Title:
SINTERED BODY FOR THERMISTOR ELEMENT AND ITS MANUFACTURING METHOD, AND TEMPERATURE SENSOR
Document Type and Number:
Japanese Patent JP3970851
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a sintered body for a thermistor element which has excellent temperature detection performance in a wider temperature range of about 100-1,000 °C and in which variations of a resistance value before and after a thermal history are small, and a temperature sensor.
SOLUTION: The sintered body for the thermistor element includes Y, Sr, Fe, Mn, Al, Si, and O, and it does not include Cr. When the number of mols of Sr is set as X, the number of the mols of Y as 1-x, the number of the mols of Mn as y, the number of the mols of Al as z, and the number of the mols of Fe as 1-y-z, it is within respective ranges of 0.090≤x≤0.178, 0.090≤y≤0.178, z≥0.275, and 1-y-z≥0.025.
