Control of particle microstructure and its assembly structure is a key issue for achieving high quality advanced materials and give them high functions. In this paper, manufacturing process of advanced ceramics using raw powder materials is introduced to make clear the role of powder structure control for high quality materials. Besides, individual particle structure control is also important to develop functional particles and advanced materials by controlling particle assembly structure. In this paper, processing technology of composite particles is also discussed to explain the roles for developing advanced materials.
