Delayed curvature and residual stresses in porcelain tiles
Elsevier (2013)Most industrial porcelain tiles suffer changes in their curvature after firing: such process is known as delayed curvature. One of the hypotheses used to explain this phenomenon is based on the relaxation of residual ... -
Delayed curvatures in porcelain tiles : analysis and measurement of incluencing factors
Göller Verlag GmbH (2008)Göller Verlag GmbH Glazed and unglazed porcelain tiles exhibit a phenomenon known as 'delayed curvatures', which consist of the change in tile curvature after the tiles leave the kiln. This phenomenon becomes more problematic ... -
Densification of irregular polydispersed glass particles described as a complex relaxation process
Elsevier (2022)The sintering of compacts of irregular non-crystallising glass particles was studied by isothermal and constantrate heating experiments in a hot stage microscope. The resulting data fitted very well to kinetic equations developed ... -
Densification of monomodal quartz particle beds by tapping
Elsevier (2008)A study has been undertaken to determine how the mean particle size of monomodal quartz particle beds and the bed preparation method affect initial and final bed apparent density and the kinetics of densification by tapping. ... -
Deposition of Al2O3-TiO2 Nanostructured Powders by Atmospheric Plasma Spraying
Springer Verlag (2008)Al2O3-13%TiO2 coatings were deposited on stainless steel substrates from conventional and nanostructured powders using atmospheric plasma spraying (APS). A complete characterization of the feedstock confirmed its ... -
