    摘要: A method for producing ceramic components, includes providing a dispersing agent comprising at least one first and one second powder fraction of an oxide ceramic, and a third powder fraction of an inter-metallic compound mixed in a liquid. The first powder fraction comprises a nanoscale particle fraction with particle sizes ranging from about 2 nm to 200 nm and functions as a binder. The second powder fraction comprises a sintering additive. The share of the third powder fraction, relative to the sum of all powder fractions, has a volume share of between about 50% and about 95%. The method further includes forming a green body with aid of precipitation by electrophoresis from the mixture, the precipitation by electrophoresis of the powder fractions occurring simultaneously. The green body is then sintered in an oxidizing atmosphere to form a ceramic component.
