Spray Freeze Granulation of Submicron Alumina and its Sintering Behavior via Spark Plasma Sintering Wei Liu, Zhipeng Xie Abstract: Spray freeze granulation is an improved method based on spray granulation, solving many limitations of spray granulation. In this work, spray freeze granulation of submicron alumina is performed to explore the possibility of industrial-scale production of… Continue reading Spray Freeze Granulation of Submicron Alumina and its Sintering Behavior via Spark Plasma Sintering
