| Abstract: | ELECTRONIC COMPONENTS & MATERIALS (China), Vol 19, No 3, P 5 6 (Jun 2000) In Chinese In conventional formula, SrTiO 3 is prepared by solid phase reaction and MnO 2 is used as acceptor. To lower the varistor voltage, SrTiO 3 prepared by oxalate decomposition and acceptor of Li 2CO 3 are adopted instead of the formers respectively. The experiment results show that varistor voltage is effectively lowered, and dielectric properties improved also. (6 refs.) |
