Thermal sensitive ceramic double-parameter temperature measuring material and preparation method of thermal sensitive ceramic double-parameter temperature measuring material
The invention relates to a thermal sensitive ceramic double-parameter temperature measuring material and a preparation method of the thermal sensitive ceramic double-parameter temperature measuring material. Through being metered by the content in percentage by mass, the thermal sensitive ceramic double-parameter temperature measuring material comprises the following ingredients including 70 percent to 90 percent of first composition and 10 percent to 30 percent of second composition, wherein a chemical composition general formula of the first composition is Mg(Fe<1-y>Aly)xW<1-05x>O4, wherein the x is greater than or equal to 0.1 but smaller than or equal to 0.4, and the y is greater than or equal to 0.1 but smaller than or equal to 0.5; a chemical composition general formula of the second composition is Mg<1.8-b>ZnbSiO<3.8>, and the b is greater than or equal to 0.1 but smaller than or equal to 0.3. An unexpected effect is achieved; meanwhile, materials of a negative temperature coefficient thermistor and a positive dielectric constant temperature coefficient thermal sensitive capacitor are simultaneously used; the negative temperature coefficient thermistor and the positive dielectric constant temperature coefficient thermal sensitive capacitor are used for temperature measurement in a segmented way; an temperature measuring interval is expanded; the thermal sensitive ceramic double-parameter temperature measuring material is suitable for the precise temperature measurement in the interval being 0 to 1100 DEG C, and can be used for preparing high-sensitivity and wide-temperature-interval thermal sensitive temperature sensors; meanwhile, by adopting the thermal sensitive ceramic material, a temperature threshold point can be converted from thermistor temperature measurement into thermal sensitive capacitor temperature measurement to serve as a temperature switch threshold, and the thermal sensitive ceramic double-parameter temperature measuring material is suitable for being used as temperature switches.
