ʻO ka paipu seramika kūpaʻa Zirconia
ʻO ka waiwai zirconium i hōʻoia ʻia o ka honua ma kahi o 19 miliona tons, a ʻo ka zirconia ka mea maʻamau i hana ʻia mai ka zirconium ore hoʻomaʻemaʻe. Aia ʻekolu mau kristal o ZrO2 maʻemaʻe ma ke kaomi lewa: monoclinic (Monoclinic) zirconia (m-ZrO2), tetragonal zirconia (t-ZrO2) a me cubic (Cubic) zirconia (c-ZrO2). Aia nā ʻano aniani ʻekolu ma luna i nā pae wela like ʻole a hiki ke hoʻololi ʻia kekahi i kekahi.
ʻO nā koi o ka hana ʻana o Zirconia ceramic no ka maʻemaʻe kiʻekiʻe, ka hana hoʻopuehu maikaʻi, ka ʻāpana ultrafine, ka hāʻawi ʻana i ka nui o ka pauka, ke ʻano o ka hoʻomākaukau ʻana o nā mea he nui, ʻo ka hoʻomaʻemaʻe zirconia ka nui o ka chlorination a me ka thermal decomposition, alkali metal oxidation decomposition, lime melting method, plasma arc method, precipitation method, colloid method, hydrolysis method, spray ʻO ke ʻano pyrolysis, a me nā mea ʻē aʻe. ʻO ke ʻano o ka hana pauda he ʻano coprecipitation, sol{1}}gel method, evaporation method, supercritical synthesis method, microemulsion method, hydrothermal synthesis method a me vapor deposition method.
Ma nā ʻōlelo o nā seramika hoʻolālā, hoʻohana nui ʻia ka zirconia ceramics ma ke kahua o nā seramika kūkulu ʻia ma muli o ko lākou mau pono o ka paʻakikī kiʻekiʻe, ka ikaika kuʻekuʻe kiʻekiʻe a me ke kūpaʻa lole kiʻekiʻe, ka hana insulation wela maikaʻi loa a me ka coefficient hoʻonui wela kokoke i ke kila. Aia ka mea nui: Y-TZP wili poepoe, dispersion and grinding medium, nozzle, ball valve seat, zirconia mold, micro fan shaft, optical fiber pine, fiber sleeve, drawing forl and cutting tools, wear-tools resistance, pihi lole, case and watch band, bracelet and pendant, ball bearing, golf ball light ball bat a me kekahi lumi wela. ʻaʻahu -mau mea kūʻē, etc.
Ma nā ʻōlelo o nā seramika hana, hoʻohana ʻia kona kūpaʻa kiʻekiʻe kiʻekiʻe e like me ka induction heat tube, refractory material a me ka mea wela. Loaʻa i nā seramika Zirconia nā ʻāpana hana uila koʻikoʻi, hoʻohana nui ʻia i ka sensor oxygen, solid oxide fuel cell (Solid Oxide Fuel Cell, SOFC) a me ke kino wela wela. ZrO2 He kiʻekiʻe refractive index (N-21 ^ 22), i loko o ka ultra-fine zirconia pauda i hoʻohui ʻia kekahi mau mea kala (V2O5, MoO3, Fe2O3, etc.), hiki ke hana ʻia i loko o nā mea translucent polycrystalline ZrO2 kala, e like me nā pōhaku maoli e ʻā ana me nā kukui kala, hiki ke hana ʻia i nā ʻano mea hoʻonaninani. Eia kekahi, hoʻohana nui ʻia ka zirconia i ka uhi ʻana i ka thermal barrier coating, catalyst carrier, mālama olakino, mālama olakino, refractory material, textile a me nā māla ʻē aʻe.
Nā huahana pale: zirconia resistant ceramic tube, China zirconia resistant ceramic tube mea hana, mea hoʻolako, hale hana
