DEVICE FOR CREATION OF EXTRA HIGH PRESSURE AND TEMPERATURE Russian patent published in 2015 - IPC B01J3/06 

FIELD: machine building.

SUBSTANCE: device contains coaxially installed matrices 1 and 1', on looking each other end surfaces of them central cavities 7 and 7' are made, these cavities are limited by internal ring shoulders A and peripheral shoulders B. Between the matrices 1 and 1' in the device the container 3 with sample and heater 4 is installed. Container 3 is enclosed by ring 5 out of plastic material. To increase efficiency of the substance compression and holding processes in central reaction volume of the device the internal shoulders A of matrices 1 and 1' are made truncated in the horizontal plane, at that between width w of truncated surface of shoulder A and its height h₁ relatively bottom of the central cavity 7 and 7' in matrix the ratio is met: 0.7h₁<w<0.9h₁. The peripheral shoulders B of matrices 1 and 1' are made with height h₂ relatively to bottom of central cavity 7 and 7' in comparison with height of internal shoulders h₁ meeting ratios h₁<h₂≤1.2h₂, and between peripheral shoulders B a stop ring 6 is located, it limits approach of matrices 1 and 1' at final stage of pressure creation in the central volume of the device.

EFFECT: increased strength of the device, and its capacity during operation.
