Vai esat k\u0101dreiz sakodis k\u0101du cietu priek\u0161metu un uztraucies, ka varat saskald\u012bt zobu? Vai esat br\u012bn\u012bjies, k\u0101p\u0113c da\u017ei na\u017ei paliek asi ilg\u0101k nek\u0101 citi? Tie\u0161i \u0161eit n\u0101k talk\u0101 cirkonija keramika - \u0161is nenov\u0113rt\u0113tais sp\u0113ks, kas ir iztur\u012bgs, sp\u012bd\u012bgs un par\u0101d\u0101s visda\u017e\u0101d\u0101kaj\u0101s negaid\u012bt\u0101s viet\u0101s. T\u0101 ir izgatavota no cirkonija dioks\u012bda, kas ir izdom\u0101ts veids, k\u0101 pateikt, ka t\u0101 ir ieg\u016bta no elementa cirkonija, ko ieg\u016bst no t\u0101diem miner\u0101liem k\u0101 cirkons. Pirmo reizi ar to sask\u0101ros, kad iepirka jaunu pulksteni; t\u0101 apmale bija no cirkonija, iztur\u012bga pret skr\u0101p\u0113jumiem un mirdzo\u0161a k\u0101 jauna pat p\u0113c gadiem n\u0113s\u0101\u0161anas. Tas mani aizr\u0101va, lai uzzin\u0101tu vair\u0101k par to, k\u0101 \u0161is materi\u0101ls apvieno dimanta ciet\u012bbu ar re\u0101lu praktiskumu.<\/p>\n
Cirkonija sakaus\u0113jums izce\u013cas ar to, ka tas ir \u013coti iztur\u012bgs un elast\u012bgs. P\u0113c Mosa ciet\u012bbas skalas t\u0101 ciet\u012bba ir aptuveni 8,5, kas noz\u012bm\u0113, ka t\u0101 ir l\u012bdz\u012bga saf\u012bram un var iztur\u0113t triecienus, viegli nesal\u016bstot. Slepen\u0101 m\u0113rce ir \"transform\u0101cijas r\u016bd\u012b\u0161ana\" - kad rodas spriegums, krist\u0101la strukt\u016bra nedaudz main\u0101s, absorb\u0113jot ener\u0123iju un nov\u0113r\u0161ot plaisas. Tas ir gandr\u012bz k\u0101 materi\u0101ls c\u012bn\u0101s pret\u012b. Turkl\u0101t tas tikpat k\u0101 nevad\u012bs siltumu, nekait\u0113s pret koroziju un nerea\u0123\u0113s ar \u0137imik\u0101lij\u0101m, padarot to \u012bpa\u0161i dro\u0161u saskarei ar \u0137ermeni. Tom\u0113r neapstr\u0101d\u0101ts cirkonija oks\u012bds var b\u016bt smalks; tas pie liela karstuma maina f\u0101zes, t\u0101p\u0113c m\u0113s to p\u0101rkl\u0101jam ar t\u0101d\u0101m viel\u0101m k\u0101 itrijs vai magn\u0113zijs, lai to nostiprin\u0101tu stabil\u0101 form\u0101. Bez t\u0101 tas temperat\u016bras sv\u0101rst\u012bbu ietekm\u0113 izplestos un saplais\u0101tu.<\/p>\n
Ar\u012b v\u0113sture ir diezgan interesanta. Cirkonijs tika paman\u012bts jau 1700. gad\u0101 d\u0101rgakme\u0146os, bet cirkonijs k\u0101 iztur\u012bga keramika s\u0101ka pla\u0161i izplat\u012bties tikai 70. gados. K\u0101ds austr\u0101lie\u0161u zin\u0101tnieks Rons Garvijs (Ron Garvie) izdom\u0101ja, k\u0101 padar\u012bt to iztur\u012bgu, nod\u0113v\u0113jot to par \"keramikas t\u0113raudu\", jo tas ir l\u012bdz\u012bgs met\u0101la smilt\u012bm, bet bez svara. M\u016bsdien\u0101s to ra\u017eo, pres\u0113jot cirkonija oks\u012bda pulveri form\u0101s un cepot to nepr\u0101t\u012bgi augst\u0101 temperat\u016br\u0101 proces\u0101, ko sauc par sa\u0137epin\u0101\u0161anu. Izejmateri\u0101lu ieg\u016b\u0161ana nav pastaiga park\u0101 - liel\u0101k\u0101 da\u013ca tiek ievesta no Austr\u0101lijas vai Dienvid\u0101frikas, un t\u0101 ir d\u0101rga, jo ir nepiecie\u0161ama att\u012br\u012b\u0161ana.<\/p>\n
Tikl\u012bdz s\u0101ksiet mekl\u0113t, visur atrad\u012bsiet cirkoniju. Zob\u0101rstniec\u012bb\u0101 tas maina sp\u0113les noteikumus: kro\u0146i un tilti\u0146i, kas imit\u0113 \u012bstos zobus, ir \u013coti iztur\u012bgi, un nav j\u0101uztraucas par aler\u0123ij\u0101m pret met\u0101lu. Mans zob\u0101rsts jau pirms vair\u0101kiem gadiem p\u0101rg\u0101ja uz tiem, un pacientiem pat\u012bk, ka tie ir dabiski. Medic\u012bn\u0101 t\u0101s izmanto loc\u012btavu prot\u0113z\u0113s, piem\u0113ram, g\u016b\u017eas un ce\u013cgalu loc\u012btav\u0101s - t\u0101s kalpo vair\u0101k nek\u0101 20 gadus ar minim\u0101lu nolietojumu. Virtuves profesion\u0101\u013ci saj\u016bsmin\u0101s par cirkonija asme\u0146iem; tie m\u016b\u017e\u012bgi notur malas un ner\u016bs\u0113 un neveido traipus. Kas attiecas uz mirdzumu, kubiskais cirkonijs p\u0101rliecino\u0161i atdarina dimantus, bet augst\u0101k\u0101s klases versijas izmanto luksusa pulkste\u0146os un juvelierizstr\u0101d\u0101jumos, lai ieg\u016btu nep\u0101rsp\u0113jamu sp\u012bdumu. No tehnisk\u0101 viedok\u013ca tas ir automa\u0161\u012bnu sk\u0101bek\u013ca sensoros, degvielas elementos, kas ra\u017eo za\u013co ener\u0123iju, un pat izolatoros s\u012bkr\u012bkos. Kosmosa nozar\u0113 to izmanto deta\u013c\u0101m, kas iztur karstumu, nedeform\u0113joties.<\/p>\n
Protams, tam ir d\u012bvain\u012bbas. Mitr\u0101s viet\u0101s tas laika gait\u0101 var l\u0113n\u0101m pasliktin\u0101ties - to sauc par degrad\u0101ciju zem\u0101 temperat\u016br\u0101 - t\u0101p\u0113c past\u0101v\u012bgi tiek veikti uzlabojumi, lai uzlabotu iztur\u012bbu. Lai samazin\u0101tu kait\u0113jumu videi, pieaug otrreiz\u0113j\u0101 p\u0101rstr\u0101de, un 3D druk\u0101\u0161ana paver iesp\u0113jas izmantot piel\u0101gotus bitus visda\u017e\u0101d\u0101kajos veidos, s\u0101kot ar medic\u012bniskiem implantiem un beidzot ar kosmosa apr\u012bkojumu.<\/p>\n
Kopum\u0101 cirkonija keramika ir tas klusais pan\u0101kumu guv\u0113js - eleganta, bet nesalau\u017eama, ar zemisk\u0101m sakn\u0113m un augsto tehnolo\u0123iju vibr\u0101cij\u0101m. M\u016bsu izmestaj\u0101 pasaul\u0113 ir atsvaidzino\u0161i, ja ir kaut kas, kas rad\u012bts, lai iztur\u0113tu. N\u0101kamreiz, kad redz\u0113siet nevainojamu gredzenu vai iztur\u012bgu implantu, ir iesp\u0113jams, ka cirkonija keramikas materi\u0101ls ir tas, kas to ir rad\u012bjis.<\/p>","protected":false},"excerpt":{"rendered":"
