Effect of kaolin addition on the sinter-crystallisation kinetics of compacts of a crystallising frit
(Elsevier, 2022-08-22)
Non-isothermal techniques were used to study the sintering and crystallisation kinetics of an anorthoclase- and diopside-devitrifying frit and mixtures of this frit with a commercial kaolin. Raising kaolin content was ...
Hardness and Young's modulus distributions in atmospheric plasmas prayed WC–Co coatings using nanoindentation
(Elsevier, 2011-05-25)
A statistical indentation analysis of WC–Co coatings obtained by atmospheric plasma spray (APS) with two secondary plasma gases, H2 and He, was investigated using an instrumented indentation technique with the aim of ...
Influence of composition on mechanical behaviour of porcelain tile. Part III: Effect of the cooling rate of the firing cycle
(Elsevier, 2011)
This paper is the third part of a study focusing on determining the influence of the porcelain tile composition on mechanical behaviour of sintered bodies. Tile compositions were prepared according to a simplex-centroid ...
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 ...
Use of coatings to minimise acid emissions during ceramic tile firing.
(© 2011 Elsevier, 2011-06)
The manufacture of traditional ceramic products (ceramic tiles, roof tiles, and bricks) is often associated with the emission of F, Cl, and S compounds during the firing stage. According to the literature, fluorine emissions ...
Effect of slurry properties and operational conditions on the structure and properties of porcelain tile granules dried in an acoustic levitator
(Elsevier, 2012)
Spray-drying is a unit operation highly important in many industrial applications. In this work, the influence of the drying conditions on the final grain properties has been investigated in single droplet experiments.Porcelain ...
Relation between the scratch resistance and the chemical structure of organic-inorganic hybrid coatings
(Elsevier, 2011)
Organic–inorganic hybrid materials can be defined as materials combining organic and inorganic domains in a nanometric scale. The development of these organic–inorganic hybrids has achieved properties from both organic and ...
ZnO and CuO crystal precipitation in sintering Cu-doped Ni–Zn ferrites. I. Influence of dry relative density and cooling rate
(Elsevier, 2011-10-15)
This paper presents a study of the precipitation of ZnO and CuO crystals during the sintering of Cu-doped Ni–Zn ferrites. The nature of the Zn- and Cu-containing crystal precipitates was determined by scanning electron ...
Fracture patterns of quartz particles in glass feldspar matrix
(Elsevier, 2012)
We report a comparison between experimental evidences and simulation results of the micro cracking in ceramic materials provoked by the cooling process. The solid model and the fracture process are carried out using the ...
