Zusammenfassung:Improved catalyst is made by including in a grind charge of cupreous particulates a small proportion of hydrated refractory metal oxide such as hydrated alumina. Said grind charge contains a major proportion of cuprous and cupric oxides, a minor proportion of elemental copper, and up to about 10% of promoter material. Such charge is subjected to high energy comminution with concomitant crystal lattice distortion. The catalyst is useful for the production of alkyl and aryl halosilanes.
