Sintering refers to a process that is utilized to form a dense solid typically assisted by thermal energy and/or pressure.1-4 It is a major manufacturing approach that has been widely applied to a diverse range of materials.5-10 Even though sintering has been extensively studied in the modern era of ceramic science for over five decades, and numerous new technologies have been developed,11-15 in the case of conventional thermal sintering of ceramic materials, they are still accomplished at high temperatures, as a rule of thumb, ~ 50%-75% of their melting points.1
