I''ve been hearing a lot in the media about how important rare earth metals are (from the economic standpoint of China limiting their export), but what do some of them actually do that makes them so essential that can''t be done with more common elements like silicon…

Rare Earth Elements. Cerium is the most abundant of the rare earths. It is characterized chemically by having two valence states , the +3 cerous and +4 ceric states. The ceric state is the only nontrivalent rare earth ion stable in aqueous solutions, making it strongly acidic and moderately toxic, as well as a strong cerous state closely resembles the other trivalent rare earths.

Scientists have opened a door to faster, cheaper telecommunications after proving a new link between silicon chips and ''rareearth'' metals used in internet signalling.

tend to improve with the addition of rareearth oxides to silicon nitride ceramics. A number of studies about the influence of rareearth oxides as sintering aids of silicon nitride were performed in 80s, 90s and 00s. Among these, Sanders et al.[7] investigated the effect of adding SiO 2 together with Y 2O 3, CeO 2, La 2O 3 or Sm 2O
