Lithium Tantalate (LT, LiTaO3) tau muaj zog, raws li pom ib cov khoom siv uas nyob rau hauv daim ntaub ntawv Electro-kho qhov muag thiab Acousto-kho qhov muag. Tej no yuav ua tau: nto acoustic yoj pab kiag li lawm, tej acoustic yoj pab kiag li lawm, piezo-fais transducers thiab piezoelectric sensors.

Pom daim ntaub ntawv
Tus 36° thiab 42 ° to thiab cov Lithium Tantalate tau qhia ntau los tu rau lub telecommunications txawb xov tooj handset lag luam ntawm frequencies los ntawm 800 rau 2100 MHz. Cov naiskhu qhia kev optimized bandwidth / zoo poob lag luam tawm tshem tawm hauv kev kawm ntawv thiab dominating tus expanding puas mobile handset muag.
Rau sab bandwidth, ntau dua uas lim lwm naiskhu xws li tus 112° rotated ntuag pom zoo cog lus thiab yog zoo zus rau cov kis ntawm Quartz (Ultra nqaim qhab) thiab cov ua qauv 36/42 ° (wideband).
Lithium niobate thiab lithium tantalate yuav los nrog ntau zog rau kev siv differing, txug tej yaam kev tshawb kawm thiab kev ntau lawm. Piv txwv li wafers dawb pyroelectric raws, 4"(hli 100), orientation 36 ° lossis 42°.
