摘要:
A composition for electric material containing as a primary component zinc oxide. The composition further contains at least one of rare-earth elements in a range of 0.01 mol% to 3.0 mol% in terms of oxide thereof given by R 2 O 3 where R represents generally the rare-earth elements, and aluminum in a range of 0.0005 mol% to 0.005 mol% in terms of aluminum oxide given by Aℓ 2 O 3 . The composition is suited for manufacturing a resistance element whose varistor voltage can be increased over a whole current range without being accompanied with any appreciable degradation in flatness ratio of a voltage-versus-current characteristic.
