Low-temperature preparation of refractory alloys

Low-temperature preparation of refractory alloys

ABSTRACT The escalating cost of energy has stimulated interest in the preparation of refractory and ceramic materials by low-temperature methods. Such methods are particularly attractive for


the preparation of catalysts because the products are more finely divided than those obtained from conventional solid-state reactions, and they are also of academic interest because they


provide the opportunity to examine some previously inaccessible low-temperature areas of phase diagrams. So far, interest has focused mainly on the synthesis of mixed metal oxides by the


ignition of precursors which have been precipitated from aqueous solution1 or freeze dried2, although platinum metal alloys have also been prepared, for example by the reduction of salts


which have been impregnated on a silica support3. I report here the low-temperature synthesis of the refractory alloy Mo–W by precipitation from aqueous solution followed by hydrogen


reduction. Access through your institution Buy or subscribe This is a preview of subscription content, access via your institution ACCESS OPTIONS Access through your institution Subscribe to
