Non-isothermal sintering of powdered vitrified composites. A kinetic model
(Elsevier, 2019)
This report sets out the results obtained on studying the sintering process of glass–zircon composites,
analysing the microstructural changes that developed on modifying zircon content. The sintering of composites with ...
Green strength testing of pressed compacts: An analysis of the different methods
(Elsevier, 2008)
This paper presents a comparative study of three- and four-point bending tests and diametral compression (DC) tests, used to measure the mechanical strength of green pressed compacts. The study has been conducted on pressed ...
Calcium carbonate decomposition in white-body tiles during firing in the presence of carbon dioxide
(Elsevier, 2013-08)
This study examines the thermal decomposition process of the calcium carbonate (calcite powder) contained in test pieces of porous ceramics, of the same composition as that used in manufacturing ceramic wall tile bodies, ...
Porous single-fired wall tile bodies: Influence of quartz particle size on tile properties
(Elsevier, 2010)
This study examines the effect of quartz particle size in raw material composition customarily used for the manufacture of porous single-fired wall tile bodies on the characteristics of the green tiles and on the thermal ...
Calcium carbonate thermal decomposition in white-body wall tile during firing. I. Kinetic study
(Elsevier, 2010)
This study examines the thermal decomposition of calcium carbonate, contained in disk-shaped test pieces formed from a mixture of raw materials of a similar composition and characteristics to those of the mixtures customarily ...
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 ...
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 ...
Sinter-crystallisation kinetics of a SiO2–Al2O3–CaO–MgO–SrO glass-ceramic glaze
(Elsevier, 2020-03-15)
This paper examines the microstructural development and kinetics of the sintering and crystallisation processes of a SiO2–Al2O3–RO (R = Ca, Mg, Sr) glass-ceramic glaze. Crystallisation and sintering kinetics were studied ...
Kinetic study of calcite particle (powder) thermal decomposition: Part I
(Elsevier, 2008)
In the first step of the firing cycle used to manufacture white-firing wall tile bodies, the calcium carbonate that is added, as a source of CaO, to the clay raw materials mixture used to form these bodies needs to decompose. ...
Fracture properties of spray-dried powder compacts: Effect of granule size
(Elsevier, 2008)
Inappropriate mechanical properties of spray-dried powder compacts lead to significant green product losses, entailing considerable costs in ceramic tile manufacture as well as serious environmental problems. In addition, ...
