商用ZnO基压敏电阻器的高分辨率电子显微镜显示,在所有三粒和四粒交界处都发现了富含Bi的晶间相,并且大多数ZnO晶粒并不像之前认为的那样被氧化物阻隔膜包围。
High‐resolution electron microscopy of a commerical ZnO‐based varistor reveals that the Bi‐rich intergranular phase is found at all three‐ and four‐grain junctions and that the majority of the ZnO grains are not surrounded by an oxide‐barrier film as previously believed.
