Title: Resistance heater with wire embedded in soft ceramic - is formed by preheating wire before finally sintering ceramic
Inventor: SARKANY ANDREAS DIPL CHEM DR
IPC: H05B3/18
Filed: 1976-05-20
Abstract: The resistance heater consists of resistance wire embedded in ceramic. The wire is embedded in the ceramic by preheating it sufficiently for it to sink into the unfired thermoplastic ceramic material. Once the wire has been completely enclosed by the soft ceramic the latter is sintered to give a rigid monolithic structure. The depth to which the wire sinks into the soft ceramic is controlled partly by varying the temp. of the wire. A ceramic is chosen that has a low sintering temp. and it may have a cylindrical shape. The wire is wound around the cylinder and sinks into it under the combined effects of heat and the coiling force.
