Alumina 92. Je to tvrd\u00e1 keramika, kter\u00e1 je tvo\u0159ena oxidem hlin\u00edku 92%. A ten druh\u00fd 8%? To je jen p\u00e1r n\u00e1hodn\u00fdch oxid\u016f, kter\u00e9 se tam hodily pro zaj\u00edmavost. Ale je\u0161t\u011b nez\u00edvejte - tenhle materi\u00e1l je v\u00e1\u017en\u011b p\u016fsobiv\u00fd.<\/p>\n
Za prv\u00e9, Alumina 92 je tvrd\u00fd. Mluv\u00edme tu o n\u00e1ro\u010dnosti na \u00farovni p\u0159e\u017eit\u00ed apokalypsy. Tato keramika se sm\u011bje extr\u00e9mn\u00edmu horku, odol\u00e1v\u00e1 korozi jako nic a z\u016fst\u00e1v\u00e1 siln\u00e1. Je to v podstat\u011b Termin\u00e1tor sv\u011bta materi\u00e1l\u016f.<\/p>\n
Mo\u017en\u00e1 si te\u010f \u0159\u00edk\u00e1te: \"Dob\u0159e, je to t\u011b\u017ek\u00e9. To je toho.\" Ale po\u010dkejte chv\u00edli. D\u00edky t\u00e9to hou\u017eevnatosti je Alumina 92 skute\u010dn\u00fdm pomocn\u00edkem ve v\u0161ech oborech. Pot\u0159ebujete n\u011bco, co se v\u00e1m neroztav\u00ed v \u0161\u00edlen\u011b hork\u00e9 pr\u016fmyslov\u00e9 peci? Alumina 92 se o v\u00e1s postar\u00e1. M\u00e1te nep\u0159\u00edjemn\u00fd chemick\u00fd roztok, kter\u00fd v\u0161echno pro\u017eere? Tato keramika \u0159\u00edk\u00e1 \"p\u0159ines to\". Dokonce ji strkaj\u00ed lidem do t\u011bla kv\u016fli ky\u010deln\u00edm implant\u00e1t\u016fm. Mluv\u00edme o univerz\u00e1lnosti!<\/p>\n
Poj\u010fme se na chv\u00edli pod\u00edvat trochu do hloubky. Na Mohsov\u011b stupnici tvrdosti (ano, to je skute\u010dn\u00e1 v\u011bc) m\u00e1 Alumina 92 sk\u00f3re 9 z 10. Diamant m\u00e1 10 bod\u016f. Tak\u017ee tenhle materi\u00e1l je tvrd\u0161\u00ed ne\u017e h\u0159eb\u00edky - je tvrd\u0161\u00ed ne\u017e t\u00e9m\u011b\u0159 v\u0161echno krom\u011b doslovn\u00fdch diamant\u016f. V\u00e1\u0161 kuchy\u0148sk\u00fd n\u016f\u017e by nem\u011bl \u0161anci.<\/p>\n
Hlin\u00edk Alumina 92 v\u0161ak nen\u00ed jen tvrd\u00fd - je tak\u00e9 skv\u011ble odoln\u00fd proti opot\u0159eben\u00ed. Proto je ide\u00e1ln\u00ed pro v\u011bci, kter\u00e9 se mus\u00ed pot\u00fdkat s velk\u00fdm t\u0159en\u00edm. Vzpome\u0148te si na strojn\u00ed sou\u010d\u00e1sti, kter\u00e9 se o sebe neust\u00e1le t\u0159ou. A poslechn\u011bte si tohle - pou\u017e\u00edv\u00e1 se v nepr\u016fst\u0159eln\u00fdch vest\u00e1ch. Jo, tahle keramika dok\u00e1\u017ee zastavit kulky. Jak\u00fd je to trik na ve\u010d\u00edrek?<\/p>\n
Nyn\u00ed si promluvme o teple. Hlin\u00edk 92 zvl\u00e1dne teploty, kter\u00e9 by v\u011bt\u0161inu v\u011bc\u00ed prom\u011bnily v lou\u017ee. Mluv\u00edme o teplot\u00e1ch p\u0159es 3000 \u00b0C. To je vy\u0161\u0161\u00ed teplota ne\u017e na povrchu Venu\u0161e. D\u00edky tomu se skv\u011ble hod\u00ed pro v\u011bci, jako je n\u00e1bytek do pec\u00ed - v\u00edte, v\u011bci, kter\u00e9 dr\u017e\u00ed jin\u00e9 v\u011bci, zat\u00edmco jsou vypalov\u00e1ny v super\u017ehav\u00fdch pec\u00edch.<\/p>\n
Ale po\u010dkejte, je toho v\u00edc! (P\u0159\u00edsah\u00e1m, \u017ee se v\u00e1m nesna\u017e\u00edm nic prodat.) Hlin\u00edk 92 tak\u00e9 skv\u011ble udr\u017euje elekt\u0159inu pod kontrolou. Je to takov\u00fd p\u0159\u00edsn\u00fd rodi\u010d sv\u011bta materi\u00e1l\u016f, kter\u00fd dohl\u00ed\u017e\u00ed na to, aby se elektrony chovaly slu\u0161n\u011b.<\/p>\n
Pro\u010d tedy tento z\u00e1zra\u010dn\u00fd materi\u00e1l nepou\u017e\u00edv\u00e1me na v\u0161echno? No, m\u00e1 to n\u011bkolik nev\u00fdhod. Za prv\u00e9, jeho v\u00fdroba nen\u00ed levn\u00e1. Proces zahrnuje va\u0159en\u00ed pr\u00e1\u0161kov\u00e9ho oxidu hlinit\u00e9ho p\u0159i teplot\u00e1ch, p\u0159i kter\u00fdch by se \u010dervenala i sopka. To nen\u00ed zrovna projekt na zahradu.<\/p>\n
Hlin\u00edk 92 m\u016f\u017ee b\u00fdt tak\u00e9 trochu kr\u00e1lovnou dramatu, pokud jde o n\u00e1hl\u00e9 n\u00e1razy. Jist\u011b, je velmi tvrd\u00fd, ale sta\u010d\u00ed ho spr\u00e1vn\u011b zas\u00e1hnout a m\u016f\u017ee prasknout. Proto nem\u00e1me tal\u00ed\u0159e Alumina 92. Dok\u00e1\u017eete si p\u0159edstavit, \u017ee byste si takovou desku upustili na palec u nohy? Au.<\/p>\n
V\u00fdroba t\u00e9to z\u00e1zra\u010dn\u00e9 keramiky je pom\u011brn\u011b n\u00e1ro\u010dn\u00fd proces. Za\u010dne se super\u010dist\u00fdm pr\u00e1\u0161kem oxidu hlinit\u00e9ho, p\u0159im\u00edch\u00e1 se do n\u011bj dal\u0161\u00ed materi\u00e1l a pak se tvaruje, jak se mu zachce. Pak p\u0159ijde ta z\u00e1bavn\u00e1 \u010d\u00e1st - v podstat\u011b ji upe\u010dou v troub\u011b rozp\u00e1len\u00e9 tak, \u017ee se v n\u00ed roztav\u00ed k\u00e1men. Je to jako pe\u010den\u00ed su\u0161enek, kdyby va\u0161e su\u0161enky vydr\u017eely n\u00e1vrat z vesm\u00edru.<\/p>\n
Pot\u00e9 je \u010dasto nutn\u00e9 hlin\u00edk 92 brousit nebo \u0159ezat do kone\u010dn\u00e9ho tvaru. To je asi tak snadn\u00e9, jak to zn\u00ed - pot\u0159ebuj\u00ed n\u00e1stroje s diamantov\u00fdm hrotem, aby ud\u011blali d\u016flek. Je to jako sna\u017eit se vy\u0159ezat sochu z opravdu tvrd\u00e9 keramiky.<\/p>\n
P\u0159esto\u017ee je pr\u00e1ce s hlin\u00edkem Alumina 92 nep\u0159\u00edjemn\u00e1, lid\u00e9 pro n\u011bj nach\u00e1zej\u00ed st\u00e1le nov\u00e9 vyu\u017eit\u00ed. Pou\u017e\u00edv\u00e1 se ve v\u0161em, od luxusn\u00edch palivov\u00fdch \u010dl\u00e1nk\u016f a\u017e po um\u011bl\u00e9 zuby. Kdo by to byl \u0159ekl, \u017ee stejn\u00fd materi\u00e1l, kter\u00fd se pou\u017e\u00edv\u00e1 v pr\u016fmyslov\u00fdch pec\u00edch, m\u016f\u017ee skon\u010dit ve va\u0161ich \u00fastech?<\/p>\n
V\u011bdci se neust\u00e1le sna\u017e\u00ed, aby byl Alumina 92 je\u0161t\u011b chladn\u011bj\u0161\u00ed. N\u011bkte\u0159\u00ed p\u0159id\u00e1vaj\u00ed drobn\u00e9 \u010d\u00e1stice, aby ho je\u0161t\u011b v\u00edce pos\u00edlili. Jin\u00ed se ho sna\u017e\u00ed vytisknout na 3D tisk\u00e1rn\u011b, proto\u017ee b\u011b\u017en\u00fd 3D tisk z\u0159ejm\u011b nebyl dost n\u00e1ro\u010dn\u00fd.<\/p>\n
Tak tady to m\u00e1te - Alumina 92 v cel\u00e9 sv\u00e9 kr\u00e1se. Je hou\u017eevnat\u00fd, v\u0161estrann\u00fd a pravd\u011bpodobn\u011b se nach\u00e1z\u00ed ve v\u00edce v\u011bcech kolem v\u00e1s, ne\u017e si mysl\u00edte. A\u017e budete p\u0159\u00ed\u0161t\u011b na ve\u010d\u00edrku a n\u011bkdo se zm\u00edn\u00ed o Alumina 92 (proto\u017ee to se st\u00e1v\u00e1 po\u0159\u00e1d, \u017ee?), m\u016f\u017eete ho oslnit sv\u00fdmi keramick\u00fdmi znalostmi. Jen se nepokou\u0161ejte demonstrovat t\u00edm, \u017ee upust\u00edte n\u011bjak\u00fd tal\u00ed\u0159ek Alumina 92 - mohl by se od\u0161t\u00edpnout a v\u00e1\u0161 hostitel by to pravd\u011bpodobn\u011b neocenil.<\/p>\n
Nakonec je Alumina 92 jako ten nen\u00e1padn\u00fd superhrdina, kter\u00fd se skr\u00fdv\u00e1 na o\u010d\u00edch. Mo\u017en\u00e1 nen\u00ed tak ok\u00e1zal\u00fd jako n\u011bkter\u00e9 jin\u00e9 materi\u00e1ly, ale nen\u00e1padn\u011b zachra\u0148uje situaci nes\u010detn\u00fdmi zp\u016fsoby. Tak\u017ee na Alumina 92 - a\u0165 je i nad\u00e1le neop\u011bvovan\u00fdm hrdinou sv\u011bta materi\u00e1l\u016f, a\u0165 je to jedna aplikace odoln\u00e1 proti korozi za druhou!<\/p>\n
