Quartz Crystal Growing Vessels

EPSI, a world leader in custom-engineered high-pressure solutions, offers complete systems for hydrothermal growth of synthetic quartz. EPSI’s Quartz Crystal Growing Vessels are ideal for crystal growers that provide quartz components for a wide range of high-tech applications, including oscillators, frequency filters, telecommunications systems, microprocessors, color television, and time pieces. EPSI’s Quartz Crystal Growing Vessels are available for both high and medium pressure processes.

EPSI’s hydrothermal Quartz Crystal Growing takes place under constantly controlled temperature and pressure within EPSI’s forged Quartz Crystal Growing Vessels. Average cycle time is 24 to 36 days, depending on the size and quality of the crystals required. EPSI’s Quartz Crystal Growing Vessels are divided into a lower dissolving section and an upper growing section and each contains its own temperature control system. The total growth process is microprocessor controlled and may be entirely controlled by a central computer.

		EPSI’s Quartz Crystal Growing Vessels are available for laboratory-study or pilot processes. In addition, EPSI’s specialized engineers are available to provide advice and expertise on plant design, equipment, installation and start-up. Synthetic Piezoelectric Quartz EPSI supplies complete sets of synthetic quartz growth units. Quartz devices are used in a wide range of high-tech products such as oscillators and frequency filters for telecommunication and other electronic systems like TV and time pieces.

		Crystal Growth Hydrothermally crystal growth takes place under conditions of constantly controlled temperature and pressure, typically in the range of 380 to 400°C (720 to 750°F) and 15,000 to 30,000 psi (100 to 200 MPa). The entire process takes place within a forged high-pressure vessel. Production cycles can take from 3 weeks to more than 4 months, depending upon the quality and the size of crystals required. At present, two types of processes are used, high and medium pressure. EPSI supplies the special equipment for both. The total growth process is microprocessor controlled. An entire production plant can be controlled by a central computer of PC type. EPSI's specialized engineers are available to provide advice and expertise on plant design, equipment, installation and start up.
