Cerium

  At QSAM Inc., we provide high-purity cerium metal and compounds for diverse applications across industries. With the atomic number 58, cerium is a silvery rare earth metal that readily oxidizes in air. This ductile element has a density of 6.77 g/cm3 and melts at 798°C. It can exhibit +3 and +4 oxidation states, with +3 being the most stable.

  One major application of our cerium is in automotive catalytic converters, where it serves as an oxidation catalyst to convert harmful CO and NOx emissions into less hazardous CO2 and N2. Cerium oxide, also known as ceria, is utilized to polish glass surfaces like TV screens and mirrors, and to color and prevent discoloration of glass. As an alloying agent, cerium enhances the strength of aluminum and ductility of iron. In electronics, our cerium produces phosphors for displays and gets incorporated into semiconductor materials. Cerium oxide nanoparticles can also improve the efficiency of fuel cells and batteries. Additionally, cerium enables portable chemical oxygen generation for miners, divers and firefighters.

With its flexible oxidation states, cerium facilitates many essential oxidation-reduction reactions. At QSAM, we leverage our supply network to provide cost-effective, high-purity cerium to catalyze the critical reactions needed for your advanced products and technologies.
