Kinetics of viscous flow sintering of glass–zircon composites. Effect of zircon volume fraction and particle size distribution

open access: yesOpen Ceramics, 2022
Viscous flow sintering of glass–zircon composites was studied by isothermal and constant-rate heating experiments. The sintering curves fitted very well to the developed kinetic model, based on the Kohlrausch–Williams–Watts (KWW) function. Increasing the

Development of a robust method for the determination of fluorine in liquid petroleum products

open access: yesResults in Chemistry, 2021
A robust method for the determination of total fluorine in liquid petroleum products is developed. The methodology is based on the oxidative pyrohydrolytic combustion of the sample, followed by the analysis of the evolved gases absorbed in an absorbing ...

Densification of irregular polydispersed glass particles described as a complex relaxation process

open access: yesOpen Ceramics, 2022
The sintering of compacts of irregular non-crystallising glass particles was studied by isothermal and constant-rate heating experiments in a hot stage microscope. The resulting data fitted very well to kinetic equations developed in this study, in which

Comportamiento de tejas de diferente color (rojo y paja) frente al biodeterioro

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio, 2014
Biocolonization of building materials is a critical problem for the durability of constructions. Industrial experience shows that straw coloured roofing tiles are more prone to colonization than red roofing tiles, even having similar characteristics. The
