a mineral consisting of scandium yttrium silicate; a source of scandium.
dysprosium ,whether or not intermixed or alloyed with yttrium, scandium or other rare earth metals
Then the new technology in preparation of high purity scandium metal was proposed and its purification mechanism was discussed.
Lead scandium tantalate ceramics exhibit excellent dielectric, piezoelectric, and ferroelectric properties, but need rather higher sintering temperature and possess lower Curie temperature.
