The application of microwaves in laboratories can be divided into two categories based on the purpose of microwave heating. One category is physical processes, which use microwave heating technology to heat, dry, concentrate and other process conditions on target materials, with the aim of serving as a means of material processing; Another type is chemical processes, which use microwave heating technology to catalyze, synthesize, decompose, sinter and other process conditions on the target material as a means of synthesizing and decomposing materials. The general requirements for laboratory microwave ovens in two types of processes are temperature, power, and time control to match the user's material system.
