Cov lus luv luv hais txog qhov xwm txheej tam sim no ntawm kev lag luam pob zeb diamond

Lub pob zeb "tus huab tais ntawm cov ntaub ntawv" vim nws lub cev zoo heev, tau tshawb nrhiav thiab txuas ntxiv hauv daim ntawv thov teb rau ntau xyoo lawm.Raws li ib qho kev hloov ntawm cov pob zeb diamond, cov pob zeb dag dag tau siv rau hauv thaj chaw xws li cov cuab yeej machining thiab kev xyaum ua rau ultra-wide band gap semiconductors, los ntawm laser thiab coj riam phom rau ci ntsa iab pob zeb diamond rings hauv poj niam txhais tes.Artificial pob zeb diamond tau dhau los ua ib feem tseem ceeb ntawm kev lag luam thiab kev lag luam hniav nyiaj hniav kub.

A. Cov ntaub ntawv yooj yim

Synthetic pob zeb diamond yog ib hom pob zeb diamond siv lead ua los ntawm txoj kev tshawb fawb los ntawm kev simulation ntawm cov khoom siv lead ua thiab kev loj hlob ib puag ncig ntawm ntuj pob zeb diamond.Muaj ob txoj hauv kev lag luam rau kev tsim cov pob zeb diamond loj - kub thiab kub siab (HTHP) thiab tshuaj vapor deposition (CVD).Los ntawm HPHT lossis CVD thev naus laus zis, pob zeb diamond dag tuaj yeem tsim nyob rau hauv ob peb lub lis piam, thiab cov tshuaj lom neeg muaj pes tsawg leeg, qhov cuam tshuam tsis zoo, txheeb ze ntom ntom, dispersion, hardness, thermal conductivity, thermal expansion, lub teeb kis tau tus mob, tsis kam thiab compressibility ntawm ntuj pob zeb diamond yog raws nraim. ib yam.Qib siab hluavtaws pob zeb kuj tseem hu ua pob zeb diamond cog qoob loo.
Kev sib piv ntawm ob txoj kev npaj yog raws li nram no:

Muaj daim ntawv thov ntawm pob zeb diamond

Cov xwm txheej ntau lawm ntawm pob zeb diamond ntuj yog qhov hnyav heev, yog li qhov tsis txaus yog qhov tseem ceeb, tus nqi siab txhua xyoo puag ncig, thiab tus nqi ntawm cov pob zeb loj hlob qis dua li ntawm cov pob zeb ntuj.Raws li "Lub Ntiaj Teb Pob Zeb Diamond Kev Lag Luam 2020-21" tso tawm los ntawm Bain Consulting, tus nqi muag khoom / muag khoom ntawm pob zeb diamond cog tau poob txij li xyoo 2017. Nyob rau lub quarter thib plaub ntawm 2020, tus nqi muag khoom ntawm lab-cultivated diamonds yog kwv yees li 35% ntawm uas ntawm ntuj pob zeb diamond, thiab tus nqi lag luam wholesale yog li ntawm 20% ntawm cov pob zeb diamond ntuj.Nws cia siab tias nrog kev ua kom zoo dua ntawm cov nqi tsim nyog, yav tom ntej kev lag luam tus nqi kom zoo dua ntawm kev cog pob zeb diamond yuav pom tseeb dua.

B. Kev lag luam saw

Artificial pob zeb diamond kev lag luam saw

Lub sab sauv ntawm hluavtaws pob zeb diamond kev lag luam saw yog hais txog kev muab cov ntaub ntawv raw xws li cov khoom siv ntau lawm thiab kev catalyst, nrog rau kev tsim cov pob zeb diamond ntxhib ntxhib.Tuam Tshoj yog tus tsim khoom tseem ceeb ntawm HPHT pob zeb diamond, thiab CVD pob zeb diamond tsim los kuj tseem txhim kho sai.Kev lag luam pawg tau tsim nyob rau hauv Henan xeev los ntawm cov neeg tsim khoom ntawm cov pob zeb diamond, suav nrog Zhengzhou Huacheng Pob Zeb Diamond Co., LTD., Zhongnan Pob Zeb Diamond Co., LTD., Henan Huanghe Cyclone Co., LTD., thiab lwm yam. thiab tsim cov khoom loj thiab siab purity dag pob zeb diamond (cultivated pob zeb diamond).Cov chaw lag luam sab saud paub txog cov txheej txheem tsim khoom ntawm pob zeb diamond ntxhib, nrog cov peev txheej muaj zog, thiab cov nqi muag khoom ntawm cov pob zeb diamond ntxhib yog ruaj khov, thiab cov nyiaj tau los kuj nplua nuj.
Qhov nruab nrab yog hais txog kev lag luam thiab kev ua cov khoom siv pob zeb diamond dawb paug, kev lag luam ntawm cov pob zeb hluavtaws ua tiav, thiab cov qauv tsim thiab Mosaic.Cov pob zeb me me tsawg dua 1 carat feem ntau yog txiav hauv Is Nrias teb, thaum cov carats loj xws li 3, 5, 10 lossis pob zeb diamond tshwj xeeb feem ntau txiav hauv Tebchaws Meskas.Tuam Tshoj tam sim no tau tshwm sim los ua lub ntiaj teb loj tshaj plaws txiav chaw, nrog Chow Tai Fook tsim 5,000 tus neeg txiav cog hauv Panyu.
Downstream feem ntau yog hais txog lub davhlau ya nyob twg khw muag khoom ntawm pob zeb diamond, kev lag luam thiab lwm yam kev lag luam txhawb nqa.Kev lag luam qib pob zeb diamond yog siv dav hauv aerospace, mechanical processing and manufacturing, petroleum exploration and other industries.Feem ntau ntawm cov pob zeb zoo nkauj zoo nkauj yog muag rau kev lag luam hniav nyiaj hniav kub raws li cov hniav nyiaj hniav kub qib cultivated diamonds.Tam sim no, Tebchaws Meskas muaj lub ntiaj teb kev lag luam loj tshaj plaws rau kev cog qoob loo thiab kev tsim kho pob zeb diamond, nrog rau kev muag khoom tiav.

C. Kev ua lag luam

Nyob rau hauv thaum ntxov xyoo, chav tsev tus nqi ntawm pob zeb diamond dag yog siab li 20 ~ 30 yuan ib carat, uas ua rau ntau yam tshiab manufacturing tuam txhab txwv.Nrog rau kev tsim cov thev naus laus zis ntau lawm, tus nqi ntawm cov pob zeb dag dag tau maj mam txo qis, thiab nyob rau xyoo tas los no, tus nqi tau poob qis dua 1 yuan ib carat.Nrog rau txoj kev loj hlob ntawm aerospace thiab tub rog kev lag luam, photovoltaic silicon wafers, semiconductors, hluav taws xob cov ntaub ntawv thiab lwm yam lag luam tawm tshiab, daim ntawv thov ntawm pob zeb diamond dag nyob rau hauv high-end manufacturing teb yog tas li nthuav.
Nyob rau tib lub sijhawm, vim muaj kev cuam tshuam ntawm ib puag ncig cov cai, kev lag luam kev lag luam loj (raws li kev tsim cov pob zeb diamond dag) tau pom qhov sib txawv ntawm thawj zaug poob thiab tom qab ntawd nce hauv tsib xyoos dhau los, nce mus rau 14.65 billion carats hauv 2018 thiab yog. cia siab tias yuav ncav cuag 15.42 billion carats hauv 2023. Cov kev hloov tshwj xeeb yog raws li hauv qab no:

Txoj kev tsim khoom tseem ceeb hauv Suav teb yog HTHP txoj kev.Lub peev xwm ntsia tau ntawm rau-sided laub xovxwm ncaj qha txiav txim siab lub peev xwm tsim khoom ntawm pob zeb diamond, suav nrog cov pob zeb cog qoob loo.Los ntawm ntau yam kev nkag siab ntawm pab pawg tshawb fawb, lub peev xwm uas twb muaj lawm hauv lub tebchaws tsis ntau tshaj 8,000 ntawm hom tshiab tshaj plaws ntawm rau-sab saum toj xovxwm, thaum tag nrho cov kev xav tau ntawm kev lag luam yog kwv yees li 20,000 ntawm hom tshiab tshaj plaws ntawm rau sab saum toj xovxwm.Tam sim no, txhua xyoo kev teeb tsa thiab kev ua haujlwm ntawm ntau lub tuam txhab loj hauv tsev pob zeb diamond tau mus txog qhov muaj peev xwm ruaj khov ntawm li 500 tshiab units, deb ntawm kev ua lag luam xav tau, yog li nyob rau lub sij hawm luv luv thiab nruab nrab, kev cog qoob loo hauv tsev ntawm pob zeb diamond kev lag luam muag khoom lag luam muaj txiaj ntsig zoo. tseem ceeb.
