Lead zirconate titanate with iron/tungstein doping, method of producing a piezoceramic material with the lead zirconate titanate, and use of the piezoceramic material
Abstract:
A piezoceramic composition has a nominal empirical formula of Pb1−aREbAEc[ZrxTiy(FefWw)z]O3. RE is a rare earth metal with a fraction b and AE is an alkaline earth metal with a fraction c. Iron is present with an iron fraction f·z, and tungsten with a tungsten fraction w·z. In addition, the following relationships apply: a 0; w>0; 0.1=f/w=5; x>0; y>0; z>0 and x+y+z=1. A method of producing a piezoceramic material using the piezoceramic composition has the steps: a) provision of a green ceramic body with the piezoceramic composition, and b) heat treatment of the green body, a piezoceramic of the piezoceramic material being produced from the piezoceramic composition. The heat treatment encompasses calcining and/or sintering. The piezoceramic composition undergoes compaction at below 1000° C. Metals which melt at low temperature (such as silver or a silver-palladium alloy with a low palladium content, for example) can therefore be sintered together with the piezoceramic composition.
Abstract(Chinese):

压电陶瓷组合物具有Pb1-aREbAEc [ZrxTiy（FefWw）z] O3的名义经验式。 RE是具有级分b的稀土金属，AE是具有级分c的碱土金属。 铁存在铁分数f·z，钨与钨分数w·z存在。 此外，以下关系适用：a <1; 0 = b = 0.15; 0 = c = 0.5; f> 0; w> 0; 0.1 = f / w = 5; x> 0; y> 0; z> 0且x + y + z = 1。 使用压电陶瓷组合物制造压电陶瓷材料的方法具有以下步骤：a）使用压电陶瓷组合物提供生坯陶瓷体，以及b）生坯体的热处理，由压电陶瓷组合物制备的压电陶瓷材料的压电陶瓷 。 热处理包括煅烧和/或烧结。 压电陶瓷组合物在低于1000℃下进行压实。因此，可以与压电陶瓷组合物一起烧结在低温熔化的金属（例如银或具有低钯含量的银钯合金）。
