Abstract: This paper mainly summarizes the methods to yield high density ultra-fine crystalline bulk sintering materials, including some advanced sintering methods, sintering process and inhibitors. The present situation and developing trend of various technologies are expounded. As a result, the author demonstrates that the sintering of ultra-fine composite powders can be further developed on the basis of detailed research on the ‘low-cost-high-efficiency’ sintering methods, equipments, and processes.

Key words: ultra-fine powder; composite powder; sintering technology
