| Abstract: | The effect of some factors (such as bulding grain. sintering technics, raw and processed materials, adulterants)on the relibility of NTCR applied in suppressing surge current is discussed in this paper. According to the experiment result, the abating ratio can be dropped to 8ppm from 100ppm by selecting proper grains. sinterring temperature. high quality raw and processed materials, and doping small amount of SiO2,. Cr2O3,. Sb2O3. |
