Abstract
A reaction-formed moulded ceramic body containing mullite is described which is obtainable by heat treating a body moulded from a finely dispersed powder mixture of aluminium, Al.sub.2 O.sub.3 and a material containing Si in an atmosphere containing oxygen. Due to their properties, in particular their low shrinkage of 0 to 4% on average, the moulded bodies are very well suited for use as wear-resistant and/or high temperature-resistant components in the construction of machines, apparatuses and motors, as a cutting tool, as a component for bearings and/or seals and as a functional part in electronic instruments.
