Provided are: titanium oxide fine particles having small primary particle diameters and small agglomerated particle diameters; and a method for producing titanium oxide fine particles. The BET diameters of the titanium oxide fine particles are 1-50 nm; the agglomerated particle diameters thereof are 1-200 nm; and the (agglomerated particle diameter)/(BET diameter) ratio is 1-40. Titanium (oxy)chloride is hydrolyzed in an aqueous solvent, while controlling the pH range and the temperature range. Preferably, titanium (oxy)chloride is subjected to a primary hydrolysis in an aqueous solvent, and a secondary hydrolysis is subsequently carried out, while adding titanium (oxy)chloride thereto.


Provided is a titanium dioxide pigment having minimal yellow color and minimal yellowing due to exposure, i.e., good yellowing resistance and high pigment performance such as brightness. Also provided is a titanium dioxide pigment which has a reduced amount of volatile moisture and which does not readily decompose when blended with a resin or the like. In the present invention, a compound including 0.05-20% by mass of phosphorus and an alkaline earth metal is present on surfaces of titanium dioxide particles having an average particle diameter of 0.15-1.0 m. The titanium dioxide pigment is manufactured by mixing an alkaline earth metal compound, a phosphate compound, and titanium dioxide particles having an average particle diameter of 0.15-1.0 m, and bonding the compound including phosphorus and an alkaline earth metal to the titanium dioxide particles.

Titanium dioxide and an electro-conductive titanium oxide which each includes particles having a large major-axis length in a large proportion and comprises columnar particles having a satisfactory particle size distribution. A titanium compound, an alkali metal compound, and an oxyphosphorus compound are heated/fired in the presence of titanium dioxide nucleus crystals having an aspect ratio of 2 or higher to grow the titanium dioxide nucleus crystals. Subsequently, a titanium compound, an alkali metal compound, and an oxyphosphorus compound are further added and heated/fired in the presence of the grown titanium dioxide nucleus crystals. Thus, titanium dioxide is produced which comprises columnar particles having a weight-average major-axis length of 7.0-15.0 m and in which particles having a major-axis length of 10 m or longer account for 15 wt. % or more of all the particles. A solution of a tin compound and a solution of compounds of antimony, phosphorus, etc. are added to a suspension obtained by suspending the titanium dioxide. The particles are sedimented. Subsequently, the product obtained is heated/fired to produce an electro-conductive titanium oxide which comprises the titanium dioxide and an electro-conductive coating formed on the surface thereof.

The purpose of the present invention is to provide a metallic copper dispersion: capable of maintaining dispersion stability of metallic copper particles for a long period of time; suitable for inkjet printing, spray coating, or the like; and capable of allowing a metallic copper-containing film having an excellent electrical conductivity and metallic color tone to be manufactured in a simple manner by performing low-temperature heating or plasma irradiation after application. The metallic copper dispersion is a dispersion containing at least an organic solvent, a polymer dispersant, and metallic copper particles having gelatin on the particle surface, wherein the metallic copper particles in the dispersion have a cumulative 50% particle size (D50) of 1-130 nm and a cumulative 90% particle size (D90) of 10-300 nm, and the polymer dispersant has an amine number of 10-150 mgKOH/g. The metallic copper dispersion is manufactured by reducing copper oxide in an aqueous solvent in the presence of gelatin, then performing solid-liquid separation, and then mixing the obtained metallic copper particles having gelatin on the particle surface and the polymer dispersant into the organic solvent.
