Carbothermic Reduction by Microwave Heating
ISIJ International, 2001 The carbothermic reduction of iron ores is the most important reaction in ironmaking and has been performed mainly in the Blast Furnace. In the last years, several new processes have been proposed as alternatives, and many types of reactors have been tested. The most promising processes are those in which a mixture of iron ore and carbonaceous material

Preparation of Neptunium Mononitride by Carbothermic Reduction [PDF]
Journal of Nuclear Science and Technology, 1994 Neptunium mononitride with carbon and oxygen contents of less than 1,000 ppm was prepared by the carbothermic reduction of NpO2 in flowing N2 gas at 1,823 K, followed by the removal of excess carbon in a N2-H2 mixed gas stream at 1,723 K. It is suggested from the present result and also the consideration on the chemical form of residual carbon in ...
