Abstract

Multimetal oxide compositions of the formula I EQU [X.sup.1.sub.a X.sup.2.sub.b O.sub.x ].sub.p [X.sup.3.sub.c X.sup.4.sub.d X.sup.5.sub.e X.sup.6.sub.f X.sup.7.sub.g X.sup.2.sub.h O.sub.y ].sub.q(I) where PA1 X.sup.1 is bismuth, tellurium, antimony, tin and/or copper, PA1 X.sup.2 is molybdenum and/or tungsten, PA1 X.sup.3 is an alkali metal, thallium and/or samarium, PA1 X.sup.4 is an alkaline earth metal, nickel, cobalt, copper, manganese, zinc, tin, cadmium and/or mercury, PA1 X.sup.5 is iron, chromium, cerium and/or vanadium, PA1 X.sup.6 is phosphorus, arsenic, boron and/or antimony, PA1 X.sup.7 is a rare-earth metal, titanium, zirconium, niobium, tantalum, rhenium, ruthenium, rhodium, silver, gold, aluminum, gallium, indium, silicon, germanium, lead, thorium and/or uranium, PA1 a is from 0.01 to 8, PA1 b is from 0.1 to 30, PA1 c is from 0 to 4, PA1 d is from 0 to 20, PA1 e is from 0 to 20, PA1 f is from 0 to 6, PA1 g is from 0 to 15, PA1 h is from 8 to 16, x and y are numbers determined by the valency and frequency of the elements in I other than oxygen, and p and q are numbers whose ratio p/q is from 0.1 to 10, containing three-dimensional regions with a chemical composition …
