TaC Coated Crucible yeCrystal Kukura
Semugadziri weTaC Coated Crucible anotungamira uye fekitori muChina, Semixlab TaC Coated Crucible mudziyo wekupisa unoshanda zvakanyanya wakagadzirirwa maitiro ekukura kwekristaro imwe chete, kusanganisira SiC PVT, GaN thermal growth, sapphire. Ine Tantalum Carbide coating yakakora uye isina makemikari inoshandiswa pagrafiti ye-isostatic yakachena kwazvo, crucible iyi inodzivirira zvakanyanya ngura, oxidation, uye carbon evaporation pasi pekupisa kwakanyanya. Tinogamuchira mibvunzo yenyu yakawanda.
tsananguro
Munzvimbo dzinokura dzine makristaro rimwe chete—ingava yekutakura vapor physical SiC (PVT), GaN ammonothermal processing, sapphire (Al₂O₃) Kyropoulos/Czochralski nzira—kugadzikana uye kuchena kwecrucible kunotsanangura mhando yepamusoro yeboule rinokura. Semixlab's Tantalum Carbide Coated Crucible yakagadzirwa zvakanangana nenzvimbo idzi dzinokura dzine tembiricha yakakwira uye dzine makemikari akasimba, ichipa kufanana kwakanyanya kwekupisa, kusvibiswa kushoma, uye hupenyu hwakareba kana tichienzanisa ne graphite yechinyakare kana refractory metal crucibles.
Pakati pechigadzirwa chedu pane chifukidziro chakafanana cheTantalum Carbide (TaC) chakakora, chakaiswa pagrafiti ye-isostatic yakachena kwazvo. TaC, ine nzvimbo yayo yekunyunguduka iri pamusoro pe3880°C, kumanikidzwa kwemhepo kwakaderera zvakanyanya, uye kusagadzikana kwemakemikari kunoshamisa, inoramba yakagadzikana munzvimbo dzinokura zvakanyanya - makamuri ePVT ane kabhoni yakawanda, maGaN reactor ane ammonia yakawanda, kana maovheni esapphire ane oxygen. Izvi zvinobvumira crucible kuchengetedza hunhu hwayo uye kudzvinyirira maitiro eparasite ayo aizounza tsvina, kuderedza goho rekristaro, kana kukanganisa minda yekupisa yakakosha kumodology ye ingot.
Kuti SiC PVT ikure, mukati meTaC-coated pamusoro payo zvinoderedza zvakanyanya graphite evaporation uye zvinodzivirira kusvibiswa kwekabhoni kwembeu nezvinhu zvinochaja. Coating iyi inowedzerawo kutamiswa kwekupisa nemwaranzi, ichivandudza kugadzikana kwekushisa kweaxial uko kunodzora zvakananga kugadzikana kweSiC polytype, dislocation density, uye boule diameter scalability.
Mhedzisiro yeTaC Coated Crucible yeSiC Single Crystal Growth
Mukukura kwekristaro yeGaN, TaC haikwanise kurwisa ngura yakanyanya pasi peammonia inokonzeresa kuti ishande kwenguva refu ine thermal conductivity yakasimba uye kusanyanya kuora kwepasi, zvichitsigira kufanana kwakanyanya kwekristaro.
Munguva yekukura kwesafire, chifukidziro ichi chinoshanda sechidziviriro kubva pakuoxidation kwegraphite uye chinodzivirira Al₂O₃-reactive interactions izvo zvinogona kukonzera kusvibiswa kwe crucible kana kusvibiswa kwekunyunguduka. Mukukura kweGaAs, kusagadzikana kwemakemikari kweTaC kunoderedza maitiro ane chekuita ne arsenic ukuwo kuchichengetedza nzvimbo yakachena yekunyunguduka, zvichivandudza kufanana kwemagetsi uye kuderedza kuumbwa kwezvikanganiso.
Maitiro ekugadzira eSemixlab anovimbisa huwandu hwemachira, kufanana kweukobvu, simba rekunamatira, uye kuramba kupisa kwakakodzera kushanda kwenguva refu kwemasekonzi akawanda. Chikero chega chega chinoongororwa nemetrology yehukuru, kuongororwa kwekuvimbika kwemachira, uye kuyedzwa kwekushushikana kwepamusoro-soro kuti zvienderane nezvinodiwa zvevagadziri vemichina yekukura kwekristaro yepamusoro.
