<P>PROBLEM TO BE SOLVED: To provide a barium titanate-based piezoelectric ceramic capable of low-temperature firing without impairing the piezoelectric characteristic. <P>SOLUTION: Barium titanate powder which is a main component and has an average particle diameter of 0.05-0.10 μm, at least one kind of lithium oxide powder selected from lithium carbonate or lithium oxide as a first accessory component and vanadium pentoxide powder as a second accessory component are used as starting materials, and x pts.wt. of lithium oxide powder in terms of lithium oxide and y pts.wt. of vanadium pentoxide powder (wherein 0.040≤x≤0.081; 0.02≤y≤0.10) are added to 100 pts.wt of the main component and fired in a temperature range of 1,000-1,200°C. <P>COPYRIGHT: (C)2010,JPO&INPIT |
