Preparation method of negative temperature coefficient thermistor material Sr8Ti7S21
The invention discloses a preparation method of a negative temperature coefficient thermistor material Sr8Ti7S21, which is used for solving the problems that the current thermistor material is difficult to prepare and relatively high in resistance, and the preparation method comprises the following steps: taking SrTiO3 powder as a raw material, and carrying out vulcanization reaction to obtain Sr8Ti7S21 powder; the obtained Sr8Ti7S21 powder is subjected to hot pressing, and a Sr8Ti7S21 blank is obtained; and carrying out high-temperature sintering on the obtained Sr8Ti7S21 blank, so as to obtain the negative temperature coefficient thermistor material Sr8Ti7S21. Based on different sintering temperatures, the negative temperature coefficient thermistor Sr8Ti7S21 with the room temperature resistivity of 0.7-15.9 omega.cm can be obtained, and the negative temperature coefficient thermistor Sr8Ti7S21 shows a good resistance-temperature incidence relation and has a good application prospect in the fields of temperature detection and the like.
