Zinc oxide varistor dielectric material and preparation method thereof
The invention relates to a zinc oxide varistor dielectric material, which is prepared from ZnO, Sb2O3, Bi2O3, a Mn-containing compound, a Co-containing compound, Ni2O3, In2O3, silver glass powder and Al (NO3) 3.9 H2O. The mole number of Sb2O3 accounts for 0.8%-1.05% of the mole number of ZnO, the mole number of Bi2O3 accounts for 0.55%-0.70% of the mole number of ZnO, the mole number of Mn ions in the Mn-containing compound accounts for 0.52%-0.84% of the mole number of ZnO, the mole number of Co ions in the Co-containing compound accounts for 0.90%-1.38% of the mole number of ZnO, the mole number of Ni2O3 accounts for 0.20%-0.40% of the mole number of ZnO, and the mole number of In2O3 accounts for 0.007%-0.010% of the mole number of ZnO; the weight of the silver glass powder is 0.08-0.1% of that of ZnO, and the weight of Al (NO3) 3.9 H2O is 0.025-0.030% of that of ZnO. The invention also provides a preparation method of the zinc oxide varistor dielectric material. The zinc oxide varistor dielectric material is good in pulse impact resistance, low in residual voltage under large current, capable of being sintered at medium and low temperatures and low in energy consumption.
