Patent ID: 7767608

Claim:
A dielectric ceramic-forming composition obtained by wet process, comprising a perovskite (ABO 3 ) ceramic material powder having an average particle size of 0.01 to 0.5 μm and a BET specific surface area greater than 2 m 2 /g and a glass powder having an average particle size of 0.1 to 5 μm, which dielectric ceramic-forming composition is obtained by wet-mixing said perovskite ceramic material powder and said glass powder in a solvent solution of one or more solvents selected from the group consisting of methanol, ethanol, propanol, butanol, toluene, xylene, acetone, methylene chloride, ethyl acetate, dimethyl formamide, and diethyl ether, wherein the content of the glass powder is 3 to 12 percent by weight; wherein the glass powder is a glass powder containing B 2 O 3 ; and wherein the content of the B 2 O 3 is 10-35% by weight.
