Abstract

Crystal elements manufactured made of calcium tantalum gallium silicate single crystals (CTGS) operating in face shear mode were investigated. The frequency temperature characteristics of the rotated X-cut in high temperature range (up to 900°) were measured. The largest coupling factor close to 21.1% was found for (XYt) 9°-cut. It was shown that frequency temperature characteristic has a departure from a quadratic parabola which is atypical for langasite family crystals. The maximum value of the turnover temperature point 578° corresponds to (XYt) 9°-cut.
