The influence of firing conditions on the mineralogical composition of clay base ceramics is studied. Experimental samples fired in oxidation atmosphere at temperature rates 850, 900, 950, 1000 and 1050 with respect to high amount of CaO in raw materials (Ave. 18.76 %), these samples classified in Ca-rich clay group. The determination of chemical composition, phase structure and mineralogy were...

thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...

a major concern in the last few years has been the fact that the cultural centers are keeping distance with what they have been established for and instead of reproducing the hegemony, they have turned into a place for resistance and reproduction of resistance against hegemony. because the cultural centers, as urban public spaces in the last two decades, have been the subject of ideological dis...
