Silicon carbide nanowires have been synthesized at 1400 degrees C by carbothermic reduction of silica with bamboo carbon under normal atmosphere pressure without metallic catalyst. X-ray diffraction, scanning electron microscopy, energy-dispersive spectroscopy, transmission electron microscopy and Fourier transformed infrared spectroscopy were used to characterize the silicon carbide nanowires....

In the present study, reduction of zinc oxide from the pellets made of steelmaking electric arc furnace dust has been investigated. Effects of such parameters as the type of carbon material (graphite, coke and charcoal) as well as time and temperature on the reduction reaction have been examined. The reduced (dimensionless) time method was applied to perform a kinetic analysis of the system. Ex...

Iron oxide scale generally forms on low-carbon steel surfaces during the hot rolling processes andproduces as solid waste more than 100 thousand tons per year. The utilization of iron scaleis one possible way to reduce production cost for plants and promote environmental protection. Acrylonitrile-Butadiene-Styrol-Copolymer (ABS) is widely used engineering plastic automotive parts because its hi...

The carbothermic co-reduction of nickel laterite ore and red mud realized the simultaneous reduction nickel, iron in ore, at high efficiency. Nickel were recovered form ferronickel. size characteristics ferronickel particles grindability products are essential for obtaining good technical indicators. influence conditions on particle relative was investigated by a test, analysis, determination. ...
