LANTHAN GALLIUM SILIKATSCHEIBE UND DEREN HERSTELLUNG

摘要

The invention relates to the field of electronics and can be used in acoustic electronic frequency-selective devices in surface acoustic waves (SAW) and volumetric acoustic waves. The purpose of the invention is the formulation of an industrial process to develop stoichiometrically structured monocrystals of lanthalum gallium silicate, of no less than 75 mm in diameter and greater than 3,5 kg in weight, along a direction of &lang& 01.1 &rang& +/-3 DEG . The discs are cut out at a 90 DEG angle with respect to the lengthwise axis, thereby ensuring that the value of the frequency temperature coefficient is zero.
