Abstract

An agglomerated mixture includes 30-95% by weight of highly dispersed metal oxides produced by flame hydrolysis and 5-70% by weight of inorganic opacifiers that have at least one absorption maximum in the range between 1.5 and 10 .mu.m, selected from the group consisting of inorganic oxides and mixed oxides, carbides and nitrides. The invention also relates to a process of manufacturing the mixtures and to their use as heat-insulating material and the like.
