Abstract
The prospects of lithium-niobate-tantalate solid solutions (LiNb1-xTaxO3, LNT) for high-temperature sensors and actuators are presented from a physical and materials science perspective. The focus lies on defect mechanisms that are relevant for the acoustic losses that determine potential applications of such crystals at high temperatures. Further, tailoring of the materials properties by variation of the niobium- tantalum ratio is demonstrated.
