Title:
HEAT CONDUCTOR, ESPECIALLY FOR A SENSOR, AND METHOD FOR PRODUCING SUCH A HEAT CONDUCTOR
Document Type and Number:
WIPO Patent Application WO2001004915
Kind Code:
A3
Abstract:
The invention relates to a heat conductor, especially for a sensor for detecting at least one gas component in the exhaust gases of internal combustion engines. Said heat conductor consists of a cermet that contains platinum and at least one metal oxide. The invention further relates to a method for producing a heat conductor for a sensor for detecting an oxygen concentration, especially in the exhaust gases of internal combustion engines. A mass that makes up the heat conductor and that comprises a platinum powder and a metal oxide powder is applied on a ceramic film and is sintered. According to the invention, at least two further precious metals are added to the cermet.
