Abstract
Method for manufacturing porous products consisting essentially of titanium suboxide(s) of general formula TiOx, the value of x being between 1.6 and 1.9, the method including a) mixing the raw materials including at least one source of titanium dioxide, a reducing agent comprising carbon, b) forming the product, c) optionally, in particular when organic products are used during step a), thermal treatment under air or an oxidizing atmosphere, d) sintering, for example at a temperature above 1150° C. but not exceeding 1430° C., under a neutral or reducing atmosphere, in which the source of titanium dioxide consists of at least 55 wt % of anatase.
