Abstract

A design for high pressure/high temperature apparatus and reaction cell to achieve .about.30 GPa pressure in .about.1 cm volume and .about.100 GPa pressure in .about.1 mm volumes and 20-5000.degree. C. temperatures in a static regime. The device includes profiled anvils (28) action on a reaction cell (14, 16) containing the material (26) to be processed. The reaction cell includes a heater (18) surrounded by insulating layers and screens. Surrounding the anvils are cylindrical inserts and supporting rings (30-48) whose hardness increases towards the reaction cell. These volumes may be increased considerably if applications require it, making use of presses that have larger loading force capability, larger frames and using larger anvils.

Apparatus for processing materials at high temperatures and pressures

Patent Afimiwala, Kirsh; Zeng, Larry

An apparatus for processing materials at high temperatures comprises a high strength enclosure; a plurality of high strength radial segments disposed adjacent to and radially inward from the high strength enclosure; a liner disposed adjacent to and radially inward from the radical segments; a chamber defined interior to the liner; a heating device disposed within the chamber; and a capsule disposed within the chamber, the capsule configured to hold a supercritical fluid. The apparatus may be used for growing crystals, e.g., GaN, under high temperature and pressure conditions.

Method and apparatus for simultaneously measuring temperature and pressure

Patent Hirschfeld, Tomas B [Livermore, CA]; Haugen, Gilbert R [Pleasanton, CA]

Method and apparatus are provided for simultaneously measuring temperature and pressure in a class of crystalline materials having anisotropic thermal coefficients and having a coefficient of linear compression along the crystalline c-axis substantially the same as those perpendicular thereto. Temperature is determined by monitoring the fluorescence half life of a probe of such crystalline material, e.g., ruby. Pressure is determined by monitoring at least one other fluorescent property of the probe that depends on pressure and/or temperature, e.g., absolute fluorescent intensity or frequency shifts of fluorescent emission lines.

Apparatus and method for enhanced chemical processing in high pressure and atmospheric plasmas produced by high frequency electromagnetic waves

Patent Efthimion, Philip C [Bedminister, NJ]; Helfritch, Dennis J [Flemington, NJ]

An apparatus and method for creating high temperature plasmas for enhanced chemical processing of gaseous fluids, toxic chemicals, and the like, at a wide range of pressures, especially at atmospheric and high pressures includes an electro-magnetic resonator cavity, preferably a reentrant cavity, and a wave guiding structure which connects an electro-magnetic source to the cavity. The cavity includes an intake port and an exhaust port, each having apertures in the conductive walls of the cavity sufficient for the intake of the gaseous fluids and for the discharge of the processed gaseous fluids. The apertures are sufficiently small to prevent themore » « less

Apparatus and method for high temperature viscosity and temperature measurements

Patent Balasubramaniam, Krishnan; Shah, Vimal; Costley, R. Daniel; ...

A probe for measuring the viscosity and/or temperature of high temperature liquids, such as molten metals, glass and similar materials comprises a rod which is an acoustical waveguide through which a transducer emits an ultrasonic signal through one end of the probe, and which is reflected from (a) a notch or slit or an interface between two materials of the probe and (b) from the other end of the probe which is in contact with the hot liquid or hot melt, and is detected by the same transducer at the signal emission end. To avoid the harmful effects of introducingmore » « less
