Porous ceramic products of titanium sub-oxides
The invention relates to a method for manufacturing porous products made up essentially of titanium sub-oxide(s) with generic formulation TiOx, the value of x being from 1.6 to 1.9, said method comprising the following steps: a) mixing raw materials comprising at least one source of titanium dioxide, a reducing agent comprising carbon; b) shaping the product; c) optionally, in particular when organic products are used during step a), thermal treatment in air or oxidising atmosphere; d) sintering, for example at a temperature higher than 1150°C but not exceeding 1430°C, under a neutral or reducing atmosphere, in which the source of titanium dioxide is made up of at least 55 wt% of anatase. The invention also relates to a product that can be obtained by such a method.
