Abstract: Microwave technology has gained popularity in the chemical and energy industries due to its efficient thermal effects, but there is a risk of thermal runaway. To improve the microwave heating characteristics, a mode stirrer was introduced into the reaction kettle. The heating characteristics of mode stirrer materials (Aluminum, Alumina, Polyethylene and their combinations) and inner wall materials (glass, silicon nitride, corundum and silicon carbide)were evaluated. It was discovered that: (1)the effect of mode stirrer on heating characteristics depends on its material and the coefficient of temperature variation of Aluminum-Alumina mode stirrer is reduced by 44%;(2) under the action of mode stirrer, the corundum inner wall can improve the heating efficiency, but the glass inner wall has a poor effect on it;(3) changing the structure material of microwave reaction kettle has little effect on the heating efficiency and the combination of Polyethylene-Aluminum mode stirrer and silicon carbide inner wall can improve the heating uniformity.
