A piezo-electric porcelain constituent and a manufacturing method for the same
Document Type and Number:
Japanese Patent JP5990760
Kind Code:
B2
Abstract:
A piezoceramic composition comprises, as the main phase, a crystalline phase of a perovskite structure signified as formula ABO3, with Element A consisting of one or more elements selected from among K (potassium), Na (sodium) and Li (lithium) and with Element B consisting of one or more elements selected from among Nb (niobium), Ta (tantalum) and Sb (antimony), with Elements A and B comprising other elements as additives. An X-ray diffraction profile of crushed particles of the piezoceramic composition that are 10 μm or less in diameter has a diffraction peak indicating the presence of the main (single) phase as well as a heterogeneous phase of a crystalline structure signified as formula AsBtOu (s
