摘要
The installation design and a chamber-reactor were proposed for laboratory-scale in situ X-Ray diffraction studies of solid phase transformations. Dynamics of phase transformations was studied for low-temperature copper chromite under the action of the reaction medium. Common and distinctive features of the behavior of low- and high-temperature copper chromites under redox conditions at the temperature below 300 degrees C were revealed.
