One of the first places among the synthetic minerals which can be applied in technology and industry belongs to the synthetic quartz due to its good piezoelectric and optical properties.

Synthetic types of piezoquartz raw materials are the indispensable crystalline materials for the production of unique perspective devices. The most common application of piezoelectric quartz is a piezoelectric resonator which is used as the basic element of the support technology products (Variable-frequency (VFO), temperature-compensated (TCXO), voltage-controlled (VCO), temperature-controlled (TCXO) oscillators, etc.). ZY-cut crystals are the most common crystals for use in the manufacture of quartz resonators and filters. ZX-cut crystals are used for the fabrication of surface acoustic wave delay lines on the basis of the large-scale ST-plates (300 mm in diameter). Piezoelectric quartz quality is determined by the International (IEC 758), Japanese (JIS C-6704) and Russian (OST 41-07-274-87) standards.
