Characterisation of Geological Samples with Dual‐Energy XCT: A Comparison of Three Different Scanners

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points A stoichiometric calibration method for dual‐energy computed tomography allows non‐destructive characterisation of materials. Different acquisition settings and three different scanners were tested, characterising three rocks of known composition. Comparison of measurement results reveals the key parameters to be considered to perform useful

Effect of nanosilica and nanoboehmite in the pyroplastic deformation of a porcelain tile paste

open access: yesInternational Journal of Applied Ceramic Technology, EarlyView.
Abstract Porcelain tiles are low‐porosity ceramic coatings, formed by a mixture of clay minerals, quartz, and feldspars, and fired at temperatures close to 1200°C with formation of a liquid phase that can result in unwanted pyroplastic deformations. In addition, the rectangular formats, large dimensions, reduced thicknesses, and fast thermal cycles ...

Slip casting porous silicon nitride for high‐temperature radar frequency radomes

open access: yesInternational Journal of Applied Ceramic Technology, EarlyView.
Abstract Silicon nitride (Si3N4) is a promising candidate for ceramic radar frequency (RF) radomes. In this study, suspensions have been developed to slip cast Si3N4 for RF windows utilizing 6 wt.% yttrium oxide (Y2O3)‐2 wt.% aluminum oxide (Al2O3) and 5–15 wt.% ytterbium oxide sintering aids.

Femtosecond laser crystallization of YAG in yttrium aluminosilicate glasses

open access: yesInternational Journal of Applied Glass Science, EarlyView.
Abstract This work demonstrates the capability to crystallize YAG via femtosecond pulsed laser. Challenges in using melt‐quench glass are shown to restrict glass composition and have not yielded YAG via femtosecond laser crystallization. An alternative glass‐making technique was used to fabricate a range of compositions not otherwise possible.
