Xim dab tsi yog alumina?

Feem ntau hais lus, ntshiab, tsis tau alumina yog dawb.

Txawm li cas los xij, tustus nasCov ntaub ntawv uas peb ntsib hauv lub neej txhua hnub tuaj yeem nthuav tawm ntau cov xim nyob ntawm lawv daim ntawv ua kom huv, purity, particle loj, thiab impurities. Daim duab qhia txog kev kos npe hauv qab no luv luv piv txog kev sib raug zoo ntawm cov sib txawv ntawm alumina thiab lawv cov xim:

1. Lawm tshwm sim txhuas oxide (corundum)

Ntshiab -} al₂o₃ (ib leeg siv lead ua): tsis muaj xim thiab pob tshab, qhov no yog sapphire sapphire lossis dawb sapphire.

Thaum doped nrog impurities, nws tuaj yeem nthuav tawm ntau yam xim, uas yog vim li cas thiaj li muaj nuj nqis gemstones yog nrov nrov li no:

· Chromium: Liab, Ruby.

Ih Hlau thiab Titanium: Xiav, Sapphire (Sapphire tsis yog txwv rau xiav; corundum gemstones ntawm lwm cov xim kuj tseem hu ua sapphires).

Cov muaj lwm cov ntsiab lus lwm cov kuj tseem tuaj yeem tsim kom daj, ntsuab, ntshav, thiab lwm yam xim.

2. Cov khoom siv muaj alumina raw khoom

Smelting - Qib Qib Alumina: Feem ntau yog cov hmoov dawb xoob. Tsim los ntawm Bauxite ntawm cov txheej txheem bayer, nws yog cov khoom siv breaker rau cov electrolytic ntau lawm.

Siab - purity}}}}}}} сс trafine alumina: kuj feem ntau hmoov dawb, qhov txawv txav ntawm lub cev dawb. Siv nyob rau hauv precision ceramics, sapphire crystal kev loj hlob, thiab polishing cov neeg ua kom huv.

3. Siv Alumina

Ib qho tshwj xeeb kho alumina, feem ntau tsim nyob rau hauv pellets lossis block, yog dawb lossis me ntsis pinkish dawb. Nws yog feem ntau siv los ua adsorbent, desiccant, thiab catalyst cov cab kuj.

Lub ntsiab

Yog li, thaum ib tug neeg nug "dab tsi xim yogtus nas? "Cov lus teb zoo tshaj yog tias nws yog qhov tseem ceeb tshaj plaws dawb, tab sis ntuj gemstones tuaj yeem tshwm sim nyob rau ntau yam xim vim impurities, thiab cov khoom lag luam feem ntau yog dawb.
