Asbestos-containing waste has been continuously generated due to the disposal of asbestos-containing products, and the development of asbestos detoxification and recycling technologies are required due to a lack of landfills. In this study, asbestos-containing waste was detoxified by a microwave heat treatment that used silicon carbide balls, which are inorganic heating elements that absorb microwaves and release heat at room temperature. For efficient heat treatment, the asbestos-containing waste was powdered by crushing and grinding processes and then a detoxification heat treatment was performed. The asbestos-containing waste powder particle size, heat treatment temperature, and heat treatment duration were adjusted to investigate the effect of the heat treatment conditions on the detoxification characteristics. After the heat treatment, the detoxification characteristics of asbestos-containing waste were analyzed using X-ray diffraction and scanning electron microscopy. Asbestos was completely removed from the crystal structure and microstructure when the microwave heat treatment was performed at 1200 °C for over 60 min and at 1300 °C for over 30 min. Using silicon carbide balls in the heat treatment enabled fast heat treatments because heating to the target temperature was possible within a short period of time.

由于对含石棉产品的处理，含石棉废物不断产生，由于缺乏垃圾填埋场，需要开发石棉解毒和循环利用技术。在这项研究中，通过使用碳化硅球的微波热处理对含石棉的废物进行了解毒，碳化硅球是吸收微波并在室温下释放热量的无机加热元件。为了进行有效的热处理，将含石棉的废物通过粉碎和研磨工艺进行粉化，然后进行解毒热处理。调整含石棉废粉的粒径，热处理温度和热处理持续时间，以研究热处理条​​件对排毒特性的影响。热处理后 利用X射线衍射和扫描电子显微镜对含石棉废物的排毒特性进行了分析。当在1200°C进行60分钟以上和1300°C进行30分钟以上的微波热处理时，石棉已从晶体结构和微结构中完全去除。在热处理中使用碳化硅球可以实现快速热处理，因为可以在短时间内加热到目标温度。
