MANUFACTURE OF THERMISTOR CERAMIC

摘要

PURPOSE: To provide thermistor ceramic which is composed of a manganese- nickel-copper oxide and shows a small rate of resistance change under a high- temperature, high-humidity condition and the element assembly of which has a high mechanical strength. CONSTITUTION: The thermistor ceramic is manufactured in such a way that at least aluminum oxide or zirconium oxide is added to a manganese-nickel- copper oxide at a rate of 0.1-20.0wt.% at the time of grinding the oxide after calcination and the mixed powder is molded and burnt.
