Glass powder composition, glass glaze slurry, preparation method of glass glaze slurry, zinc oxide resistor disc and preparation method of zinc oxide resistor disc
The invention relates to the technical field of electrical ceramics, and discloses a glass powder composition, glass glaze slurry, a preparation method of the glass glaze slurry, a zinc oxide resistor disc and a preparation method of the zinc oxide resistor disc. Based on the total weight of the glass powder composition, the glass powder composition contains 65-78 wt% of Bi2O3, 10-20 wt% of ZnO, 1-8 wt% of CuO, 1.5-7.5 wt% of SiO2, 1-5 wt% of Al2O3, 1-4 wt% of Co2O3 and 4-10 wt% of B2O3, the content of the CuO is not higher than the content of the SiO2, the ratio of the content of the B2O3 to the content of the ZnO is smaller than or equal to 0.5, and the ratio of the content of the ZnO to the content of the B2O3 is smaller than or equal to 0.5. The sum of the contents of the Bi2O3, the ZnO and the B2O3 is not less than 85% of the total weight of the glass powder composition. The zinc oxide resistor disc provided by the invention can effectively play a role in preventing side flashover under current impact.
