1. According to variable factors effecting temperature of lithologic Curie point, a method used to assent accuracy of Curie surface is given.

2. This paper reviews the latest development of high Curie point PTC ceramics and low temperature sintering of PT C ceramics.

3. A new method for determining Curie point of ferromagnetic minerals is introduced in this article.

4. Most cast iron has curie point at about 1 040K except austenitic cast iron and white cast iron, their thermal diffusivity is the minimum there.

5. The failure rate of PTC (Positive Temperature Coefficient) thermistor increases with Curie Point (T_c) of determined PTC material.

6. One of the methods is attracted as it employs the magnetic material of low Curie point which is in response to the temperature change and thus able to de-ice automatically.

7. Magnetic properties indicate the transition from ferromagnetic to paramagnetic near the curie point, and exhibit the typical cluster glass characterization.

8. When the ball falls, the timing can be started; when the ball reaches the curie point, the magnetic iron can be absorbed and the timing can be stopped.

8. try its best to collect and create good sentences.

9. The transitional phase appeared when two ferroelectric powders with different Curie point were mixed and sintered together.

10. The transitional phase appeared when two ferroelectric powders with different Curie point were and sintered together.
