In this paper, the relationship between different formulation and resistivity and B value of Co-Mn transition metal oxides at a certain firing temperature is studied. The effect of quenching temperature on the resistivity and B value of the heat-sensitive material is investigated. The resistance-temperature characteristics and volt-ampere characteristics of the Co-Mn thermistor are discussed.
