OPALINE Cerium Oxide Compound 20 kg Pail
VERY HIGH PURITY, HIGHLY REFINED CERIUM OXIDE FOR VERY BRIGHT POLISHING OF PRECISION OPTICAL GLASS.
The abundant metallic elements of atomic number 57 through 71 (Lanthanide series) are known as rare earths, so called because they were originally thought to be rare. Cerium Oxide (atomic number 58) is the most abundant of the rare earth compounds. Cerium oxide in a water slurry is the best polishing agent for glass as regards to the rate of removal and ultimate surface finish.
