| titleOfInvention | METHOD FOR PRODUCING SINTERING CERAMICS FOR HIGH ACCURACY THERMISTORS |
| abstract | The invention relates to a method for producing a sintered ceramic for high-precision thermistors. A method for producing high-precision thermistors is described. Previously known technical solutions are based on semiconducting oxides of the transition elements and their combinations in spinels and perovskites. Such multiphase systems require a differentiated adapted Reaktionsfuehrung, so that a sufficiently tightly tolerated assortment of long-term stable thermistors is available only through various forms of thermal and electrical aftertreatment and by classifying and separating. A reduction of this effort is possible by adding a PbO-GeO2 mixture using high-purity nickel and manganese oxide. The object of the invention is to compensate for the effect of impurities in the raw materials which inhibit the formation of a high-density sintered ceramic despite the addition of sintering aids. For this purpose, a method for producing a sintered ceramic for high-precision thermistors based on oxide semiconductors is used, characterized in that an advantageous precursor of the spinel compound by Überluehrung of nickel-manganese oxalate mixed crystals in a cubic defect spinel phase high Sinteraktivitaet in combination with additions of a PbO / GeO2 Mixture dense structures of high reproducibility of the Thermistoreigenschaften be obtained. |
