Generation of High Pressure Oxygen and Synthesis of CoCrO4 with CrVO4 Type Structure

Abstract
A gas compressor was built for oxygen. For safety, water was chosen as a pressure transmitting medium. Oxygen gas compressed by high pressure water was led into a reactor. In the reactor, syntheses of oxides of transition metals were conducted in the range of temperature and pressure up to 600°C and 2000 bars. One of the successful results was the production of CoCrO4 with CrVO4 type structure.
