Fomos-Materials company is one of the worldwide leaders in producing and supplying of piezocrystals and piezosubstrates.
The company has been founded in 1991 by the specialists of the former Soviet military-industrial complex, who had considerable experience in the development and production of piezoelectric devices. Our employees are well-qualified scientists, engineers and managers involved in investigating, producing and marketing innovative piezoelectric materials: langasite — lanthanum gallium silicate (LGS) and langatate — lanthanum gallium tantalate (LGT).
Fomos has a comprehensive technological cycle to grow crystals by the Czochralski method and provide a wide range of crystal products, including initial charge synthesis, crystal growth and further processing. Our production facilities are well equipped and staffed with experienced process engineers and operators.
Most of the unique crystal growth techniques developed by our researchers have got patent protection in the USA, Europe, Russia, China, Korea and Japan.
Fomos provides both standard and customized crystal products:
- Langasite (LGS) boules with <00.1>, <01.1> and <11.0> orientations;
- Langatate (LGT) boules with <00.1> and <11.0> orientations;
We supply LGS and LGT boules of 80-130 mm diameter, up to 120 mm length, up to 10000 g weight. - LGS/LGT precut blocks under customers' specifications;
- Langasite wafers for SAW application 76.2 mm (3-inch) and 100 mm (4-inch) diameter wafers with high acoustic homogeneity of various orientations to meet our customers' needs;
- Langasite blanks for BAW application (filters and resonators);
- Langatate sensor blanks for pressure, vibration, temperature sensors operating in a wide temperature range (up to 1000 °C).
