PROBLEM TO BE SOLVED : To provide a voltage non-linear resistor porcelain that can achieve an excellent varistor characteristic, particularly excellent ESD characteristic resistance, and is further used for a component such as an on-vehicle component or the like to which high moisture resistance is required.SOLUTION : A voltage non-linear resistor porcelain contains oxide of Zn, oxide of Co, oxide of R (specific rare earth), oxide of Cr, oxide of M1 (Ca, Sr), oxide of M2 (Al, Ga, In) and strontium titanate. When the content of oxide of Zn is set to 100 parts by mol in terms of Zn, the content of oxide of Co ranges from 0.30 to 10 parts by mol in terms of Co, the content of oxide of R ranges from 0.10 to 10 parts by mol in terms of R, the content of oxide of Cr ranges from 0.01 to 2 parts by mol in terms of Cr, the content of oxide of M1 ranges from 0.10 to 5 parts by mole in terms of M1, the content of oxide of M2 ranges from 0.0005 to 5 parts by mol in terms of M2, and the content of strontium titanate ranges from 0.10 to 5 parts by mol in terms of SrTiO3.SELECTED DRAWING : NoneCOPYRIGHT : (C)2017, JPO&INPIT |
