Pyrolytic Boron Nitride Crucibles
Nhanganyaya
Pyrolytic BN kana PBN ipfupi ye pyrolytic boron nitride. Imhando yehexagonal boron nitride yakagadzirwa nekemikari vapor deposition (CVD) nzira, zvakare yakanyanyisa kuchena boron nitride inogona kusvika kupfuura 99.99%, inovhara kunenge kusina porosity.
Chimiro
Sezvatsanangurwa pamusoro, pyrolytic boron nitride (PBN) inhengo yehexagonal system. The intra-layer atomic spacing i1.45 uye inter-layer atomic spacing i 3.33, unova musiyano mukuru. Iyo yekumisikidza nzira yePBN ndeye ababab, uye chimiro chinoumbwa nekuchinjana B neN maatomu muchikamu uye pamwe neC axis, zvichiteerana.
Advantage
Iyo PBN zvinhu inoshingirira zvakanyanya kuhutachiwana hwekupisa uye ine yakanyanya anisotropic (yakananga inotsamira) yekufambisa yekudziya. Pamusoro pezvo, PBN inogadzira yepamusoro yemagetsi insulator. Dutu iri rakagadzikana muinert, kuderedza, uye oxidizing atmospheres kusvika 2800°C ne850°C, zvichiteerana.
Panyaya yechigadzirwa, PBN inogona kuumbwa kuita 2D kana 3D zvinhu senge crucibles, mabhoti, mahwendefa, wafers, machubhu, uye mabhodhoro, kana inogona kuiswa seyakapetwa kune graphite. Ruzhinji rwesimbi dzakanyungudutswa (Al, Ag, Cu, Ga, Ge, Sn, nezvimwewo), asidhi, uye inopisa ammonia zviri pakati pemamiriro ezvinhu apo PBN inoratidza kugadzikana kwekushisa kwakasiyana-siyana kana yakaputirwa pagraphite kusvika ku1700 ° C, inoramba kuvhunduka kwekushisa. , uye inodzivisa kuora kwegasi.
Product
PBN Crucible: Chigaba chePBN ndicho chigaba chakanyatsokodzera kugadzirwa kwekombonita semiconductor single crystals, uye haigoni kutsiviwa;
Muchirongwa cheMBE, ndicho chigadziko chakakodzera chekufefetedza zvinhu uye makomisheni;
Zvakare, iyo pyrolytic boron nitride crucible inoshandiswa senge evaporation element mudziyo muOLED mitsara yekugadzira.
PG/PBN Heater: PBN maheater anogona kushandiswa anosanganisira kudziyisa MOCVD, Metal heat, evaporation heat, superconductor substrate heat, sample analysis heat, electron microscope sample heat, semiconductor substrate heat, zvichingodaro.
PBN Sheet/Ring: PBN ine zvinhu zvakasarudzika patembiricha yepamusoro, sekuchena kwayo uye kukwanisa kushingirira kupisa kusvika 2300 °C muvacuum yakakwira-yepamusoro isingaori. Kunze kwezvo, haibudisi zvinosvibisa gasi. Aya marudzi ezvivakwa anobvumirawo PBN kuti igadziriswe kuita akasiyana ejiometri.
PBN Yakavharwa Graphite: PBN ine mukana wekuve unoshanda fluoride munyu wakanyoroveswa zvinhu izvo, kana zvaiswa kune graphite, zvinogona kumisa kusangana pakati pezvinhu. Saka, inowanzoshandiswa kuchengetedza zvikamu zvegraphite mumashini.
PBN Zvinhu mukuita kweTFPV
Kushandiswa kwezvinhu zvePBN muchirongwa cheTFPV(thin film photovoltaic) kunobatsira kuderedza mutengo wekuisa uye kuwedzera kushanda kwemaPV cells, zvichiita kuti magetsi ezuva aite shoma kugadzira senzira dzekabhoni.
Mhedziso
Maindasitiri mazhinji anowana kushandiswa kwakanyanya kwepyrolytic boron nitride. Kushandiswa kwayo kwakapararira kunogona kuverengerwa kune humwe hunhu hwayo hwakanakisa, kusanganisira kuchena kwakanyanya uye kushomeka kwekudzivirira. Iko kushandiswa kwepyrolytic boron nitride munzvimbo dzakasiyana-siyana kuchiri kuongororwa.
