| Abstract Scope |
In this study, transparent alumina is produced by spark plasma sintering (SPS) using three types of experiments that are compared and analyzed to check sample properties and energy savings. The output power during SPS significantly decreases when a typical energy efficient configuration using a boron nitride coated graphite foils is used, but most samples have cracks. The presented new method results in the prevention of cracks, full densification, and uniform transparency in alumina. Furthermore, energy consumption is significantly lower in the energy efficient SPS configuration compared to the traditional SPS configuration. The developed method has potential for fabricating transparent ceramic of various materials with uniform transparency. |
