CERAMIC COMPOSITION FOR A THERMISTOR TEMPERATURE SENSOR CAPABLE OF MEASURING TEMPERATURE THROUGH WIDE AREA OF -40 TO 1,000 DEG. CELSIUS, AND A THERMISTOR ELEMENT MANUFACTURED BY THE COMPOSITION

摘要

PURPOSE: A ceramic composition for a thermistor temperature sensor and a thermistor element manufactured by the composition are provided to have optimal resistance and low B integer by including Sb, Bi, and Sn.;CONSTITUTION: A ceramic composition for a thermistor temperature sensor comprises an element having a perovskite type crystal structure which is written as ABO3, Sn which is in the 4B family, and Sb and Bi which are in the 5B family. The A is composed of one or more elements among 3A group except 2A and LA. The B is composed of one or more elements among 4A, 5A, 6A, 7A, 8A, 2B and 3B which are transition metals. In the perovskite type crystal structure which is written as ABO3, the mixing ratio of A and B is 1:1. The element of A is M1, element of B is M2, and 4B(Sn) and 5B groups(Sb and Bi) are M3. The M1, M2 and M3 satisfy one or more following formulas: 0 Δ M1 Δ 1, 0 Δ M2+M3 Δ 1, and 0 Δ M3 Δ 0.6.;COPYRIGHT KIPO 2013
