description The invention relates to a process for the preparation of a silver-containing catalyst suitable for the oxidation of ethylene to ethylene oxide which comprises a) mixing alumina with a tin compound and with an alkali metal compound, b) calcining the mixture to obtain an alkali-enriched and tin-containing alumina carrier, c) applying a silver compound to the alumina carrier and converting said silver compound to metallic silver. The catalyst has a high activity, a high selectivity combined with a very high stability.
