Self-Propagating Method and its Role in Environmental Protection

The self-propagating high-temperature synthesis (SHS) method have been developed Through The world-wide in order to production of beneficial engineering and other functional materials, such as advanced ceramics, intermetallics, catalysts and magnetic materials. This method uses self-sustaining solid-flame combustion reactions which develops very high internal material temperatures during very short periods. Therefore, has many advantages over traditional methods, such as much lower energy costs, lower environmental impacts, ease of manufacturing and capability for producing materials with unique properties and characteristics. This paper introduces the SHS method and its advantages and discusses a numerous applications with environmental Trends, such as highly active catalysts for exhaust emission control and methane conversion and various methods of neutralization or recycling industrial inorganic wastes. Since SHS can be initiated and completed at Environmental standard conditions, it can also be utilised successfully for dealing with toxic or radioactive materials and contaminated areas by creating large-scale protective coatings or vitrification, consolidation and encapsulation of dangerous wastes.
