Cov kauj ruam ua haujlwm rau kev txiav txim siab silicon carbide cov ntsiab lus
Siv li 10g ntawm ib tug sawv cev silicon carbide qauv, muab tso rau hauv qhov cub ntawm 102 degree, coj nws mus rau hauv lub tshuab ziab khaub ncaws kom txias rau tom qab siv. Tshem tawm cov platinum zaub mov nyob rau hauv ib tug beaker ntawm distilled dej, rhaub nws nyob rau hauv ib qho cub, muab nws tso rau hauv lub desiccator kom txias rau tom qab siv. Nyob rau ntawm 10, {5}} degree hluav taws xob sib npaug, qhov raug hnyav hauv hluav taws xob, qhov tseeb: Daim ntawv (xov xwm hluav taws xob yuav tsum muaj ntsuas hnyav ua ntej siv). Ua ntej, moisten tus qauv hauv cov platinum tais nrog ib qho me me ntawm cov kua txob distilled, thiab 10 ml ntawm hydrofluoric acid, thiab muab tso rau hauv ib lub tshuab hluav taws xob ua kom yaj kom txog thaum lub Dawb haus luam yeeb ntawm cov sulphur trioxide ploj lawm. Tshem nws thiab txias nws me ntsis. Ntxiv 10 ml ntawm hydrogen acid thiab evaporate rau dryness ntawm ib qho hluav taws xob xuab zeb.
Ntxuav sab nraud phab ntsa ntawm cov platinum zaub mov, khaws cia rau hauv ib lub platinum acid acid, so kom yooj yim thiab feeb, yob platinum tais nrog lub khob pas nrig rau nchuav tag nrho cov Cov ntaub ntawv mus rau hauv lub beaker, yaug nws nrog dej distilled, thiab tsis txhob cia cov ntaub ntawv poob. Muab cov ntawv lim, lo rau ntawm phab ntsa ntawm funnel, nias lub funnel, thiab ua kom muaj dej noo, thiab ua kom muaj huab cua nyob ntawm daim ntawv thiab phab ntsa. Cia cov kua hauv lub beaker ntws raws lub iav pas nrig rau lub lim ntawv ntawv multure txheej rau kev lim. Sau cov kua lim thiab ntxuav ua kua hauv 250mL Volumetric flask, dilute rau cov nplai tom qab txias, thiab txuag nws rau ferric oxide. Tso cov ntawv lim thiab silicon carbide nyob rau hauv lub platinum tais, thiab tom qab ntawd tso nws nyob rau hauv ib muffle rauv taws ntawm 750 degree thiab hlawv nws rau 40 feeb. Hnov cov platinum tais uas tau txias thiab qhuav mus rau chav tsev kub, thiab thaum kawg sau cov ntaub ntawv.
