ABSTRACT:
The present invention provides a zirconium oxide-containing ceramic formed body, wherein it is also free from amorphous phases on the grain boundaries and triple points, displays a shrinkage of less than 5% in comparison with its green body and is obtainable by reaction sintering of a green body, said ceramic formed body being formed from a mechanically alloyed mixture which contains or consists of at least 1% by volume zirconium metal powder and at least 20% by volume of one or more metallic powders selected from the elements magnesium, aluminum, copper, selenium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, zinc, strontium, yttrium, niobium, cerium, hafnium and tantalum, as well as the oxides thereof and zirconium oxide, sodium oxide, potassium oxide and lithium oxide.
The present invention also provides a process for the production of this ceramic formed body which can be used as a construction element in machines and apparatus, in electronics as a functional element and as a solid body electrolyte.
