Effect of the doping method on the sintering characteristics of Gadolinium-doped Ceria
Description :
Ce0.8Gd0.2O2-d (GDC) is considered one of the most promising electrolyte for intermediate temperature solid oxide fuel cell (IT-SOFC). The reduction of the sintering temperature is one of the most important challenge for the production of fully dense electrolyte. The sintering behaviour of a ceramic...

Densification behaviour of screen printed Gadolinia doped Ceria films: effect of CuO
Description :
The effect of CuO on the densification of a Gadolinia doped Ceria (Ce0.8Gd0.2O2-d, GDC) deposited by screen printing on a GDC/NiO anode produced by tape casting was considered aiming to a complete co-firing of the anode-electrolyte half cell. A comparative study on a CuO-doped and undoped GDC reveal...

Microstructure characterization of boride-based ultra-high-temperature ceramics
Description :
Hafnium and zirconium borides are leading candidate materials for use in ultra-high-temperature applications thanks to their excellent combination of physical, mechanical and oxidation resistance properties. It has been shown that the addition of MoSi2 allows the densification without the applicatio...

TEM characterization of carbide-based ultra-high temperature ceramics
Description :
Owing to their attractive properties such as high melting point, high thermal and electrical conductivity, high stiffness and hardness, the carbides of the IV group of transition metals are potential candidate materials for ultra-high temperature applications. Despite their good properties in aggres...

Colour performance of ceramic nano-pigments
Description :
Ceramic nano-pigments have been recently developed for ink-jet printing decoration of ceramic tiles by the quadrichromy technology (cyan, magenta, yellow, and black colours). The colouring mechanisms and performance of these nano-pigments (CoAl2O4, Au, (Ti,Cr,Sb)O2, CoFe2O4) were investigated by DRS...

Recycling PC-TV waste glass in clay bricks and roof tiles
Description :
Disposal of PC and TV sets is a growing problem, involving for over 40 wt. % waste glasses with high Pb (funnel) or Ba-Sr concentration (panel) which cannot be recycled in the glass manufacture. A possible way to re-use these glasses is in the manufacturing of clay bricks and roof tiles, that was ap...

Predicting the initial rate of water absorption in clay bricks
Description :
The effect of product characteristics and processing conditions on the initial rate of water absorption of fifteen clay bricks was investigated and the influence of porosimetric parameters (amount, size and tortuosity of pores) as well as of phase composition (amount of calcium-silicates and amorpho...

Process of pyroplastic shaping for special-purpose porcelain stoneware tiles
Description :
A novel technique to manufacture special-purpose tiles (i.e. trim pieces, steps, skirting boards, etc.) has been recently developed on the basis of a pyroplastic shaping of porcelain stoneware tiles. This innovative process involves a second firing, peaking at temperatures close to those of sinterin...

Synthesis of Cr-doped CaTiSiO5 pigments by spray drying
Description :
Cr-doped CaTiSiO5 were synthesized by spray drying of an aqueous solution of precursor salts plus further calcining the resulting powders. The samples were prepared by conventional ceramic method as well for comparison study as ceramic pigments. The evolution of the present crystalline phases with a...

Microwave-assisted synthesis of Pr-ZrSiO4, V-ZrSiO4 and Cr-YAlO3 ceramic pigments
Description :
An innovative two-steps route was successfuly applied to the microwave-assisted synthesis of Pr-ZrSiO4, V-ZrSiO4 and Cr-YAlO3 ceramic pigments. It is able to reduce the total synthesis time from many hours down to a few minutes. Industrial batches were pelletized and underwent a short time pre-heati...
