Hydrated aluminium sulfate precipitation by enzyme-catalysed urea decomposition
Kara, Ferhat; Şahin, G (Elsevier Sci LTD, 2000)Hydrated basic aluminium hydroxide precipitates were obtained from aluminium sulphate solution at room temperature and at 92 degrees C by using urea. Enzyme urease was used to decompose urea at room temperature. It was ... -
Improvement of sintering and microstructural homogeneity of a diphasic mullite
Kara, Ferhat; Şener, O (Elsevier Sci LTD, 2001)Effect of seeding of boehmite-colloidal silica mixture with aluminium sulphate-colloidal silica mixture on its mullite formation and sintering behaviours and microstructural development was studied. It was observed that ... -
Microstructural characterization of reactively sintered mullites
Kara, Ferhat; Turan, Servet; Little, JA; Knowles, KM (Amer Ceramic Soc, 2000)Mullite ceramics have been produced by reaction sintering of powders prepared using pseudoboehmite-colloidal silica and aluminum sulfate-colloidal silica mixtures. The microstructural development of these mullites was ... -
Microstructural characterization of surface layers formed on a low alloy steel during erosion - oxidation in a fluidized bed
Rogers, PM; Hutchings, IM; Little, JA; Kara, Ferhat (Chapman Hall LTD, 1997)Low alloy steel specimens were subjected to erosion-oxidation in a simulated fluidized bed environ ment in the range 100-600 degrees C. Transmission electron microscopy was carried out on the surfaces which experienced ... -
Seramik sanayii hızlı pişirim fırınlarda kullanılan rulo malzemesi müllitin üretimi ve mekanik özelliklerinin belirlenmesi
Bu çalışmada, $\alpha-Al_2O_3$ ve kaolin kullanılarak, müllit $(3Al_2O_3. 2SİO_2)$ matriks elde edilmiş ve bu malzemenin seramik hızlı pişirim fırınlarının bir yapı elemanı olan döner rulo malzemesi yerine kullanılabilme ... -
Seramik sanayii hızlı pişirim fırınlarda kullanılanan rulo malzemesi müllitin üretimi ve mekanik özelliklerinin belirlenmesi
Yorulmaz, S.; Erkmen, Engin Ziya; Kara, Ferhat (Scientific and Technical Research Council of Turkey, Ankara, Turkey, 1999)A mullite matrix ceramic was developed for use as the roller material in fast fire kilns. Samples of the mullite ceramic were produced from mixtures of domestic ?-Al2O3 and kaolin clay through conventional methods of ceramic ...
