Non-isothermal sinter-crystallisation of satin glazes: A kinetic model
(Elsevier, 2018-05)
Many materials of a glass-ceramic nature are obtained by glass particle sinter-crystallisation, whose process kinetics have been studied very little. The present study analyses the physico-chemical transformations that ...
Molten salt attack on multilayer and functionally-graded YSZ coatings
(Elsevier, 2018-08-01)
Thermal barrier coatings have been extensively studied in the last years in order to increase the operational temperature of the current gas turbines as well as to improve the coating lifetime. Many coating characteristics ...
Effect of fluorine and nitrogen content on the properties of Ca-Mg-Si-Al-O-(N)-(F) glasses
(Elsevier, 2017)
X-ray amorphous glasses of composition (in equivalent percent) 15Ca:15Mg: 55Si:15Al:(100-x-y)O:xN:yF with x=0, 10, 15 and y=0, 1, 3, 5, were prepared by melting and casting. The effects of oxygen substitution by fluorine ...

This ...
45S5 bioactive glass coatings by atmospheric plasma spraying obtained from feedstocks prepared by different routes
(Springer Verlag, 2014-12)
45S5 bioactive glass powders with the composition of 45 SiO2, 6 P2O5, 24.5 CaO and 24.5 wt% Na2O were melted and quenched in water to obtain a frit. The frit was milled using two different routes: dry milling followed by ...
Large scale synthesis of nanostructured zirconia-based compounds from freeze-dried precursors
(Elsevier, 2013)
Nanocrystalline zirconia powders have been obtained at the multigram scale by thermal decomposition of precursors resulting from the freeze-drying of aqueous acetic solutions. This technique has equally made possible to ...
