Tsvagiridzo mamiriro eyakagadziridzwa silicon carbide ceramics

Recrystallizedsilicon carbide (RSiC) ceramicsvari ahigh-performance ceramic material. Nekuda kwekunaka kwayo kwekushisa kwekushisa, oxidation kuramba, corrosion resistance uye kuoma kwakanyanya, yakashandiswa zvakanyanya mundima dzakawanda, semiconductor kugadzira, indasitiri yephotovoltaic, mavira ekupisa uye michina yemakemikari. Nekuwedzera kuri kuita kudiwa kwezvinhu zvepamusoro-soro muindasitiri yemazuva ano, kutsvagisa uye kusimudzira kweyakagadziridzwa silicon carbide ceramics kuri kuwedzera.

1. Kugadzirira teknolojia yerecrystallized silicon carbide ceramics

Iyo tekinoroji yekugadzirira yakagadziridzwasilicon carbide ceramicskunyanya inosanganisira nzira mbiri: poda sintering uye vapor deposition (CVD). Pakati pavo, iyo poda sintering nzira ndeyekunyudza silicon carbide poda pasi pekushisa kwakanyanya nharaunda kuitira kuti silicon carbide zvimedu zviumbe dense chimiro kuburikidza nekupararira uye recrystallization pakati pezviyo. Iyo vapor deposition nzira ndeyekuisa silicon carbide pamusoro peiyo substrate kuburikidza nekemikari vapor reaction pakupisa kwakanyanya, nekudaro ichigadzira yakakwira-kuchena silicon carbide firimu kana zvikamu zvechimiro. Aya matekinoroji maviri ane zvawo zvakanakira. Iyo poda sintering nzira inokodzera kugadzirwa kwakakura uye ine mutengo wakaderera, nepo iyo vapor deposition nzira inogona kupa yakakwira kuchena uye denser chimiro, uye inoshandiswa zvakanyanya mumunda we semiconductor.

2. Zvinhu zverecrystallized silicon carbide ceramics

Hunhu hwakatanhamara hweyakagadziridzwa silicon carbide ceramics kuita kwayo kwakanakisa munzvimbo dzekushisa kwepamusoro. Nzvimbo yakanyunguduka yechinhu ichi yakakwirira se2700 ° C, uye ine simba rakanaka remagetsi pakupisa kwepamusoro. Uye zvakare, yakagadziridzwa silicon carbide zvakare ine yakanakisa oxidation kuramba uye corrosion kuramba, uye inogona kuramba yakagadzikana munzvimbo dzakanyanyisa makemikari. Naizvozvo, RSiC Ceramics yakashandiswa zvakanyanya muminda yehuni-yepamusoro-tembiricha, yakakwirira-tembiricha refractory zvinhu, uye makemikari michina.

Uye zvakare, yakagadziridzwa silicon carbide ine yakakwira yekupisa conductivity uye inogona kunyatso kuitisa kupisa, izvo zvinoita kuti ive yakakosha application kukosha mu.MOCVD reactoruye kupisa kupisa michina mu semiconductor wafer kugadzira. Yayo yakakwirira yekupisa conductivity uye kupisa kwekutya kupikisa kunovimbisa kushanda kwakavimbika kwemidziyo pasi pemamiriro akanyanya.

3. Mashandisirwo eminda yerecrystallized silicon carbide ceramics

Semiconductor kugadzira: Muindasitiri yesemiconductor, yakagadziridzwazve silicon carbide ceramics inoshandiswa kugadzira substrates uye zvinotsigira muMOCVD reactor. Nekuda kwekukwirira kwayo kwekushisa kwekushisa, corrosion resistance, uye high thermal conductivity, RSiC zvinhu zvinogona kuchengetedza kushanda kwakagadzikana munzvimbo dzakaoma dzemakemikari reaction, kuve nechokwadi chemhando uye goho rema semiconductor wafers.

Photovoltaic indasitiri: Muindasitiri yephotovoltaic, RSiC inoshandiswa kugadzira chimiro chekutsigira chekristaro kukura michina. Sezvo kukura kwekristaro kunofanirwa kuitwa pakupisa kwepamusoro panguva yekugadzira masero ephotovoltaic, kupisa kwekupisa kweiyo recrystallized silicon carbide kunovimbisa kushanda kwakasimba kwenguva refu kwemidziyo.

Kupisa-kupisa kwemoto: RSiC ceramics zvakare inoshandiswa zvakanyanya mumabira ekupisa, senge linings uye zvikamu zvevacuum furnaces, kunyunguduka kwevira uye zvimwe zvishandiso. Kupisa kwayo kutyisa kupikisa uye oxidation kuramba kunoita kuti ive imwe yezvinhu zvisingadzokerike mumaindasitiri ekupisa kwepamusoro.

4. Tsananguro yekutsvagisa yerecrystallized silicon carbide ceramics

Nekukura kuri kudiwa kwezvinhu zvepamusoro-soro, iyo yekutsvagisa nzira yerecrystallized silicon carbide ceramics yave kujeka zvishoma nezvishoma. Tsvakurudzo yenguva yemberi inotarisa pane zvinotevera zvinhu:

Kuvandudza kuchena kwezvinhu: Kuti zvizadzikise kuchena kwepamusoro zvinodiwa mu semiconductor uye photovoltaic minda, vaongorori vari kutsvaga nzira dzekuvandudza kuchena kweRSiC nekuvandudza tekinoroji yekuisa vapor kana kuunza midziyo mitsva, nekudaro ichiwedzera kukosha kwayo kwekushandisa munzvimbo idzi dzepamusoro-tech. .

Kunatsiridza microstructure: Nekudzora sintering mamiriro uye kugoverwa kwehupfu zvimedu, iyo microstructure yerecrystallized silicon carbide inogona kuwedzeredzwa, nekudaro ichivandudza mashandiro ayo emuchina uye kupisa kwekutya kusagadzikana.

Zvishandiso zvinoumba zvinhu: Kuti zvienderane nemamiriro ekushandisa akaomarara, vaongorori vari kuyedza kubatanidza RSiC nezvimwe zvinhu kuti vagadzire zvinhu zvakaumbwa zvine multifunctional zvivakwa, senge recrystallized silicon carbide-based composite zvinhu zvine yakakwirira kupfeka kuramba uye magetsi conductivity.

5. Mhedziso

Seyepamusoro-inoshanda zvinhu, recrystallized silicon carbide ceramics yakashandiswa zvakanyanya muminda yakawanda nekuda kweakanakisa zvivakwa mukupisa kwepamusoro, oxidation kuramba uye corrosion resistance. Tsvagiridzo yeramangwana inotarisa pakuvandudza kuchena kwezvinhu, kusimudzira microstructure uye kugadzira komputa inoshanda zvinhu zvinosangana nekukura kuri kuita maindasitiri. Kuburikidza neaya hunyanzvi hwekuvandudza tekinoroji, yakagadziridzwazve silicon carbide ceramics inotarisirwa kuita basa rakakura muminda yakawanda yepamusoro-soro.
