High Electromechanical Coupling Factor: LGS crystal has an electromechanical coupling factor of 15.8%, higher than that of quartz crystal. This indicates its high efficiency in converting electrical energy into mechanical energy.

Lower Propagation Velocities: The surface acoustic wave propagation velocity in LGS crystal is much lower compared to other materials. This allows for smaller geometrical dimensions of filters operating at the same center frequency, which aligns with the trend towards denser integration of modern electronics and reduces production costs.

High Thermal Stability: Devices made from langasite crystal can operate at high temperatures up to 900°C, making them suitable for high-temperature applications.

Applications: Surface Acoustic Wave (SAW) Devices, Bulk Acoustic Wave (BAW) Devices, High-Temperature Applications, etc.
