Abstract
THE preparation and properties of chromic oxide–chromium cermets have been examined as part of a general investigation into the possibility of preparing metal–ceramic mixtures (‘cermets’) by partial reduction of refractory oxides. The method consists of pressing a mixture of chromic oxide and carbon, both in the finely divided state, into compacts and sintering to temperatures in the range 1,400°–1,600° C in a vacuum of circa 10−4 mm mercury. The amount of carbon is calculated to give 1–10 per cent metallic chromium in the sintered body.
