Imyitwarire ya silicon karbideumusarababyerekana intambwe mu buhanga bwo kwanga, gutanga imikorere itagereranywa mubidukikije bikabije. Ibikoresho byabugenewe byateye imbere byabaye ingenzi cyane mubyuma bya metallurgie, gutara neza, gukora imashini, ninganda zitunganya imiti, bitanga imikorere isumba iyindi ibikoresho gakondo bigabanuka.
Ibyiza bya tekinike
Umusaraba wa RBSC urenze alumina isanzwe hamwe na grafite igereranya binyuze:
- Amashanyarazi adasanzwe (120–150 W / m · K kuri 1000 ° C)
- Ultra-low coefficente yo kwagura ubushyuhe (4.5 × 10⁻⁶ / K)
- Kurwanya ubushyuhe bwumuriro hamwe na 50+ byihuta bikonje (1600 ° C → 25 ° C)
- Acide / alkali irwanya ruswa (pH 0–14 ihuza)
- Oxidation ituje mu kirere kugeza kuri 1650 ° C.
Ubuhanga bwa Metallurgical
Mu gukora ibyuma bivangwa n'ibyuma no gushonga ibyuma bidafite fer (aluminium, umuringa, zinc), umusaraba wa RBSC urashobora:
- 20-30% byihuta byo gushonga binyuze muburyo bwiza bwo kohereza ubushyuhe
- 99,95% ibyuma bisukuye byifashishwa hejuru yubusa
- Kugabanya imiterere ya slag binyuze mumashanyarazi yagabanutse
- Ubuzima bwa serivisi bwagutse (3–5 × kurenza ibumba-grafite)
Gutera neza & Gukoresha imashini
Ibikoresho byihariye bya crucibles bishyigikira ibyifuzo byinganda:
- Uburinganire burambye bwubatswe munsi ya 15-20 MPa ya mashini
- Ihame rihoraho (± 0.1% ihinduka rya volumetric kuri 1500 ° C)
- Gutunganya kwanduza kubice byo mu kirere
- Imikorere yizewe muri sisitemu yo guterana
Gutunganya imiti
Umusaraba wa RBSC ukemura ibibazo bikomeye muri synthesis ya chimique:
- Kubika neza umunyu ushongeshejwe (urugero, NaOH, KNO₃)
- Igikorwa gihamye muri sulfidation / reaction ya chlorination
- Kurwanya ruswa kurwanya HF kugeza kuri 800 ° C.
- Kubungabunga isuku mu gukuramo isi idasanzwe
Ubukungu bukora
Mugihe ibiciro byambere biri hejuru ya 40-60% kurenza umusaraba gakondo, ibisubizo bya RBSC bitanga:
- 70% kugabanuka inshuro zisimburwa
- 25-35% yo kuzigama ingufu binyuze muburyo bwiza bwo gukoresha ubushyuhe
- 90% ibikoresho bisubirwamo binyuze mumashanyarazi
- Ibisabwa hafi ya zeru
Inganda zihariye
1. Umusaruro wa Titanium
- Ihangane Ti ikora Ti ishonga kuri 1700 ° C.
- Irinda gufata karubone kwanduza
2. Synthesis ya Batteri
- Gushoboza gutunganya cathode ya LiCoO₂
- Irwanya umunyu wa lithium
3. Gukura kwa Semiconductor Gukura kwa Crystal
- Igumana ultra-high vacuum ihuza
- Kurandura silicon karbide yanduye
Ibizaza-Imbere
Ibigezweho bya RBSC bigizwe nibintu byateye imbere:
- Gradient porosity structure ya gaze igenzurwa
- Ubuso bwa Nanoscale bwongera imbaraga zo kurwanya slag
- Byashyizwemo ibyuma byerekana ubushyuhe bwo gukurikirana inzira
Kuva muri laboratoire yubushakashatsi kugeza ku musaruro rusange w’inganda, umusemburo wa silicon karbide ingirakamaro ikomeza gusobanura ubushobozi bwo gutunganya amashyuza. Ihuza ryihariye ryubushyuhe, ubukanishi, nubumashini bibashyira nkibintu byingenzi byo guhitamo ibisekuruza bizaza-ubushyuhe bwo hejuru, gukoresha neza no kuzamura ireme mubikorwa byinshi byateye imbere.
