ABSTRACT OF THE DISCLOSURE Attrition resistant metal/oxygen compositions comprising the infusion and rection product of a re- fractory material characterized by a melting point of at least 1500°C, a mean particle size from about 10µm to about 200µm, and a fractional porosity of at least 0.2, and at least one metal oxide, or compound convertible by heat to such metal oxide, having a maximum mean parti- cle size of about 100µm, with the proviso that the refractory material/metal oxide mean particle size ratio is at least 2, which metal oxide is suscetible of under- going infusion and reaction with the refractory material upon being subjected to temperatures of at least 0.4Tm for a time sufficient to cause infusion and reaction between the metal oxide and the refractory material, wherein Tm is the melting point in °K of the refractory material, are useful in a wide variety of metal oxide- catalyzed reactions. The compositions are especially useful in reaction which involve reaction conditions of high stress, for example, vapor phase oxidations under fluidized bed conditions.
