Hloov cov hlau muaj ntau yam ntawm siv , nrog qee qhov tseem ceeb hauv qab no: Hlau feem ntau ua rau cov hlau, uas muaj zog dua thiab yooj yim dua li cov hlau ntawm nws tus kheej. Nws yog dav siv nyob rau hauv cov khoom siv, cov cuab yeej, tsheb thiab ua ib qho catalyst hauv kev tsim cov ammonia.

Ib yam li ntawd, tib neeg nug, peb siv cov hlau hloov pauv rau dab tsi?

Hloov cov hlau yog siv raws li catalysts nyob rau hauv ntau txoj kev. Peb siv hlau nto nrog oxides los ua ammonia. Qhov no yog txoj kev pheej yig tshaj plaws los tsim cov ammonia, thiab siv ntau hauv cov chiv. Hlau nto ua tau adsorb cov ntsiab lus thiab compounds rau hauv nws tus kheej.

Ib yam li ntawd, cov kev hloov pauv dab tsi tuaj yeem siv los ua cov hlau? Titanium , chromium , thiab manganese yog cov hlau hloov pauv uas tau siv ntau hlau alloys los tsim corrosion-resistant, ruaj, thiab lub teeb yuag steel.

Ua raws li qhov no, kev siv cov hlau hloov pauv hauv tshuaj lom neeg yog dab tsi?

Lub Sijhawm Table

• Qee qhov kev hloov pauv hlau muaj kev siv dav,
• Hloov pauv hlau feem ntau tsim cov hlau tseem ceeb.
• Cov hlau hloov pauv feem ntau ua rau cov khoom siv zoo rau cov tshuaj tiv thaiv tshwj xeeb.
• Hlau hauv Haber txheej txheem.
• Manganese (IV) oxide nyob rau hauv decomposition ntawm hydrogen peroxide.

Dab tsi yog qhov tseem ceeb tshaj plaws ntawm kev hloov pauv hlau?

Cov khoom ntawm kev hloov pauv muaj xws li:

• muaj tus nqi loj / vojvoog piv;
• yog cov tawv thiab muaj siab ceev;
• muaj siab melting thiab boiling ntsiab lus;
• daim ntawv sib txuas uas feem ntau yog paramagnetic;
• qhia qhov sib txawv ntawm oxidation xeev;
• tsim xim ions thiab cov tebchaw;
• tsim cov tebchaw nrog kev ua haujlwm catalytic;
