Sigma-Aldrich Cerium (III) nitrate hexahydrate, 99% trace metals basis

Specifications:

Cerium (III) Nitrate Hexahydrate is the most common form of cerium nitrate and is widely used in synthetic chemistry and material science. This white-to-yellow crystalline salt is highly soluble in water, alcohol, and acetone, making it a versatile reagent in various laboratory applications. It has a low melting point (57°C) and thermally decomposes at relatively low temperatures, starting at 190°C and completing at 390-400°C.

As a trace metal reagent, it is primarily used as a source of cerium, especially in the synthesis of cerium oxide (ceria) for catalysis, solid oxide fuel cells, and the preparation of nanostructured materials like nano-cubes, nanotubes, and nanorods.

Cerium is one of the best-studied materials for catalysis, and its solubility and decomposition characteristics make cerium (III) nitrate hexahydrate an ideal reagent for hydrothermal reactions, sol-gel processing, co-precipitation, and calcination reactions.
