Mwala wa diamondi umalimidwa mu labotale yomwe imatengera mapangidwe achilengedwe a diamondi.Palibe kusiyana koonekeratu mu kristalo structural umphumphu, transparency, refractive index, kubalalitsidwa, etc. Synthetic diamondi ali ndi zonse zabwino thupi ndi mankhwala katundu wa diamondi zachilengedwe, kupanga izo ankagwiritsa ntchito mwatsatanetsatane kudula zida, kuvala zosagwira zipangizo, semiconductors ndi zamagetsi. zipangizo, otsika maginito kuzindikira, kuwala mazenera, amawumbidwe ntchito, biomedicine, zodzikongoletsera ndi zina zotero.

Chiyembekezo chakugwiritsa ntchito diamondi yopangira

Zida zodulira ndi makina olondola kwambiri Daimondi ndiye mchere wovuta kwambiri m'chilengedwe.Komanso, ali mkulu matenthedwe madutsidwe, mkulu kuvala kukana ndi kukhazikika mankhwala.Makhalidwewa amatsimikizira kuti diamondi ingakhalenso chinthu chodula kwambiri.Kupyolera mukupanga mwachinyengo diamondi yayikulu imodzi ya kristalo, makina opitilira muyeso amatha kukwaniritsidwa, omwe amatha kuchepetsa ndalama ndikuwongolera ukadaulo.

Optical ntchito

Daimondi imakhala ndi ma transmittance apamwamba mu bandi yonse ya kutalika kwa mafunde kuchokera ku X-ray kupita ku ma microwaves ndipo ndi chinthu chowoneka bwino kwambiri.Mwachitsanzo, MPCVD single crystal diamondi akhoza kupangidwa kukhala zenera kufala mphamvu kwa mkulu-mphamvu laser zipangizo, komanso akhoza kukhala zenera diamondi kwa kafukufuku danga.Daimondi ili ndi mawonekedwe a kukana kutenthedwa kwa kutentha, kukana kwa dzimbiri ndi kukana kwa makina ovala, ndipo idaphunziridwa ndikuyika pawindo la infuraredi, zenera la microwave, zenera la laser lamphamvu kwambiri, zenera lazithunzithunzi zamatenthedwe, zenera la X-ray ndi zina zotero.

Magawo ogwiritsira ntchito zida za quantum

Daimondi yomwe ili ndi vuto la nayitrogeni ili ndi mawonekedwe apadera amtundu, imatha kugwiritsa ntchito malo amtundu wa NV ndi mtengo winawake kutentha kwa firiji, ili ndi mawonekedwe a nthawi yayitali yolumikizana, kulimba kwa fluorescence, kuwala kowala kwambiri, ndipo ndi imodzi mwazonyamulira za qubit ndi kafukufuku wamkulu. mtengo ndi ziyembekezo.Mabungwe ambiri ofufuza adachita kafukufuku woyesera kuzungulira malo amtundu wa NV, ndipo zotsatira zochulukirapo za kafukufuku zakwaniritsidwa pazithunzi zowonera zamtundu wa NV, kafukufuku wowoneka bwino wa NV color center pa kutentha kochepa ndi chipinda. kutentha, ndi kugwiritsa ntchito ma microwave ndi njira zowunikira kuti azitha kupota, ndipo akwaniritsa ntchito zopambana pakuyezera kolondola kwambiri kwa maginito, kulingalira kwachilengedwe, ndi kuzindikira kwachulukidwe.Mwachitsanzo, zowunikira za diamondi siziwopa malo owopsa kwambiri komanso nyali zosokera, siziyenera kuwonjezera zosefera, ndipo zimatha kugwira ntchito pafupipafupi kutentha komanso kutentha kwambiri, popanda kufunikira kwa kuzirala kwakunja monga zowunikira za silicon.

Magawo amawu ogwiritsira ntchito

Daimondi ili ndi ubwino wokhala ndi zotanuka modulus, kachulukidwe kakang'ono komanso mphamvu zambiri, zomwe zimakhala zoyenera kwambiri popanga zida zothamanga kwambiri, zamphamvu kwambiri padziko lonse lapansi, ndipo ndi chinthu chabwino kwambiri popanga zida zomveka bwino.

Malo ogwiritsira ntchito makampani azachipatala

Kulimba kwa diamondi, kukana kuvala kwambiri, kugundana kochepa komanso kuyanjana kwabwino kwachilengedwe kumapangitsa kuti igwiritsidwe ntchito kwambiri m'malo olumikizirana ma prosthetic, ma valve amtima, ma biosensors, ndi zina zambiri, ndipo yakhala chinthu chofunikira komanso chofunikira kwambiri pamakampani amakono azachipatala.

Ntchito zodzikongoletsera

Daimondi yopangidwa ndi diamondi imafanana ndi diamondi yachilengedwe potengera mtundu, kumveka bwino, ndi zina zambiri, ndipo ili ndi maubwino odziwikiratu pamitengo yopangira ndi mitengo.Mu 2018, FTC yaulamuliro idaphatikizapo diamondi zolimidwa m'gulu la diamondi, ndipo diamondi zolima zidayambitsa nthawi yolowa m'malo mwa diamondi zachilengedwe.Ndi kuyimitsidwa ndi kuwongolera kwa miyezo ya diamondi yolimidwa, kuzindikira kwa diamondi zolimidwa pamsika wa ogula kukuchulukirachulukira chaka ndi chaka, ndipo msika wa diamondi womwe umalimidwa padziko lonse lapansi wakula mwachangu zaka ziwiri zapitazi.Malinga ndi lipoti la khumi lapachaka lamakampani a diamondi padziko lonse lapansi lomwe lidatulutsidwa limodzi ndi kampani yaku America yolangizira ndi Antwerp World Diamond Center, kuchuluka kwa diamondi padziko lapansi mu 2020 kudatsika mpaka 111 miliyoni carats, kuchepa kwa 20%, ndi kupanga diamondi nakulitsa anafika 6 miliyoni kwa 7 miliyoni carats, amene 50% mpaka 60% ya diamondi nakulitsa anapangidwa ku China ntchito kutentha ndi mkulu kuthamanga luso luso, ndi India ndi United States anakhala waukulu malo kupanga CVD.Kuphatikiza kwa odziwika bwino amtundu wa diamondi ndi mabungwe ovomerezeka ndi kuyesa kwawo kunyumba ndi kunja, chitukuko chamakampani olima diamondi chakhazikika pang'onopang'ono, kuzindikira kwa ogula kukukulirakulira chaka ndi chaka, ndipo diamondi zolimidwa zimakhala ndi malo akulu otukuka. msika wogula zodzikongoletsera.

Kuonjezera apo, kampani ya ku America LifeGem yazindikira luso la kukula kwa "diamondi yachikumbutso", pogwiritsa ntchito carbon kuchokera m'thupi la munthu monga zopangira (monga tsitsi, phulusa) kuti apange diamondi, mwa njira yapadera yothandizira achibale awo kusonyeza chikondi chawo kwa otayika. okondedwa, kupereka tanthauzo lapadera kwa diamondi zolimidwa.Posachedwapa, Hidden Valley Ranch, mtundu wotchuka wa saladi ku United States, adalembanso Dean Vandenbisen, katswiri wa sayansi ya nthaka ndi woyambitsa LifeGem, kuti apange diamondi ya makarati awiri kuchokera ku condiment ndikugulitsa.Komabe, zonsezi ndi nthano zabodza ndipo zilibe tanthauzo pakulimbikitsa kupanga pamlingo waukulu.

Munda wa Ultra-wide bandgap semiconductor

Ntchito yam'mbuyomu ndiyosavuta kuti aliyense amvetsetse, ndipo lero ndikufuna kuyang'ana kwambiri kugwiritsa ntchito diamondi mu semiconductors.Asayansi ku Lawrence Livermore National Laboratory ku United States adasindikiza pepala mu APL (Applied Physics Letters), lingaliro lalikulu ndiloti diamondi ya CVD yapamwamba ingagwiritsidwe ntchito pa "ultra-wide bandgap semiconductors" ndipo idzalimbikitsa kwambiri chitukuko cha mphamvu. ma grids, locomotives, ndi magalimoto amagetsi.

Mwachidule, danga lachitukuko cha diamondi yopangidwa ngati zodzikongoletsera ndi zodziwikiratu, komabe, chitukuko chake cha sayansi ndiukadaulo sichikhala ndi malire ndipo kufunikira kwake ndikwambiri.Kuchokera pamalingaliro a nthawi yayitali, ngati makampani opanga diamondi akufuna kuti apite patsogolo pang'onopang'ono m'kupita kwanthawi, ayenera kupangidwa kukhala chofunikira pa moyo ndi kupanga, ndipo pamapeto pake amagwiritsidwa ntchito m'mafakitale achikhalidwe ndi minda yapamwamba kwambiri.Pokhapokha poyesera momwe tingathere kukulitsa mtengo wake wogwiritsiridwa ntchito titha kukulitsa magwiridwe ake abwino kwambiri.Ngati kupanga kwachikhalidwe kukupitilirabe, kufunikira kumapitilirabe.Ndi chitukuko chowonjezereka cha ukadaulo wa diamondi kaphatikizidwe, kufunikira kwake kwakwezedwa mpaka pa "ndondomeko yadziko" ndi media ena.Masiku ano, ma diamondi achilengedwe omwe akuchulukirachulukira komanso ochepa, makampani opanga diamondi amatha kunyamula mbendera iyi.
