Abstract :

La₃Ga_5.5Ta_0.5O₁₄ (LGT) crystals could be useful for frequency control applications because the combination of electromechanical coupling constant and thermal stability is very promising. Y-cut directly have zero value of first order temperature coefficient. Second order temperature coefficient is near of La₃Ga₃SiO₁₄ (LGS) figure. The present paper is devoted to measurements of elastic, piezoelectric and dielectric properties of LGT at room temperature and temperature dependencies of some sound mode velocities
