FIELD: catalyst for production of ethylene oxide. SUBSTANCE: catalyst for production of ethylene oxide contains silver and one or several promoters from alkali metal applied to carrier whose crushing strength is at least 2-3 kg and definite bulk density of at least 0.48 kg/l, which includes the first and second components of alpha-aluminum oxide. In this case, the first component of alpha-aluminum oxide in the form of particles having average size of crystallites of 0.4-4 mcm amounts from 95 to 40% of total weight of alpha-aluminum oxide in carrier; the second component of alpha-aluminum oxide produced in situ by sol-gel process makes up the remaining amount of alpha-aluminum oxide in carrier. Titanium oxide is optionally added to carrier. The invention also covers description of the method of producing carrier of the catalyst. Catalyst have unique carrier from aluminum oxide . EFFECT: improved selectivity and/or activity. 17 cl, 6 tbl
