...Marino Maggetti; Antoine D’Albis Abstract: Optical microscopy, X-ray diffraction, X-ray fluorescence and scanning electron microscopy analyses were carried out on a typical Sèvres soft (frit) porcelain plate from 1781 in order to determine the chemical and mineralogical composition as well...

...Wen Bai; Wang Zhu; Mohamed A. Moustafa; Junwu Dai Porcelain cylindrical electrical equipment (PCEEs), such as potential and current transformers, are critical components of electrical substations and essential to power supply networks. Nevertheless, previous strong earthquakes have rendered high...

... industry and especially for the production of porcelain stoneware tiles. To achieve the proposed objectives, a geological study was carried out through the mapping and identification of the present lithologies, lithogeochemical characterization using X-ray diffraction, inductively coupled plasma optical...

... and Denkaka areas, respectively. The objective of this study was to examine these materials for the purpose of using them to produce quality electrical porcelain insulators. The clay samples were characterized for their chemical composition, mineralogy, thermal properties, plasticity, and particle-size...

...J. Victor Owen Abstract Double corona structures separating relict glass frit from metakaolinite in a teapot lid excavated from the Bow porcelain factory site in Stratford, east London record a history of partial melting and subsequent subsolidus reaction between the quenched melt phase...

... matrix; (2) A soft-paste (artificial) porcelain body (10 % W. A.), containing quartz +calcic plagioclase (An 88–95 ) + glassy matrix. The latter is inferred to derive from a former frit. A coronitic, amorphous (as revealed by electron backscattered diffraction analysis) reaction rim is visible around...

...Andrew S. Whittaker, M.EERI; Gregory L. Fenves, M.EERI; Amir S. J. Gilani The earthquake performance of 196-kV, 230-kV, and 550-kV porcelain transformer bushings was studied by earthquake-simulator experimentation and analysis. The fundamental frequencies of the 196-kV, 230-kV, and 550-kV bushings...

... was unable to sustain the High Level qualification shaking without oil leakage and slip of the porcelain units. Two retrofit details utilizing two semicircular ring plates and epoxy filler were prepared by utility representatives with the objective of limiting slip of the UPPER-1 porcelain unit over...

... form the basis of many modern materials, but the first sophisticated human use was in porcelains from Jingdezhen, China. From the initial discovery of kaolin and its sculptural use 2000 years ago to today's modern applications in nanocomposites, kaolin has been important throughout cultural history...

...Angel Sanz; Joaquín Bastida; Angel Caballero; Marek Kojdecki ABSTRACT Compositional and microstructural analysis of mullites in porcelain whitewares obtained by the firing of two blends of identical triaxial composition using a kaolin B consisting of ‘higher-crystallinity’ kaolinite or a finer...

...Emre Gönülcü, M.EERI; Tansu Gökçe, M.EERI; Ercan Yüksel; Engin Orakdöğen One of the most effective methods of improving high-voltage (HV) porcelain insulator earthquake performance is seismic isolation. A low-cost seismic isolation device consisting of polyurethane springs has been developed...
