Abstract (en)

A novel thermistor includes a semiconductor ceramic comprising an oxide spinel containing Mn, Ni and In. Preferably, the oxide spinel has the composition Mn2.33-xInxNi0.67O4, where x = 0.05 to 0.75, preferably 0.5 to 0.66, especially 0.58 plus or minus 0.02.

Abstract (de)

Ein Thermistor mit einer Halbleiterkeramik mit einem Oxid-Spinell, der die Elemente Mangan, Nickel und Indium enthält, ist thermisch stabil und zeichnet sich weiterhin durch hohe Werte für den spezifischen Widerstand und den B-Wert aus. <IMAGE>
