摘要:
Provided are novel titanium oxide particles, production method thereof, and applications which do not need a conductive aid or minimize the conductive aid. Novel titanium oxide particles 1 employ a three-dimensional network structure in which multiple crystallites 2 are coupled in sequence, and a magneli phase 2a is formed on the surface of the crystallites 2. The crystallites 2 are oriented at random, coupled with each other via pinacoid or end surface, and laminated as the three-dimensional network structure. A large number of spaces 3 in nano size is present in the titanium oxide particles 1, a grain boundary of the bonding interface is eliminated between the crystallites 2, while a large number of pores is present.

摘要:
A method and apparatus are described for manufacturing Ebonex® articles such as rods and tiles from titanium oxide precursors. The precursors are held within the interior space of a kiln and heated in a reducing gas. The precursors are held so that the reducing gas is able to fully envelop them. In a preferred embodiment, the precursors are hung from a support within the kiln. The temperature of the kiln is also controlled to limit the initial heating of the kiln and to maintain the kiln within a predetermined range of operating temperatures.
摘要:
The invention is directed to a catalyst having activity under the irradiation of a visible light, the catalyst being an oxide semiconductor such as an anatase type titanium dioxide, having stable oxygen defects. A method for producing a catalyst having activity under the irradiation of a visible light which comprises treating an oxide semiconductor with hydrogen plasma or with a plasma of a rare gas element, comprising performing the treatment in a state substantially free from the intrusion of air into the treatment system is also provided. An article comprising a base material having the catalyst above provided on the surface thereof and a method for decomposing a substance, comprising bringing an object to be decomposed into contact with the catalyst above under the irradiation of a light containing at least a visible radiation are disclosed. A novel photocatalyst which enables use of a visible radiation is provided, as well as a method utilizing the photocatalyst for removing various substances containing an organic matter or bacteria by photodecomposition.

A method of making an article which includes a suboxide of titanium, the method involving binding Magneli phase powder into the shape of an article and subjecting the bonded shape to heat treatment including the step of controlling the temperature and pressure of the heat treatment so that the heat treated article is substantially corrosion resistant and non-wicking in use.
摘要:
An electrical conductor formed substantially of a titanium sub-oxide having a formula TiO.sub.x where x is less than two. The conductor may take the form of a resistance heater which is compatible with ceramic insulators, and is useful because of its ability to withstand corrosive media and its very low coefficient of thermal expansion.
