Abstract

The invention discloses a semiconducting glass glaze capable of significantly improving the annihilation breakdown performance of an ultra-high voltage ceramic capacitor and a method for preparing and using the semiconducting glass glaze slurry including ceramic powder, glass glaze powder, terpineol and ethyl alcohol. Base cellulose, wherein the weight of glass glaze powder is 2.1-2,8 times the weight of ceramic powder; the weight of terpineol is 28%-31% of the weight of glass glaze powder; the weight of ethyl cellulose is glass glaze powder 5%-6% by weight; ceramic powder is made of 79.2%-91.5% SnO2 powder and 8.5%-20.8% Sb2O3 through sintering, grinding and sieving; glass glaze powder is made of 66%- 86% PbO powder, 3%-9% B2O3 powder and 11%-25% SiO2 powder are prepared by sintering, grinding and sieving. When preparing a high-voltage ceramic capacitor, it includes coating and firing the above-mentioned semiconductor glass glaze slurry. After coating and firing the semiconductor glass glaze slurry, the electrical breakdown field strength of the high-voltage ceramic capacitor can be significantly improved.

Description

technical field

[0001] The invention relates to a semiconductor glass glaze slurry, a high-voltage ceramic capacitor using the semiconductor glass glaze slurry, and a method for manufacturing a high-voltage ceramic capacitor. Background technique

[0002] At present, the anti-electrical breakdown field strength of existing domestic high-voltage and ultra-high-voltage ceramic capacitors (electrical breakdown field strength = breakdown voltage / product thickness) is 3-6KVDC / mm, and it is: the thinner the product, the better the anti-electrical breakdown field strength. The lower the field strength. The reason is mainly that under the premise that the product formula and preparation process are normal, the only effective way to increase the breakdown field strength of the product is to greatly increase the thickness of the product.

[0003] However, from the failure products of the above-mentioned products after the electric breakdown field strength test, it is easy to find tha...
