Microstructural characterization of sanitaryware, the relationship spinel and mullite
Simón Yobanny Reyes López,Juan Serrato Rodríguez,Satoshi Sugita Sueyoshi 한양대학교 세라믹연구소 2013 Journal of Ceramic Processing Research Vol.14 No.4
Sanitaryware reference industrial experimental compositions have been formulated, formed by slip casting and subsequently sintered in a laboratory electric furnace. Microstructural evolution was followed by HRTEM, BSE, X-ray diffraction and infrared spectroscopy. Thermal evolution of raw materials shows dehydroxylation of kaolinite, transformation to spinel and mullite, and transformation of α-quartz into β-quartz. Principal discussions are focused on the spinel and mullite evolution in the 900-1300 ο C temperature range. Evidence of the phase trans formation from spinelto mullite were found in single crystals characterized locally by fast Fourier transformand lattice fringe d spacing accounting for the coexistence of nanometric mullite with the cubic spinel phase. Back scattered electrons (BSE) in topographic mode have been used to show the presence of the spinel type intergrowth plates within the sanitaryware microstructure. Aspect ratio calculations and interplanar analysis of the distances shows less characteristic planes of spinel as mullitization and vitrification progresses, mullite planes increase up to 1250 ο C and decrease at 1300 ο C.
Determination of the activation energy for densification of porcelain stoneware
Simón Yobanny Reyes López,Juan Serrato Rodríguez,Satoshi Sugita Sueyoshi 한양대학교 세라믹연구소 2011 Journal of Ceramic Processing Research Vol.12 No.3
Experimental porcelain stoneware has been formed by slip casting and sintered by rate controlled dilatometry. Shrinkage has been measured at various constant heating rates up to 1300 oC by dilatometry. A kinetic field for stoneware firing has been set up by connecting points of equal density on the sintering rate curves to determine the activation energy for densification and to calculate optimum firing cycles. The activation energy for densification has been calculated from the slope of the isodensity curves. It has been observed that the activation energy increases with progressive sintering i.e. 470-497 kJ/mol for the intermediate sintering stage (1100-1225 oC) accounting for most of the densification. The abrupt shrinkage and low activation energy values during the intermediate sintering stage suggest a viscous flow mechanism of densification. The final sintering stage responsible for a reduced densification rate showed a lower 313 kJ/mol activation energy.

<P>We present multi-band results for GRB071010B based on Swift, Suzaku, and ground-based optical observations. This burst is an ideal target to evaluate the robustness of the E-peak(src) - E-iso and E-peak(src) - E-gamma relations, whose studies have been in stagnation due to the lack of the combined estimation of E-peak(src) and long-term optical monitoring. The joint prompt spectral fitting using Swift/Burst Alert Telescope and Suzaku/Wide-band All-sky Monitor data yielded the spectral peak energy as E-peak(src) of 86.5(-6.3)(+6.4) keV and E-iso of 2.25(-0.16)(+0.19) x 10(52) erg with z = 0.947. The optical afterglow light curve is well fitted by a simple power law with temporal index alpha = -0.60 +/- 0.02. The lower limit of temporal break in the optical light curve is 9.8 days. Our multi-wavelength analysis reveals that GRB071010B follows E-peak(src) - E-iso but violates the E-peak(src) - E-gamma and E-iso - E-peak(src) - t(jet)(src) at more than the 3 sigma level.</P>
