Abstract

The article presents a novel microwave reactor for hydrothermal synthesis of nanopowders. The reactor has a unique design of a process chamber, which, when used in conjunction with a batch control system, allows a highly efficient production of nanopowders. The design of the reactor together with the new principles of operation, structural materials and distribution of electromagnetic field are described. The article also presents a control system for the reactor, which allows for an automatic operation in the stop–flow mode, control of process pressure, continuous monitoring of process parameters and safe operation of the device. The device verification process is shown on the basis of the results of cobalt-doped zinc oxide nanopowder synthesis.
