I-Reaction-Bonded Silicon Carbide Crucibles: I-Revolutionizing Izinqubo Ze-Metallurgical Ezisezingeni Lokushisa Eziphezulu

I-Reaction bonded silicon carbideiziphambanozimelela impumelelo kubuchwepheshe be-refractory, obunikeza ukusebenza okungenakuqhathaniswa ezindaweni ezishisayo kakhulu. Lezi zitsha ze-ceramic ezithuthukisiwe sezibaluleke kakhulu kuyo yonke i-metallurgy, ukunemba kokusakaza, ubunjiniyela bemishini, nezimboni zokucubungula amakhemikhali, ziletha ukusebenza okuphakeme lapho izinto zendabuko kusilela khona.

Izinzuzo Eziyinhloko Zezobuchwepheshe

I-RBSC crucibles idlula i-alumina evamile kanye nozakwabo be-graphite ngokusebenzisa:

- I-thermal conductivity ehlukile (120–150 W/m·K ku-1000°C)

- I-coefficient yokunwetshwa kwe-thermal ephansi kakhulu (4.5×10⁻⁶/K)

- Ukumelana nokushaqeka okushisayo ukumelana nemijikelezo yokupholisa esheshayo engu-50+ (1600°C→25°C)

- I-Acid/alkali corrosion resistance (ukuhambisana kwe-pH 0–14)

- Ukuzinza kwe-oxidation emoyeni kuze kufike ku-1650°C

I-Metallurgical Mastery

Ekukhiqizeni insimbi ye-alloy kanye nokuncibilikiswa kwensimbi okungeyona ayoni (i-aluminium, ithusi, i-zinc), izinsimbi ze-RBSC zinika amandla:

- 20–30% amazinga okuncibilika ngokushesha ngokudluliswa kokushisa okulungiselelwe

- 99.95% ukugcinwa kokuhlanzeka kwensimbi kusetshenziswa izindawo ezingasasebenzi

- Kuncishiswe ukwakheka kwe-slag ngokunciphisa ukuhlukaniswa okushisayo

- Impilo yesevisi eyandisiwe (3–5× yinde kuneziphambano ze-clay-graphite)

Ukusakaza Okunembile Nezinhlelo Zokusebenza Zemishini

Izakhiwo ezihlukile zemishini yama-crucibles zisekela izidingo zezimboni ezinzima:

- Ukugcinwa kobuqotho besakhiwo ngaphansi kwengcindezi yemishini engu-15–20 MPa

- Ukuzinza kwe-dimensional okungaguquki (±0.1% ushintsho lwevolumu ku-1500°C)

- Ukucutshungulwa okungangcoliswa kwezingxenye zebanga le-aerospace

- Ukusebenza okuthembekile kumasistimu okusakaza we-centrifugal

Amakhemikhali Ukucubungula Excellence

I-RBSC crucibles ibhekana nezinselele ezibalulekile ekuhlanganiseni kwamakhemikhali:

- Ukuqukatha okuphephile kukasawoti oncibilikisiwe (isb, NaOH, KNO₃)

- Ukusebenza okuzinzile ekuphenduleni kwe-sulfidation / chlorination

- Ukumelana nokugqwala ngokumelene ne-HF kufika ku-800°C

- Ukulondolozwa kobumsulwa ekukhishweni kwesici somhlaba esingajwayelekile

Ezomnotho Zokusebenza

Nakuba izindleko zokuqala ziphakeme ngo-40–60% kuneziphambano zendabuko, izixazululo ze-RBSC ziletha:

- 70% ukunciphisa imvamisa esikhundleni

- 25–35% yokonga amandla ngokwenza ngcono ukusebenza kahle kokushisa

- 90% ukuphinda kusetshenziswe izinto ngokufakwa kabusha kwe-thermal

- Izidingo zokulungisa eziseduze noziro

Ukuqamba Okukhethekile Kwemboni

1. I-Titanium Alloy Production

- Imelana ne-Time esebenzayo iyancibilika ku-1700°C

- Ivimbela ukungcoliswa kwe-carbon pick-up

2. I-Battery Material Synthesis

- Inika amandla ukucutshungulwa kwe-cathode ye-LiCoO₂ efanayo

- Imelana ne-lithium salt corrosion

3. Ukukhula kwe-Crystal Semiconductor

- Igcina ukuhambisana kwe-vacuum ephezulu kakhulu

- Iqeda ukungcoliswa kwe-silicon carbide

Idizayini Yekusasa-Phambili

I-RBSC crucibles yesimanje ihlanganisa izici ezithuthukile:

- Izakhiwo ze-gradient porosity zokulawula ukungena kwegesi

- I-Nanoscale surface coatings ithuthukisa ukumelana ne-slag

- Izinzwa ezishumekiwe ezishisayo zokuqapha inqubo

Kusukela ocwaningweni lwesilinganiso saselabhorethri kuya ekukhiqizweni ngobuningi bezimboni, iziphambano ze-silicon carbide crucibles eziboshiwe ziyaqhubeka nokuchaza kabusha amandla okucubungula okushisayo. Inhlanganisela yabo eyingqayizivele yezakhiwo ezishisayo, ezomshini, kanye namakhemikhali zizibeka njengengxenye ebalulekile yokuzikhethela kwezinhlelo zokusebenza ezisezingeni eliphezulu zesizukulwane esilandelayo, ukushayela kahle kanye nokuthuthukiswa kwekhwalithi kuyo yonke imikhakha yokukhiqiza ethuthukisiwe.
