Control of Varistor Voltage by Grain-size Control of Bi-added ZnO Varistors
IOP Conference Series: Materials Science and Engineering, 2011 Relationship between the grain size of ZnO and the amounts of Bi and Sb for Bi-Ba-Sb-Co-Mn-added ZnO was investigated. The amount of Bi at which the grain size of ZnO became the maximum shifted to the notably larger one by adding small amount of Sb such as 0.01 mol%.
