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. ...
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, ...
Kinetic study of the thermal decomposition process of calcite particles in air and CO2 atmosphere
(Elsevier, 2013-05)
The thermal decomposition process of calcite particles (0.45–3.60 mm average diameter), made up of porous agglomerates of very small CaCO3 microcrystals, was studied in the 975–1216 K temperature range. The experiments ...

Calcium carbonate thermal decomposition in white-body wall tile during firing. II. Influence of body thickness and calcite content
(Elsevier, 2012-05)
The thermal decomposition process of the calcium carbonate (calcite powder) contained in porous ceramic pieces, with the same composition as that used industrially to manufacture white-firing wall tile bodies, was studied ...
Study of the rheological behaviour of monomodal quartz particle beds under stress: a model for the shear yield functions of powders
(Elsevier, 2011-09-15)
A model is proposed that describes the yield locus of powders. The model is based on the adhesive contact of elastic spheres theory developed by Johnson, Kendall, and Roberts (JKR model). The proposed model improves the ...
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 ...
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, ...
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 ...
Non-destructive measurement of bulk density distribution in large-sized ceramic tiles
(Elsevier, 2010)
An apparatus has been designed, built, and patented that is able, non-destructively, to determine bulk density distribution in large-sized ceramic tiles. The proposed method, based on the X-ray absorption technique, provides ...
