ABSTRACT:
A process for the preparation of shaped, electrically conductive articles from silicon powder by sintering the powder while it is being pressed or sedimented in a mould at a temperature of 1150.degree.-1250.degree. C. in an inert atmosphere and in the presence of boron oxide, optionally followed by adding a further amount of boron into the sintered shaped article. The boron oxide, which is used in an amount of 0.1-11% by weight, based on the silicon powder, can be added in the form of an aqueous solution.
