Likopo tsa Sesole: Ho Sireletsa Maphelo Ntoeng
Ka mashome a lilemo, mabotho a sesole a 'nile a batla thepa e leka-lekaneng tšireletso le ho tsamaea. Lihlomo tsa tšepe tsa setso, leha li sebetsa hantle, li eketsa boima bo boholo likoloing le basebetsing. Li-ceramic tsa silicon carbide li rarollotse bothata bona. Ha li sebelisoa litsamaisong tsa lihlomo tse kopaneng—hangata li koahetsoe ka thepa e kang polyethylene kapa aluminium—li-ceramic tsa SiC li ipabola ho sitiseng le ho hasanya matla a likulo, li-shrapnel le likotoana tse phatlohang.
Likoloi tsa sesole tsa sejoale-joale, lipoleiti tsa lihlomo tsa 'mele le litulo tsa helikopthara li ntse li eketsa ho kenyelletsa liphanele tsa letsopa tsa SiC. Mohlala, lihelmete tsa ntoa tsa moloko o latelang oa Sesole sa US li sebelisa metsoako e thehiloeng ho SiC ho fokotsa boima ba 'mele ha li ntse li boloka tšireletso khahlanong le lithunya. Ka mokhoa o ts'oanang, lisebelisoa tsa lihlomo tsa letsopa tse bobebe bakeng sa likoloi tse hlometseng li ntlafatsa ho tsamaea ntle le ho beha polokeho kotsing.

Matlotlo a tšoanang a etsang hore liserami tsa SiC e be tsa bohlokoa ntoeng joale a sebelisoa bakeng sa tšireletso ea baahi. Ha litšenyehelo tsa tlhahiso li ntse li fokotseha, liindasteri li sebelisa "serami sena se phahameng" ka litsela tse iqapetsoeng:
1. Lihlomo tsa Likoloi: Batsamaisi ba maemo a holimo, bo-ralipolotiki le likoloi tsa VIP joale ba sebelisa liphanele tse sirelelitsoeng ka letsopa tsa SiC bakeng sa ho hanyetsa likulo, tse kopanyang mabothobotho le tšireletso.
2. Lifofane le Mabelo: Lihlopha tsa Formula 1 le baetsi ba lifofane ba kenya lipoleiti tse tšesaane tsa letsopa la SiC ka likarolo tsa bohlokoa ho itšireletsa khahlanong le litšusumetso tsa lithōle ka lebelo le phahameng.
3. Polokeho ea Liindasteri: Basebetsi ba libakeng tse kotsi (mohlala, merafong, mosebetsing oa tšepe) ba roala lisebelisoa tse sa seheng tse matlafalitsoeng ka likaroloana tsa ceramic tsa SiC.
4. Lisebelisoa tsa Elektroniki tsa Bareki: Tšebeliso ea liteko e kenyelletsa mabokose a li-smartphone a tšoarellang haholo le mabokose a sa futhumatseng bakeng sa libeteri tsa likoloi tsa motlakase.
