Mgo-C refractories due to suitable properties which mainly related to presence of graphite and Carbon bonding are widely used in steel industry. The most disadvantages of these type of refractories is lack of bonding at high temperature. In the present work tried to investigate nitride bonding formation and effect on physical, mechanical properties, phase analysis and microstructure of samples. Result showed that because of presence of forsterite and silicon nitride together thermomechanical properties could be improved.

ZnO-CdO nanocomposite was synthesized by a W/O microemulsion method. Effect of calcination temperature on phase transformations, crystal size and specific surface area of ZnO-CdO nanocomposite were investigated. The synthesized Products were studied by the X-ray diffraction results (XRD), thermogravimetric and differential thermal analysis (DTA-TG), Brunauer–Emmett–Teller surface area measurement (BET), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Effect of pH on the removal of methyl blue and acid methyl orange was studied. XRD results showed that ZnO-CdO nanocomposites with crystallite size in nanometer scale were formed. Zinc oxide-cadmium oxide particles synthesized at 400 ˚C had the highest adsorption properties. The results showed that the adsorption of methyl blue and methyl orange on the surface of ZnO-CdO nanoparticles was higher at acidic conditions.
