I-micropowder ye-silicon carbide (SiC) iyaziwa kakhulu njengento ebalulekile ekukhiqizeni kobuchwepheshe obuphezulu, izinhlelo zamandla, kanye ne-ceramics ezithuthukisiwe. Ngobulukhuni obumangalisayo, ukuhanjiswa kokushisa, ukuzinza kwamakhemikhali, kanye nokumelana nokuguguleka, i-micropowder ye-SiC isekela ukuqeda ngokunemba, izinqubo ze-semiconductor, kanye nezingxenye zikagesi nezokushisa zesizukulwane esilandelayo.

Iyini i-Silicon Carbide Micropowder? — Izakhiwo Eziyinhloko

I-silicon carbide micropowderizici:

• Ubulukhuni be-Mohs obuphezulu (>9)

• Izici ze-semiconductor ze-bandgap ebanzi

• Ukushisa okuphezulu

• Ukumelana okuhle kakhulu kokugqwala kanye nokubola

• Ukubonakala kwe-infrared kanye nokuqina kokukhanya

• Ukwanda okuphansi kokushisa

• Ukungasebenzi kahle kwamakhemikhali

Lezi zimfanelo ezihlanganisiwe zenza i-SiC ibe yinto enemisebenzi eminingi efanelekile kokubili ukusetshenziswa okukhuhlayo kanye nokusebenzayo.

1. Izicelo Zokuqeda Ubuso Obune-Abrasive & Precision

Ngokomlando, ingxenye enkulu yemakethe ye-silicon carbide micropowder ibilokhu icutshungulwa ngokuhudula. I-SiC inikeza imiphetho yokusika ebukhali kanye namazinga okususa izinto ngokushesha uma kuqhathaniswa ne-alumina abrasives.

Ukusetshenziswa okuyinhloko kufaka phakathi:

• Ukugaya nokusika izinto eziqinile

• Ukupholisha okubonakalayo (ingilazi, isafire, amalensi)

• Ukuqeda isikhunta sensimbi

• Ukuhlela kwe-wafer ye-semiconductor

• Ukuqeda isibuko kanye ne-prism

I-SiC micropowder ivumela ukuqedwa kwendawo eyisicaba futhi engenasici, okubaluleke kakhulu kuma-optics athuthukile kanye nama-semiconductor substrates.

2. Izinhlelo Zokusebenza Ze-semiconductor Ne-Electronics

Ukushintshela kwe-semiconductor ezintweni zokwakha i-wide-bandgap kuye kwasheshisa isidingoI-SiC micropowderKuma-electronics anamandla, amadivayisi e-SiC adlula i-silicon ezindaweni ezine-voltage ephezulu, imvamisa ephezulu, kanye nezinga lokushisa eliphezulu.

Izinhlelo zokusebenza ezifanele zifaka:

• Ukupholisha i-wafer / ama-slurries e-CMP

• Ukulungiswa kwe-substrate ye-SiC wafer

• Ukupakishwa kwe-dielectric kanye ne-ceramic

• Izisabalalisi zokushisa ezishisayo zama-chips anamandla aphezulu

Izimoto zikagesi (ama-EV), ama-photovoltaics (ama-PV), izikhungo zedatha, kanye nengqalasizinda ye-5G yizona ezibangela ukukhula okukhulu kwezinto ezihlobene ne-SiC.

3. Izinto Zobumba Ezithuthukisiwe Nezinto Zokuphikisa

I-SiC micropowder isebenza njengesigaba sokuqinisa ekwakhiweni kwe-ceramic okusebenzayo kakhulu ngenxa yamandla ayo nokumelana nokushisa.

Izimakethe ezijwayelekile zifaka:

• Ifenisha nezinto zokushanela ze-kiln

• Ama-nozzle esishisi

• Izingxenye ezingagugi

• Izingxenye ze-turbine nezindiza

• Izingxenye zokuthwala kanye nezokupompa

Izimboni ezifana ne-metallurgy, i-aerospace, kanye nezinto ezidinga amandla ezigcina amandla angaphezu kuka-1400°C futhi zimelana nokuguguleka kwamakhemikhali—izakhiwo ezihambisana kakhulu ne-SiC ceramics.

4. Izicelo Zokugcina Ibhethri, Iseli Kaphethiloli kanye Nesitoreji Samandla

Ubuchwepheshe obusha bamandla ahlanzekile budala amathuba amashai-silicon carbidei-micropowder.

Izibonelo zifaka:

• Izithasiselo zokuqhuba ibhethri

• Izinto ze-anode ezihlanganisiwe

• Izitsha zobumba zamaseli kaphethiloli ezishisa kakhulu

• Izinhlelo zokushintshana nokuphatha ukushisa

Njengoba ukwamukelwa kwe-EV kushesha, ukuxhumana phakathi kwe-SiC yebanga le-semiconductor kanye nezinhlelo zokugcina amandla kuzoqhubeka nokukhula.

5. Ukukhiqiza Okungeziwe kanye Nezinto Ezihlanganisiwe

I-SiC micropowder manje idlala indima ekukhiqizweni okungeziwe (i-AM), ikakhulukazi ekuphrinteni kwe-ceramic 3D kanye ne-metal matrix composites.

Izinzuzo zifaka:

• Amandla okusebenza athuthukisiwe

• Isisindo esiphansi ngokuqina okukhulu

• Ukumelana nokuguguleka okuphezulu kanye nokushiswa kwe-oxidation

Lezi zinto zisebenza ngezindiza, ukuzivikela, kanye nezinhlelo zokusebenza zezimoto lapho ukuqina okulula kubalulekile khona.

6. Izinhlelo Zokusebenza Ezisebenzayo Zokukhanya Ne-Infrared

I-SiC inezakhiwo ezinhle zokukhanya kuma-wavelengths e-infrared, okwenza kube lula ukuyisebenzisa ku:

• Amafasitela e-IR

• Izingxenye zokushisa zebanga lesikhala

• Izinzwa kanye nezitholi

• Izimbozo ezivikelayo

Lezi zimakethe zidinga izinto ezikwazi ukusinda ekushaqekeni kokushisa kanye nemisebe yesikhala.

7. Izicelo Zobunjiniyela Bezemvelo Namakhemikhali

Ngenxa yokungasebenzi kahle kwamakhemikhali, i-SiC micropowder iphinde isekele izinhlelo zokuhlunga uketshezi lwezimboni kanye nokucubungula amakhemikhali.

Izibonelo zifaka:

• Ulwelwesi lokuhlunga lwe-ceramic

• Abathwali be-Catalyst

• Amavalvu nezivalo ezingamelani nokugqwala

• Ubuchwepheshe bamanzi angcolile ezimbonini

Ama-membrane e-ceramic e-SiC abhekwa njengethemba ezinhlelweni zokuhlunga ezinomthwalo omningi ngenxa yokungcola okuncane kanye nokuhlala isikhathi eside eshalofini.

Umbono Wemakethe Nezindlela Zesikhathi Esizayo

Ii-silicon carbideImboni kulindeleke ukuthi ikhule kakhulu eminyakeni eyishumi ezayo, iqhutshwa yilokhu okulandelayo:

• Ukwamukelwa kwe-semiconductor yezimoto zikagesi

• Amandla avuselelekayo kanye ne-elekthronikhi yamandla

• Ukukhiqizwa kwe-precision optics kanye ne-wafer

• Izitsha zobumba ezisebenza kahle kakhulu

• Izinto ezilula zezindiza

Abahlaziyi babikezela isidingo esikhulu sama-micropowder amancane acwebezelayo, ayindilinga, kanye nacwebezelayo njengoba izinhlelo zokusebenza zisezingeni eliphezulu.

Isiphetho

Kusukela ekusetshenzisweni kwe-abrasive okudlule kuya kubuchwepheshe be-semiconductor kanye namandla esizukulwane esilandelayo, i-silicon carbide micropowder ishintsha ibe yinto ebalulekile evumela ukusungulwa kwezimboni zanamuhla. Njengoba izimboni ziphishekela ukusebenza kahle okuphezulu, ukunemba, kanye nokuqina, indima ye-SiC micropowder izokhula kokubili emikhakheni eseyivele ikhona kanye neyamanje.
