为了节省时间和能量，优选由稳定的12相交流（AC）电弧等离子体产生的大体积放电来熔化粒状玻璃材料。电极结构可以控制等离子体系统的放电行为和高温区。在这项研究中，电弧放电的空间特性进行了检查，通过图像分析与高速摄像机。利用显微镜和X射线衍射仪研究了无碱玻璃颗粒的熔化特性。这是首次研究等离子体的空间特性与玻璃颗粒性质之间的关系。结果表明，电弧存在面积与电极结构密切相关。采用多相交流电弧进行空中熔化时，空中粉末的分布和电弧的空间特性是重要的影响因素。这项研究提供了有效的粒子处理根据电极配置的信息。
A large volume discharge produced by a stable 12-phase alternating current (AC) arc plasma is preferable to melt the granulated glass materials for time and energy saving. The discharge behavior and the high-temperature region of the plasma system can be controlled by the electrode configurations. In this study, the spatial characteristics of the arc discharge were examined by image analysis with a high-speed camera. The melting characteristics of alkali-free glass particles were investigated by microscope and X-ray diffractometry. This is the first time to investigate the relationship between spatial characteristics of plasma and glass particle property. Results show the arc existence area is strongly related to the electrode configuration. Distributions of in-flight powders and the spatial characteristics of arc are important factors when using multiphase AC arc for in-flight melting. This study provides information of efficient particle treatment according to the electrode configuration.
