Document Type and Number:
Japanese Patent JP2013520394
Kind Code:
A
Abstract:
The present invention mainly relates to a process for manufacturing a doped or non-doped ZnO material and to the doped or non-doped ZnO material obtainable by said process. Said material shows very interesting thermoelectric properties. Said process comprises:
a) mixing powders of ZnO, of at least one oxide of doping element, if any, and of at least one solid pore forming agent, said at least one solid pore forming agent, suitable to generate an open porosity, being used in a ratio, with regard to ZnO and the at least one oxide of doping element, if any, of at least 5 wt. % and having a mean size of at least 10 µm, to obtain a mixture,
b) forming said mixture to obtain a formed green body,
c) heat treating said formed green body to obtain a porous sintered body, showing an open porosity, and
d) annealing said porous sintered body in an inert or reducing atmosphere.
