Lanthanumand the light lanthanides (cerium througheuropium) are more abundant than the heavy lanthanides (gadoliniumthroughlutetium). Thus, the individual light lanthanide elements are generally less expensive than the heavy lanthanide elements. Furthermore, the metals with evenatomic numbers(cerium,neodymiu...
FeCl3. The TiCl4is then reduced with moltenmagnesiumat about 800 °C (1,500 °F) in an atmosphere ofargon, and metallic titanium is produced as a spongy mass from which the excess of magnesium and magnesium chloride can be removed by volatilization at about 1,000 °C (1,800 °F). Th...
