A composite material having a first phase includes an aluminum oxide proportion of at least 65% by volume and a second phase comprising a zirconium proportion of 10 to 35% by volume. The zirconium is present as zirconium oxide. The aluminum oxide is a ceramic matrix and the zirconium oxide is dispersed therein. From 90 to 99% of the zirconium oxide is present in the tetragonal phase. A chemical stabilizer for stabilizing the tetragonal phase of the zirconium oxide is also present. The total content of chemical stabilizer is &#x3c;0.2 mol % relative to the zirconium oxide content.

Ceramic composite material consisting of aluminium oxide and zirconium oxide as main constitutents

A composite material consisting of aluminium oxide as a ceramic matrix and zirconium oxide dispersed therein. A method for the production thereof, components containing the composite and methods of using the same are also provided.

An insertion instrument for hip endoprosthetics for inserting socket inserts into endoprosthetic hip sockets having holding claws which are connected to a substantially ring-shaped support element through spring elements, wherein the insertion instrument can be placed on the socket insert and can be connected to said socket insert through the holding claws. In order for the user to receive direct palpatory information about the events in the operation areas and to not suffer a perceived loss of control, it is proposed that the support element surround a freely accessible, substantially circular effective insertion area, the center point of which is located on the longitudinal axis of the insertion instrument.

Insertion instrument for inserting socket inserts into the spherical recesses of hip sockets

A ceramic heating element arrangement in which a ceramic heating element made of SiC having electrical NTC (negative temperature coefficient) properties is provided for a circuit. At least one segment is provided in the circuit, whose resistance saturates at least quasi-asymptotically at the current flow required for a desired heat development.
