In this study, transparent alumina is produced using three types of experiments that are compared and analyzed to check sample properties and energy savings. The output power significantly decreases from 46% to 22% when a typical energy efficient configuration using a BN 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, consumption is 17% lower in the energy efficient configuration compared to the traditional configuration. Therefore, this method has potential for fabricating transparent ceramic of various materials with uniform transparency.
