[ 1 ] - Effect of processing parameters on the mechano-chemical synthesis of nano crystalline Mo-Cu/Al2O3 composite
In this study, molybdenum-copper/alumina nano composite was synthesized with mechano-chemical method using high energy planetary ball milling. The molybdenum oxide, copper oxide and aluminum powder were used as starting materials and reaction appeared to occur through a rapid combustion reaction process. The evaluation of powder particles after different milling times was studied by X-ray diffr...
[ 2 ] - Mechano-chemical activation of MoO3-CuO/C powder mixture to synthesis nano crystalline Mo-Cu alloy
In this study, a high energy planetary ball milling technique was used to synthesize nano-crystalline Mo-Cu alloys. Molybdenum trioxide (MoO3) and copper oxide (CuO) were used as the starting materials. Carbo-thermal co-reduction of mixed Mo and Cu oxides powders was done with milling followed by a heat treatment at a high temperature. Differential thermal analysis/thermogravimetric (DTA/TG) wa...
[ 3 ] - Hydrogen evolution activity of NiMo-MoO2 produced by mechanical milling
In this study, mechanical alloying was done by a high-energy planetary ball milling technique. A mixture of NiO and MoO3 and graphite powders were used as initial materials. After milling of powder mixture with 40 wt.% additional graphite, a temperature of 400, 550 and 1000 °C for 1 h was considered for the heat treatment of powder mixture. Also, powder mixtures containing 60, 80 and 100 wt.% a...
