...) is a fusion welding process in which two metals become bonded after being heated by superheated metal that has experienced an aluminothermic reaction. This article describes the thermite welding principles by presenting equations of the aluminothermic reaction that occurs in thermite welding. It provides...

... includes a wide variety of so-called aluminothermic reactions and, more recently, a variety of similar highly exothermic chemical reactions known as combustion synthesis reactions. What these have in common is that they all employ a highly exothermic chemical reaction between mixtures of finely divided...

... by sintering and/or melting. The process for niobium differs only in that the metal is most commonly reduced by aluminothermic reduction of oxide. In this process, oxide impurities slag from the molten niobium. For tantalum and niobium, electron beam (EB) melting is widely used for further purification...

... to more acceptable levels, particularly for austenitic stainless steels, it also was at the expense of increased oxidation. With higher sintering temperature (>1205 °C, or 2200 °F), the reaction between residual oxygen and carbon is more complete, and delubing is, therefore, preferably completed...
