Descripción general

Detalles

This product is designed for advanced energy materials research, particularly in solid oxide fuel cells (SOFCs) and related electrochemical systems. Samarium-doped cerium oxide SDC20 (Sm0.2Ce0.8O1.9) features a fluorite-type crystal structure where Sm³⁺ substitution introduces oxygen vacancies, enhancing oxygen ion conductivity. It exhibits high thermal stability, mechanical hardness, and resistance to common acids and alkalis, making it suitable for high-temperature ceramic components, oxygen sensors, and catalyst supports. Technical characterization confirms a surface area of 54.1 m²/g and a particle size below 50 nm (45 nm measured), with low impurity levels (each below 100 ppm) and a loss on ignition of 0.3%. This material provides reliable performance for solid-state ion conduction and catalytic applications in energy conversion devices.

samarium doped cerium oxide SDC20, I .e. S'm'Ce. O', is doped with cerium oxide (CeO₂) as the base and samarium (Sm) at a mole fraction of 20%. In terms of crystal structure, Sm³ enters the crystal lattice of CeO₂ to form a fluorite-type structure. Due to the difference in ionic radii between Sm³ and Ce ³, oxygen vacancies will be introduced into the crystal lattice, which has an important impact on its performance.
[characteristics] high oxygen ion conductivity, high thermal stability, high hardness and wear resistance, not easy to react with common acid and alkali.
[use] solid oxide fuel cell (SOFC), oxygen sensor field, high temperature ceramic field, catalytic field (as catalyst carrier).
