CZ yog kab tias yog ib qho ntawm cov siv lead ua nrov tshaj plaws siv hauv cov hniav nyiaj hniav kub. Qhov tseeb, cubic zirconia yog cov khoom siv hluav taws xob muaj txiaj ntsig uas tau txais nyob rau hauv cov khoom siv dag zog. Kev zoo nkauj tsis yog qis dua ntau lub pov haum ntuj, tab sis tus nqi qis dua.

Qhov ntxoov ntxoo uas lub pob zeb zirconia tuaj yeem tawm tau yog txiav txim siab los ntawm nws cov tshuaj muaj pes tsawg leeg. Thaum lub sij hawm kev sim uas tshwm sim nyob rau hauv lub USSR nyob rau hauv 1960, cov kws tshawb fawb tau sim tsim ib tug crystal nrog tej yam khoom nyob rau hauv thiaj li yuav siv nws nyob rau hauv kev lag luam thiab technical innovation. Tab sis nws muab tawm hais tias lub cubic zirconia tau txais empirically (lub pob zeb, daim duab uas yog siab dua) poob rau hauv kev hlub nrog connoisseurs ntawm ci ntsa iab hniav nyiaj hniav kub. Los ntawm lawv cov muaj pes tsawg leeg, tag nrho cov cubic zirconia yog zirconium dioxide. Kev ua haujlwm tshwj xeeb tso cai rau kom tau txais qib siab ntawm kev cuam tshuam ntawm cov nqaj, zoo ib yam li pob zeb diamond. Tias yog vim li cas qhov kev ua si peculiar ntawm lub teeb tau txais nrog nruab hnub thiab hluav taws xob hluav taws xob.

Cov cuab yeej no qee zaum cuam tshuam cov neeg yuav khoom,leej twg ntseeg tias cubic zirconia yog pob zeb muaj nuj nqis. Raws li nws cov yam ntxwv sab nraud, nws yeej muaj peev xwm sib tw nrog cov khoom muaj txiaj ntsig zoo. Nws yog qhov txaus siab tshwj xeeb los saib xyuas kev ua si ntawm lub teeb hauv ultraviolet rays. Artificially bred cubic zirconia sparkles nrog ci xiav, daj, ntshav thiab lwm yam ntxoov ntxoo.

Lub npe ntawm cov siv lead ua tsim nyog tshwj xeeb. Nws muaj npe tom qab lub chaw tshawb fawb qhov twg thawj cov qauv tau txais - lub koom haum Physical Institute of Sciences (FIAN).

Hnub no, muaj ntau txoj hauv kev kom tau txais qhov cubic zirkonia muaj nuj nqis. Feem ntau yog txoj kev crystallization. Ib qho tshwj xeeb muaj pes tsawg leeg yog immersed nyob rau hauv lub thawv, uas yog rhuab mus rau ib tug colossal kub ntawm 3000 degrees. Tom qab ntawd nws yog txias txias, raws li qhov tshwm sim ntawm cov muaju yog synthesized ntawm lub thawv rods. Nyob ntawm cov additives nyob rau hauv lub alloy, ntau yam ntxoov ntxoo yuav tau. Ua tsaug rau txoj kev no, cubic zirconia feem ntau yog siv los xyaum topazes, xiav sapphires, rubies, ntsuab chrysolites thiab ntshav amethysts.

Undoubtedly, kev tsim cov pob zeb dag yog ib qho lag luam kim heev, tab sis nws yog ob peb zaug pheej yig dua li pib tshawb nrhiav cov pob zeb diamond tshiab, corundum thiab lwm yam pob zeb muaj txiaj ntsig. Yog li ntawd, cubic zirconia pob zeb yuav nyob twj ywm nyob rau hauv kev thov rau lub sij hawm ntev. Nws cov koob meej tuaj yeem piav qhia yooj yim: ntau tus neeg xav yuav cov hniav nyiaj hniav kub pob zeb diamond, tab sis tsis yog txhua tus tuaj yeem them taus xws li kev yuav khoom. Thiab elegant cubic zirconias tsis muaj tsawg ci ci thiab ntau yam ntxoov ntxoo muaj nyob rau hauv davcov neeg tuaj saib. Niaj hnub nimno technology tso cai rau koj los tsim ib tug tiag tiag masterpieces siv no "lub voos xwmfab ntawm zirconia".

Tsis tas li ntawd, cov khoom siv lead ua muaj txiaj ntsig yog qhov xav tau hauv kev lag luam tshuaj lom neeg, hluav taws xob, thiab kev ua haujlwm zoo. Nws yog ib qho zoo heev insulator ntawm qis thiab nruab nrab kub. Thiab nws dhau los ua cov khoom siv hluav taws xob thaum kub siab tshaj 300 degrees. Nws tsis yooj yim rau kev ua cov pob zeb no. Vim lub fragility ntawm cov qauv, nws feem ntau crumbles. Txhawm rau txo brittleness, cov npoo txiav yog me ntsis sib npaug.
