"A new varistor system based on terbium oxide is introduced in this paper," scientists in Chengdu, People's Republic of China report.
"The ceramic samples were prepared using the standard ceramic method and sintered in air at 1300 degrees C for 2 h. From the I-V measurements, the samples exhibit varistor action with the nonlinear coefficient alpha = 3.9 and the breakdown voltage E-b = 40 V mm(-1) and possess excellent electrical stability up to 70 degrees C. X-ray diffraction reveals that the ceramic is a single phase structure. It is proposed that the varistor action can be attributed to the adsorbed oxygen on the grain surfaces," wrote T.Y. Li and colleagues, ...
