与更传统的铁电材料相比，具有准同型相界(MPB)的钨青铜铁电材料具有许多增强的介电、压电和电光性能。介绍了几种MPB青铜系统的结构和铁电性能，包括烧结和热压陶瓷、外延薄膜和大块单晶的数据。其中包括三个以前没有被确定为形态相变的系统。讨论了这些MPB系统的潜在优点和局限性，以及它们在光学、压电或热释电器件应用中可能采用的合适的生长方法。
Tungsten bronze ferroelectrics which have a morphotropic phase boundary (MPB) can have a number of enhanced dielectric, piezoelectric, and electrooptic properties compared to more conventional ferroelectric materials. The structural and ferroelectric properties of several MPB bronze systems are presented, including data from sintered and hot-pressed ceramics, epitaxial thin films, and bulk single crystals. Included among these are three systems which had not been previously identified as morphotropic. The potential advantages and limitations of these MPB systems are discussed, along with considerations of the appropriate growth methods for their possible utilization in optical, piezoelectric, or pyroelectric device applications.
