Abstract
A brief introduction to combustion synthesis ( SHS) is made, and a look back on the course of SHS development is also made briefly. The R&D of SHS go slow and arrives at a low tide gradually in recent decade after being at a high tide in the last two decades of the twentieth century. But, there are still some successful samples of the application, the combustion synthesis is indeed a new method to manufacture materials. Here, several useful and potentially useful technologies are introduced as following: 1 ) Centrifugal thirmit reaction. It has been widely used to manufacture the ceramic-lined steel pipes, but it is able to make other products such as the composite of ceramic and steel plate, and ferroalloys. 2) Powder production. Powders are the major products of SHS, the treatments after synthesis are also important for the quality of the powders. 3 ) Rective forging. This is an efficient one among the methods completing the synthesis and densification by one step. 4 ) Fabrication of nanopowders. Alkali metal salts are mixed with the reactants together, the salts melt and coat producing grains preventing them from growing and agglomerating. 5) Oxides by carbon combustion synthesis. The carbon is addid in reactants, the reaction takes place in flowing oxygen, carbon reacts with oxygen releasing heat to produce materials.关键词
