Bayan Obo mixed RE concentrate is the largest RE source in the world.RE elements occur dominantly in bastnaesite and monazite.
Long-persistent phosphorescence(LPP)materials have a great potential at the device applications as displays in dark environment,detection of high-energy rays,vivo imaging and so on.
Rare Earth Elements(REEs)have unique physicochemical properties that make them essential elements in many high-tech components,such as electric vehicle,power generator,MRI,screen display,hydride batte
Now rare earth has been widely introduced in heat-resistant steel.For example,in 253MA steel,cerium combined with silicon improves the oxidation resistance and erosion corrosion resistance.
Bastnaesite is a main kind of rare earth resources in which cerium accounts for more than 50%of the total rare earths.
Organometallic compounds of the rare earth elements have shown many interesting small molecule activation reactions,including hydrocarbon C-H bond cleavage,in the last 30 years.
Apatite is an important host mineral in igneous and metamorphic rocks for production of phosphate fertilizers and phosphoric acid.Deposits of apatite ores are the major source for rare earth elements(
Mid-heavy rare earths are of great significance in many strategic fields from superior property materials to large scale high-tech devices.
