption of 70-90 ml/100 g which is measured according to JIS K5101. Also disclosed is a photoelectric converter (10) comprising a light- transmitting base (11) and a porous film (21b) formed on the base (11) to which film a dye is adsorbed. This porous film (21b) contains the titanium oxide particles (21c).
