Preparation of chamott es as raw material for low - cost ceramic membranes
(Wiley, 2016)
Low cost ceramic membranes are usually prepared fro
m a mixture of natural raw
materials and some organic porogen agent, as starch
. The fact that the porogen must be
completely eliminated during firing, leaving an ...

Eficiência energética na fabricação de placas cerãmicas mediante a utilização de óleo térmico
(APICER -(Associação Portuguesa das Indústrias de Cerâmica e de Cristalaria), 2014)
O processo de fabricação de placas cerâmicas consome uma grande quantidade de energia, maioritariamente energia térmica, que se obtém da combustão de gás natural. O aumento do custo deste combustível, assim como a situação ...
Preparation of feedstocks from nano/submicron-sized TiO2 particles to obtain photocatalytic coatings by atmospheric plasma spraying
(Elsevier, 2014-12)
Atmospheric plasma spraying (APS) has been proved useful in obtaining TiO2 coatings with effective photocatalytic activity. However, the influence of feedstock characteristics on photocatalytic activity has hardly been ...
Large scale synthesis of nanostructured zirconia-based compounds from freeze-dried precursors
(Elsevier, 2013)
Nanocrystalline zirconia powders have been obtained at the multigram scale by thermal decomposition of precursors resulting from the freeze-drying of aqueous acetic solutions. This technique has equally made possible to ...
Factors Controlling Properties of Ca-Mg, Ca-Er, Ca-Nd, or Ca-Y-Modified Aluminosilicate Glasses Containing Nitrogen and Fluorine
(John Wiley & Sons, 2013)
Glasses with composition (in eq.%) (30 − x)Ca:xM:55Si:15Al:80O:15N:5F have been prepared with different levels of substitution of Ca2+ cations by Mg2+, Y3+, Er3+, or Nd3+. The properties of these glasses are examined in ...
Delayed curvature and residual stresses in porcelain tiles
(Elsevier, 2013)
Most industrial porcelain tiles suffer changes in their curvature after firing: such process is known as delayed curvature. One of the hypotheses used to explain this phenomenon is based on the relaxation of residual ...
