Txoj kev doping yog ib txoj hauv kev rau melting scandium intermediate alloys. Nws koom nrog kev qhwv ib feem ntawm high-purity hlau scandium nyob rau hauv txhuas, ces sib tov nrog molten txhuas nyob rau hauv argon tiv thaiv, tuav nws rau ib tug txaus lub sij hawm, stirring nws kom huv si, thiab casti ...
