High Temperature Materials... treatment [16,17] is an effective way to remove boron from MG-Si, but with the disadvantage of high temperature, essential hydrogen water vapour, small contact area, and closed system. However......
Low-Cost Preparation of Boron Nitride Ceramic Powders李端State Key Laboratory of Advanced Ceramic Fibers & Composites, College of Aerospace & Materials Engineering, National University of Defense Technology摘 要:The amorphous boron nitride ceramic powders were prepared at 750-950 ℃ by the low-cost urea route, and the effects of preparation temperatures......
October 2011 Abstract: V-Ti-Fe master alloys were prepared by metallothermic reduction method, and the influences of the mass ratio of V2O5 to TiO2, Al and Al-Mg alloy addition amounts on the metal recovery..., but the recovery rate of Ti does not increase any more. The possible reason is that the Al-Mg alloy is wasted seriously in the smelting process for its high activity. In addition, considering the factor......
