Crystalline Post-Quartz Phase in Silica at High Pressure

2001-9-25  $\ensuremath{\alpha}$-quartz, which has been reported to undergo pressure-induced amorphization, was found to transform to a monoclinic, crystalline phase when compressed to 45 GPa at room temperature in a close to hydrostatic, helium pressure medium. The x-ray powder diffraction data obtained could be indexed based on a monoclinic cell, and the intensities are in agreement with a

• Quartz- Great for high power (5+ KW of CW power) and high pressure or vacuum applications. Very low insertion loss windows and good VSWR performance over a wide variety of frequency ranges. • Ceramic- Very high power handling capabilities (10+ KW of CW power). Can be liquid cooled or have cooling fins added to window to aid in prolonged

RAYOTEK SIGHT GLASS WINDOWS HIGH PRESSURE,

2021-8-25  Rayotek has developed cutting-edge technologies for hermetically sealing sight windows, high pressure windows and vacuum windows with extremely high pressure capacities. In addition, our annular ring windows allow for non-interfering indirect ring lighting around a camera view windows which can be used in high pressure imaging applications.

Downhole Gauge for Pressure, Temperature, and Sensor

Highest-resolution, most-accurate pressure measurements available. You’ll get market-leading, consistently accurate pressure measurements with the Signature CQG crystal quartz gauge. By measuring pressure and temperature at a single point with a single quartz crystal, the Signature CQG gauge significantly reduces thermal effects.

Piezoelectric Pressure Sensors The Design Engineer's

The robustness, high frequency and rapid response time of piezoelectric pressure sensors means they can be used in a wide range of industrial and aerospace applications where they’ll be exposed to high temperatures and pressures. They are often used for measuring dynamic pressure, for example in turbulence, blast, and engine combustion.
