The goal of this research was to obtain a chemically complex multicomponent
oxide with the A2B2O7 pyrochlore structure with nominal composition
(La1/7Sm1/7Nd1/7Pr1/7Y1/7Gd1/7Yb1/7)2(Sn1/3Hf1/3Zr1/3)2O7 that contains 10 different
cations in equiatomic amounts which was obtained by reacting metal nitrates (site
A) and metal chlorides (site B) with glycine during the combustion reaction. The
powder synthesized initially was found to be amorphous based on XRD analysis. To
convert the powder into a crystalline pyrochlore structure, the powder underwent
post-calcination at various temperatures ranging from 600–1500 °C. It was
discovered that the desired monophase pyrochlore structure (A2B2O7) was obtained
after calcination at 900 °C. To create a high-density ceramic pellet, the powder
calcined at 900 °C was subjected to pressureless sintering at 1650 °C for four hours
in the presence of air. The resulting pellet had a density of 97% of the theoretical
density and was free from an...y additives. This process likely caused the powder
particles to fuse together, creating a solid, dense pellet.
