Description
technical field [0001] The invention belongs to the field of material preparation equipment and relates to a reaction device. technical background [0002] With the continuous expansion of the application range of functional materials, composite materials, and ceramic materials in various industries, the requirements for the microstructure of materials are getting higher and higher. How to prepare ultra-fine, high-purity, uniform size, regular shape, and surface properties Excellent powder materials have become the focus of attention. As a technique for preparing ultrafine particles, spray pyrolysis has attracted the attention of researchers in the fields of materials, chemical engineering, aerosols, and superconductivity. Israeli Aman first prepared MgO by spray pyrolysis in 1956. In the 1970s, Austrian Ruthner first applied this technology to industrial production. After decades of development, it was widely used in the preparation of metal materials and inorganic non-met...
