[ 2 ] - The optimization of dispersant content in alumina castable containing nano-titania
In this research, two series of ultra-low cement high alumina refractory castables containing 0 and 0.4 wt.% of nano-titania were prepared using different amounts of polycarbonic acid (DOLAPIX FF 26) as a dispersant. Several characteristics including microstructure, flowability, mechanical strength, bulk density and apparent porosity of the samples were analyzed. The results showed that the opt...
[ 3 ] - Hydrothermal synthesis of monoclinic - cubic Li2TiO3 hybrid nanocomposite microspheres
Li2TiO3 compound is one of the most important tritium breeding ceramics for industrial application in the nuclear fusion reactor. The use of the hydrothermal method for preparing ceramic composite materials is new trend. In this work, hybrid nanocomposite microspheres of the nanocrystallites Li2TiO3 were prepared at low temperature 400°C. Nanocomposite powders synthesized by the batch supercrit...
[ 4 ] - Ultrasonic-assisted solvothermal synthesis of self-assembled Copper Ferrite nanoparticles
The aim of this work was to characterize copper ferrite nanoparticles synthesized via solvothermal method and to investigate the effects of ultrasonic waves on the synthesis efficiency. Crystal structure, functional groups, microstructure, particle size, magnetic properties, specific surface area, porosity distribution and photocatalytic activity of the synthesized nanoparticles were also inves...
