Iztur\u012bba pret augst\u0101m temperat\u016br\u0101m<\/h2>\n

melnais dimanta cirkonijs, neraugoties uz t\u0101 tum\u0161o izskatu, ir neticami iztur\u012bgs keramikas materi\u0101ls, kas sp\u0113j iztur\u0113t augst\u0101ku temperat\u016bru nek\u0101 liel\u0101k\u0101 da\u013ca citu materi\u0101lu.

Keramika ir ne tikai izcila iztur\u012bba pret nodilumu un siltuma absorbciju, nemainot t\u0101s virsmu, bet t\u0101 ir ar\u012b \u013coti iztur\u012bga pret nodilumu un karstuma ietekm\u0113 nemaina formu un neiztvaikst - ide\u0101li piem\u0113rota lietojumiem, kas var\u0113tu saboj\u0101t citu keramiku.<\/p>\n

melnais dimanta cirkonijs ir ne tikai termiski \u013coti stabils, bet ar\u012b iztur \u0137\u012bmisko oksid\u0101ciju un koroziju, jo t\u0101 zem\u0101 caurlaid\u012bba ne\u013cauj sk\u0101beklim mijiedarboties ar t\u0101 virsmu, kas ir \u013coti svar\u012bgi, lai izvair\u012btos no plais\u0101\u0161anas vai deform\u0101cijas izstr\u0101d\u0101jumos, kas izgatavoti no \u0161\u012b materi\u0101la.<\/p>\n

Augsta iztur\u012bba pret koroziju<\/h2>\n

Cirkonija oks\u012bds ir \u0101rk\u0101rt\u012bgi iztur\u012bgs materi\u0101ls ar lielisku \u0137\u012bmisko inertumu, kas to padara \u013coti iztur\u012bgu pret koroziju.
