Doping txoj kev yog ib txwm muaj rau meltingScandium Inflmediate AlloysCov. Nws cuam tshuam nrog kev qhwv ib qho kev faib ua feem ntawm cov kev coj dawb huvhlau scandiumHauv txhuas, tom qab ntawd tov nws nrog molten aluminium hauv qab tiv thaiv, tuav nws rau lub sijhawm txaus, nplawm nws mus rau hauv cov hlau lossis txias tooj liab pwm kom tauScandium Inflmediate AlloysCov. Melting muaj peev xwm ua tau siv cov kev ua kom siab purity graphite lossis alumina crucibles, thiab cov hau kev cua sov tuaj yeem ua tau siv cov hluav taws kub ua ntu zus los yog cov hluav taws xob nruab nrab induction induction. Txoj kev no muaj peev xwm nyeem tau nruab nrab alloys muaj 2% mus rau 4%scandium.
Lub hauv paus ntsiab lus ntawm txoj kev doping yog yooj yim, tab sis lub ntsiab lus melting ntawmscandiumThiab txhuas txawv heev (SC yog 1541 ℃, A1 yog 660 ℃). Cov txhuas yaj yuav tsum tau ua kom sov siab dua, ua rau nws muaj kev sib xyaw nyob nruab nrab thiab nws tseem nyuaj kom tsis txhob muaj kev kub hnyiab ntawm scandium. Yuav kom ua tiav qhov no, txoj kev txhim kho yog kom sib tov thiab nias lub siab ua ntej thaum lub sij hawm npaj, thiab tom qab ntawd ntxiv rau hauv cov hlau molten. Cov decersant decomposes ntawm qhov kub, cia li crushing lub agglomerates, uas tuaj yeem tsim cov khaub ncaws tsis sib xws thiab txo cov roj hlawv ntawm lub siab yaj taw hlau. Tab sis tag nrho, tus nqi ntawm kev npajScandium Inflmediate AlloysSiv High-Purityscandium hlauRaws li cov khoom siv raw yog qhov tseem ceeb, uas yog qhov nyuaj rau cov neeg siv kev lag luam kom lees txais.
