ስለ Cerium
Cerium is a soft, silvery, ductile metal about as common as copper. It can switch between +3 and +4 oxidation states. Cerium oxide is an important catalyst.
ፕሮግራሞች
Catalytic converters, glass polishing, self-cleaning ovens, lighter flints, and UV-absorbing glass.
ሐቅ
Despite being called 'rare earth,' cerium is more abundant in Earth's crust than copper, lead, or tin.
