Surface Contamination of Alumina Ceramics by Carbon
Article history: Received: 01.05.2016. Received in revised form: 25.07.2016. Accepted: 06.09.2016. This study presents the results of investigating the cause of contamination of aluminum oxide ceramics (Al2O3) in the form of brown colored stain. Contaminated ceramic surfaces were examined with the scanning electron microscope (SEM) equipped with the Energy Dispersive Spectrometer (EDS). The res...
متن کاملDetection of tetragonal zirconia in alumina–zirconia powders by thermoluminescence
The thermoluminescence (TL) after excitation by UV or X-rays radiation of alumina-zirconia powders is investigated. The composites present five of the characteristic peaks of zirconia at −170, −145, −90, 0 and 95 °C. After a thermal treatment of mixed oxides, a new peak is observed at −35 °C in TL. This peak reveals the presence of stabilized tetragonal zirconia in the material. Moreover by com...
متن کاملIn vitro experimental study of bonding between aluminium oxide ceramics and resin cements.
UNLABELLED To evaluate bond strengths of different resin cements to two aluminum oxide-based ceramics. METHODS One hundred ten ceramic cylinders were produced and given four different surface treatments. Resin cement cylinders were then bonded to the ceramic cylinders using different resin cements and the bond strength was determined by shear testing to the breaking point. We were thus able t...
متن کاملSynthesis and thermoluminescence properties investigation of nano-structured alumina for high dose measurement
In this study, nanostructured alumina was synthesized by solution combustion method and its thermoluminescence properties was investigated. X-raydiffraction (XRD) and scanning electron microscopy (SEM) were conducted to investigate the crystal structure, morphology and the particle size of the powders. It was observed that nano structured α-Al2O3 particles with nano flake morphology and thickne...
متن کاملINFLUENCE OF NANO SILICA ON PROPERTIES AND MICROSTRUCTURE OF HIGH ALUMINA ULTRA-LOW CEMENT REFRACTORY CASTABLES
Colloidal silica bonded refractory castables have been developed recently. It was found that colloidal silica is one of the best binders can substitute other binders such as cement in No Cement Castable (NCC) and Ultra Low Cement Castable (ULCC) refractories. Also composition of colloidal silica with appropriate additives resulted in a gel form which makes the initial strength. Moreover, the na...
