Corundum yog lub pob zeb muaj txiaj ntsig los ntawm tus neeg muag khoom pom. Tus kws tshuaj yuav hais tias qhov no tsuas yog txhuas oxide xwb, cov xim uas tau muab los ntawm cov hlau, chromium, vanadium, titanium, thiab lwm yam. Impurities, uas yog kwv yees li 2% ntawm feem pua, hloov
aluminium nyob rau hauv crystal lattice ntawm cov ntxhia. Kuj ceeb tias, tib lub atoms / ions hauv cov ntxhia sib txawv tuaj yeem coj txawv txawv. Piv txwv li, chromium muab corundum xim liab, beryl (muaj feem xyuam nrog) ntsuab, thiab chrysoberyl ntsuab thaum sawv ntxov thiab liab thaum yav tsaus ntuj (alexandrite). Zoo li chameleon.
Corundum pob tshab xim xim hauv lub ntiaj teb cov hniav nyiaj hniav kub muaj nws cov npe. Cov zaub mov liab hu ua rubies, cov zaub mov ntsuab hu ua chlorosapphires, cov zaub mov xiav hu ua sapphires, thiab cov zaub mov tsis muaj xim hu ua leucosapphires. Nyob rau hauv ancient sij hawm, lub pob zeb liab hu ua Bengal amethysts, ntshav - violets, liab-violet - almandine sapphires. Pob tshab corundum, lub pob zeb xim txiv kab ntxwv, hu ua padparadscha, thiab daj-liab - padparadshah.
Nyob rau hnub qub, nyob rau hauv cov npe ntawm ntau yam sib txawv ntawm cov pob zeb no, cov jewelers thiab cov tub lag luam siv lo lus "oriental", uas yuav tsum tau hais txog qhov zoo ntawm lub pob zeb. Oriental pob zeb diamond, Oriental emeralds, Oriental aquamarines,oriental topazes thiab oriental chrysolites yog tag nrho cov corundums sib xws ntxoov. Yeej zoo tias cov npe no tsis siv tam sim no, txwv tsis pub yuav muaj kev tsis meej pem.
Qee zaum muaj pob zeb corundum nrog cov nyhuv asterism. Hauv cov qauv zoo li no, ib lub hnub qub rau- lossis kaum ob lub hnub qub pom, cov rays uas, thaum lub pob zeb tig, txav raws nws qhov chaw. Lub hnub qub sapphires thiab rubies muaj nuj nqis heev.
Corundum yog lub pob zeb tawv (ntawm Mohs nplai - 9). Nws yog surpassed nyob rau hauv hardness tsuas yog pob zeb diamond. Vim cov cuab yeej no, cov pob zeb uas tsis yog cov hniav nyiaj hniav kub yog siv los ua cov khoom siv abrasive (rau txiav thiab sib tsoo hlau, iav). Los ntawm txoj kev, lo lus "emery" yog ib lub ntsiab lus rau lo lus corundum. Cov pob zeb no tseem nyob hauv kev thov ua cov khoom siv refractory.
Tam sim no kev tsim khoom ntawm corundum tau tsim. Lawv tau los ntawm melting bauxite nrog hlau filings (raws li ib tug txo tus neeg sawv cev) nyob rau hauv hluav taws xob rauv. Feem ntau ntawm lawv yog siv nyob rau hauv technology, tsuas yog ob peb lub pob zeb mus rau hauv cov hniav nyiaj hniav kub. Piv txwv li, hluavtaws rubies yog siv nyob rau hauv kev lag luam saib raws li siv pob zeb, leucosapphires yog siv nyob rau hauv xov tooj cua-electronic kev lag luam.
Corundum yog mined tsuas yog hauv Is Nrias teb, Burma, Madagascar, Thaib, Sri Lanka. Kuj tseem muaj kev tso nyiaj hauv tebchaws Russia (hauv thaj chaw Krasnoyarsk, Primorye, Chelyabinsk Thaj Chaw, hauv Urals).
Corundum yog lub pob zeb uas tau lees paub los ntawm lithotherapists ntev. Thiab lawv siv nws nyob ntawm qhov xim. Nws ntseeg hais tias lub pob zeb xiavnormalize qhov muag siab. Liab - txhim kho cov ntshav khiav, qhib kev ua haujlwm ntawm cov qog, sib npaug ntawm cov metabolism. Violet - alleviate ntau neuralgia thiab kev puas siab puas ntsws. Txiv kab ntxwv - rejuvenate, txhim kho digestion.
Corundum (pob zeb) ua ib tug mascot zoo rau cov kws kho mob hlwb, kws kho mob, kws qhia ntawv, nrog rau txhua tus poj niam uas tau ua kev zoo siab rau hnub yug 40 xyoo.
