Pob zeb fianit: piav qhia, duab, interesting tseeb

LPI - tej zaum ib tug ntawm cov feem ntau nrov muaju siv nyob rau hauv hniav nyiaj hniav kub. Nyob rau hauv qhov tseeb, lub pob zeb nyhav zirconia - ib tug zoo zoo nkauj tshooj hluavtaws siv lead ua, uas ua rau dag tej yam kev mob. Kev zoo nkauj yog tsis inferior mus ntau tej yam ntuj tso gems, tab sis nws tus nqi yog ho qis.

Ntxoov ntxoo uas yuav emit fianit pob zeb, txiav txim los ntawm nws cov tshuaj nyob tus yeees. Thaum lub sij hawm lub thwmsim, uas twb muaj nyob rau hauv lub USSR nyob rau hauv 1960, zaum muaj twb tau sim los ua ib tug siv lead ua nrog tej khoom nyob rau hauv thiaj li thov nws nyob rau hauv lub lag luam thiab hauj nrhav. Thiab nws tau pom tias cov tau empirically fianit (pob zeb, uas nws yees duab saum toj no) fond connoisseurs ci ntsa iab decorations. Nyob rau hauv nws muaj pes tsawg leeg, txhua yam phianites - yog zirconia. Tshwj xeeb ua tso cai rau kom muab tau ib theem siab ntawm refraction ray, heev zoo xws li cov pob zeb diamond. Yog vim li cas nws puv tawm peculiar ua si ntawm lub teeb nyob rau hauv nruab hnub nrig thiab dag radiations.

Qhov no tej khoom vaj tse tej zaum kuj misleads tau txais kev pab tsis meej pem, uas ntseeg tau hais tias nyhav zirconia - nws yog ib lub pov haum. Nws sab nraud yam ntxwv, nws yeej muaj peev xwm sib tw nrog lub ntuj zoo zoo nkauj tshooj minerals. Tshwj xeeb tshaj yog nthuav mus saib cov kev ua si ntawm lub teeb nyob rau hauv lub ultraviolet. Artificially bred pob zeb nyhav zirconia ci ci xiav, daj, liab doog thiab lwm yam ntxoov.

Tshwj xeeb mloog yuav tsum tau lub npe ntawm tus siv lead ua. Nws yog nws leej twg nyob rau hauv Honor ntawm cov kev tshawb fawb lub tsev kawm ntawv, uas tau txais lub thawj kuaj - Physics koom haum ntawm lub Academy ntawm Sciences (FIAN).

Rau hnub tim, muaj ntau txoj kev uas tau precious fianites. Cov feem ntau - crystallization txoj kev. Lub thawv raus ib tug tshwj xeeb muaj pes tsawg leeg uas yog rhuab mus rau ib tug kub colossal - 3000 degrees. Ces sai txias, uas muaju tau tsim ntawm lub thawv terminals. Nyob ntawm seb lub additives nyob rau hauv lub hlau yuav tau txais ib tug ntau yam ntawm ntxoov. Los ntawm cov qauv no, lub pob zeb fianit feem ntau siv rau simulate topaz, xiav sapphire, ruby, ntsuab thiab violet chrysolites amethyst.

Undoubtedly, zus tau tej cov dag pob zeb - ib tug heev kim venture, tab sis nws yog ib ob peb lub sij hawm ntau yig tshaj pib cov kev tshawb fawb rau cov tshiab deposits ntawm diamonds, Corundum thiab lwm yam tseem ceeb hom. Uas yog vim li cas nyhav zirconia pob zeb tseem yuav ntev nyob twj ywm nyob rau hauv coob. Nws tej chaw tsis yog yooj yim: yuav pob zeb diamond hniav nyiaj hniav kub xav ntau, tab sis tsis yog txhua txhua, xws li ib tug purchase yuav them taus. Ib tug graceful phianites uas tsis muaj tsawg kaj ci thiab ntau yam ntawm cov xim muaj rau sawv daws. Niaj hnub nimno technologies pub rau tsim muaj tseeb masterpieces, siv lub "zirconium lub voos xwmfab."

Nyob rau hauv tas li ntawd, nqi siv lead ua thov nyob rau hauv cov tshuaj kev lag luam, electronics, precision machinery. Nws yog ib qho zoo heev insulator thaum uas tsis muaj thiab medium kub. Thiab nws ua ib tug conductive khoom thaum rhuab saum toj no 300 degrees. Kov lub pob zeb yog tsis yooj yim. Nyob rau hauv view ntawm lub fragility ntawm cov qauv feem ntau nws yog crumble. Yuav kom txo tau breakage, txiav npoo me ntsis nyob ib puag ncig tawm.
