The Tungsten/copper composites are commonly used for electrical and thermal objectives like heat sinks and lectrical conductors, propitiating an excellent thermal and electrical conductivity. These properties are dependents ...
Effect of PbO excess on the formation of lead magnesium niobate perovskite by the columbite method
(Elsevier B.V., 2004-03-15)
The effect of lead excess on the pyrochlore-type formation in Pb(Mg1/3Nb2/3)O-3 (PMN) powders has been investigated. The polymeric precursor method was used in the synthesis of the columbite in association to the partial ...

Synthesis and crystal structure refinement by th Rietveld method of an antimony-bearing titanite Ca(Ti0.6Al0.2Sb0.2)OSiO4
(Cambridge University Press, 2009-09)
A synthetic analogue, Ca(Ti0.6Al0.2Sb0.2)OSiO4, of antimony-bearing titanite of a composition similar to that found at St. Marcel-Praborna (Italy) was synthesized using ceramic methods and the crystal structure was refined ...
