Fomos-Materials

Fomos-Materials company is one of the worldwide leaders in producing and supplying of piezocrystals and piezosubstrates - langasite, langatate and others. Piezoelectric materials and devices - filters, resonators, sensors, langasite wafers, langatate sensor blanks.

Langasite (LGS) is a unique piezoelectric crystal, possessing unique physical properties that can be used in piezoelectronics.
Langasite as compared to Quartz, Lithium niobate and Lithium tantalate has lesser anisotropy of longitudinal expansion coefficients that is important for high temperature application.
LGS substrates are used in producing of SAW and BAW filters, resonators and other piezodevices.

Sensors of langasite can be fabricated as bulk wave (BAW) or SAW devices. Tuning fork style sensors allow a very small size. The sensors can be used to measure various phisical parameters such as temperature, force, pressure, viscosity, flow, micro-mass etc. up to temperatures of 900 C or even more.
