Effect of secondary thermal treatment on crystallinity of spinel-type Co(Cr, Al)2O4 pigments synthesized by solution combustion route
(Elsevier, 2018-03)
The effect of a post-synthesis thermal treatment on CoCr2−2ΨAl2ΨO4 (0.0 ≤ Ψ ≤ 1.0) ceramic pigments synthesized by Solution Combustion Synthesis (SCS) has been studied. As-synthesized SCS pigments were treated at two ...
Study of lithium carbonate as sintering aid for tin oxide densification trough experimental designs: Main variables and microstructure changes
(Elsevier, 2022)
Tin oxide is one of the most extensively studied semiconductor materials due to its broad
field of applications. On the one hand, its high conductivity and its corrosion resistance are
the most remarkable properties. ...
