Abstract

The invention discloses a dielectric ceramic body capable of resisting instantaneous voltage. The dielectric ceramic body contains a first main component BaTio3 and a second component ABO3 which have mole numbers which accord to a formula ratio (A=Ba,Sr,Ca; B=Zr,Ti) of a general formula (100-x) BaTiO3-x ABO3, wherein the second component ABO3 is preferable SrZrO3 or CaZrO3, and at least one sub-component is added to perform sintering. The dielectric ceramic body thus formed contains a composite phase structure which has cubic crystal and rhombohedral crystal in co-existence. What's more, a capacitor which is formed by the dielectric ceramic body can resist dielectric damage effects caused by instantaneous potential ascending power, and the temperature capacitor exhibits in accordance to EIA-X7R capacitor regulations.

Description

【Technical field】 [0001] The invention provides a dielectric ceramic body resistant to instantaneous high voltage. In addition to having an anti-oxidation and reduction effect on base metal manufacturing processes, the dielectric ceramic body can even withstand high voltage impacts caused by instantaneous potential difference changes, and it is prepared The multilayer ceramic capacitors also have excellent capacitance stability against temperature and meet the capacitor specification of EIA-X7R. 【Background technique】 [0002] According to the Electronic Industries Association (EIA) of the United States, capacitors are classified as Class I temperature compensation capacitors and Class II medium and high dielectric value capacitors (such as figure 1 shown). If the capacitor is classified as Case II, it has a relatively high dielectric constant (Dielectric constant, K), and can even be easily made into a capacitor with high capacitance. However, when any type of capacitor i...
