Preliminary Research on the Thermal Field in Concrete for Microwave Heating Application

Abstract:

Magnesium along with its alloy has garnered significant attention for potential utilization in biomedical applications, owing to its biodegradable and biocompatible characteristics. This paper aims to present preliminary research on the microwave heating of a concrete crucible designed to ensure the proper temperature for the sintering of magnesium alloy. Due to the reflection coefficient of microwaves by the magnesium alloy, the utilization of a microwave susceptor becomes imperative for effective heating. The research primarily focuses on modeling the temperature distribution within the concrete crucible to ensure a consistent level of heat for the sintering process of the magnesium alloy. As a result of the modeling process, temperatures up to 298°C have been achieved across a broad range of microwave power inputs (600-1200 W).
