The Curie Temperature For a given ferromagnetic material the long range order abruptly disappears at a certain temperature which is called the Curie temperature for the material. The Curie temperature of iron is about 1043 K. The Curie temperature gives an idea of the amount of energy it takes to break up the long-range ordering in the material.

Because of the low temperature (-254.2/-425.5 ºC/ºF) at which the ferromagnetism of neodymium metal disappears (or called Curie temperature), a certain amount of iron is present ina Neodymium Block Magnet in order to increase the Curie temperature well above room temperature. PTC Thermistor Resistor Types Resistor GuideThe Curie temperature is most of the time defined as the temperature at which the resistance is twice the value of the minimum resistance. Minimum resistance (R min) The minimum resistance of a PTC thermistor is the lowest resistance that can be measured on a switched type PTC thermistor, as seen on the R-T curve. It is the point on the curve curie temp of x7 plate Piezo Basics - CTSMaximum temperature. Piezoelectric materials should be used below the Curie temperature to avoid depoling. Rule of thumb is half Curie temperature. If the temperature were to that raise close to the Curie temperature or above, it will cause the piezoelectric material to become partially or completely depoled and severely degrade the performance.
