Kwincoko ende phakathi kwabantu kunye nezixhobo zokukhusela,i-silicon carbide ceramicsiphendula kwisiphakamiso esingunaphakade sokukhusela ukhuseleko ngelizwi elikhethekileyo. Le ceramic ibonakala iqhelekile grey-black yenza inguqulelo yanamhlanje yebali "lokuguquguquka ngokuthambileyo ngokuchasene nobulukhuni" kumasimi aphambili afana neshishini lomkhosi kunye ne-aerospace.
Ikhowudi yokukhusela ye-silicon carbide ceramics ilele kwihlabathi layo elincinci. Xa ikhuliswe ukuya kwi-nanoscale, izakhiwo ezingenakubalwa ze-tetrahedral zifana neebhloko ze-Lego ezidityanisiweyo ngokuchanekileyo, kwaye le nethiwekhi yendalo ye-dimensional emithathu inika imathiriyeli ngobulukhuni obungaqhelekanga kunye nokuqina. Xa imbumbulu ichaphazela umphezulu, esi sakhiwo sinokusebenza "njengentwasahlobo yemolekyuli", ukwahlula kunye nokunyibilikisa amandla empembelelo, ukuthintela ukujiya kunye nokuguqulwa kwezikrweqe zentsimbi zemveli kunye nokoyisa ubuthathaka bekeramics eziqhelekileyo ezithanda ukuqhekeka.
Xa kuthelekiswa nezixhobo zemveli ze-bulletproof, olu hlobo olutsha lwe-ceramic lubonisa "ubuntu obubini" obukhethekileyo. Ukuqina kwayo kunokukhuphisana nobedayimani, kodwa ubunzima bayo sisisinye kwisithathu kuphela sobentsimbi. Oku "kukhanya okunjengentsiba" kwenza ukuba izixhobo ezikhuselayo zifezekise ngokwenene impumelelo ekukhanyeni. Okumangalisa ngakumbi kukuba emva kokumelana neempembelelo ezibukhali, ayishiyi uxinzelelo olubulalayo lwangaphakathi njengesinyithi, kwaye olu phawu "lokungaxoleli" luphakamisa kakhulu ukuthembeka kwesixhobo.
Kwilabhoratri, ipleyiti ye-silicon carbide ceramic iphantsi kovavanyo lwe-ballistic. Xa iprojectile isondela ngesantya seemitha ezingama-900 ngomzuzwana, iintlantsi ezithi zigqabhuke xa zidibana zifana neziqhushumbisi eziboniswa kwihlabathi elincinane. Kulo mzuzwana, i-ceramic surface iqala ukubonisa "izakhono ze-Tai Chi": okokuqala, ngobunzima obuphezulu kakhulu, i-projectile iyancipha; emva koko, i-honeycomb structure isasaza i-wave shock macala onke; ekugqibeleni, ngokusebenzisa deformation yeplastiki ye-matrix, amandla ashiyekileyo afunxwa ngokupheleleyo. Le ndlela yokukhusela umaleko ngomnye utolika ngokucacileyo ubulumko bobuchwephesha bokhuseleko bale mihla.
Izazinzulu ngezinto zisaphonononga okunokwenzeka ngakumbi: ngoyilo lwe-bionics ukulinganisa ulwakhiwo oluthe kratya lwamaqokobhe, ukumilisela iintsinga ezinengqondo ezizivayo kwi-ceramic matrix, kunye nokuzama ukwenza imathiriyeli ibe namandla okuzilungisa. Ezi zinto zintsha aziqhubeli nje inkqubela phambili yetekhnoloji yokukhusela kodwa iphinda ichaze kwakhona intsingiselo yanamhlanje "yokhuseleko".
Ukususela kwizikrweqe zobhedu zamajoni amandulo ukuya kwiinano ceramics zanamhlanje, ukufuna kwabantu ukukhusela ukhuseleko akuzange kutshintshe. Ibali lophuhliso lwe-silicon carbide ceramics liyasixelela: Olona khuseleko lomelele luhlala luvela kweyona mithetho yendalo igqwesileyo, kwaye impumelelo kwizinto zesayensi ngumdaniso obalaseleyo onemithetho yendalo.
