EFFECT OF THE HEAT OF REACTION DURING THE ALUMINOTHERMIC PROCESS OF ILMENITE Y.Z.Lan1,R.W.Smith2,J.Liu1 (1.Materials Department, Yunnan University, Kunming 650091, China;2.Metallurgical and Materials Department, Nevada University of Reno, NV89503,Nevada, USA) Abstract:The influence of the heat of reaction during the aluminothermic process for the production of ferrotitanium was investigated......
Pozzolanic Reaction Kinetics of Coal Ashes郑洪伟,钱觉时摘 要:The pozzolanic reactivity was determined by the hydration kinetics of pozzolanic reaction based on the fact that the hydration products of active SiO2 and Al2O3 with lime were soluble in dilute hydrochloric acid. The results show that the pozzolanic reaction of active SiO2 and Al2O3 of coal ashes......
evolution reaction (HER) in oxalic acid solution under simulated sunlight irradiation. The highest photocatalytic activity of the as-obtained CuO was achieved at the calcination temperature of 1 000... photocatalytic reaction mechanism on the CuO photocatalyst for HER in oxalic acid solution was also discussed. Key words: copper oxide (CuO); hydrogen evolution reaction (HER); photocatalytic activity; oxalic......

Reaction between Lanthanum and Phosphorus in Steel DONG Lu-ren1,ZHU Li-xin2,SHA Ai-xue1,WANG Fu-ming1,CHEN Ya-xian2,LI Shang-yi3,WU Cheng-jian1 (1.Metallurgical Engineering School, University...:Using Miedema binary heat formation model, it was confirmed thermodynamically that the fixation of P by La is possible. The reaction between La and P was studied by means of SEM and TEM. The result......
with Ti3SiC2 above 1 273 K and new phases like TiCx, Ti5Si3 and TiSi2 are identified. The reactions are closely related to temperature and content of Ti3SiC2 in Ti. During the reaction process, Ti3SiC2... the Ti3SiC2 and reacts with titanium furthermore. The diffusing of silicon is believed to be the determinant ingredient of the reaction. Key words: Ti3SiC2; Ti; high-temperature reaction 1 Introduction......
