ʻO ka pauka Zirconia he mau ʻano o ka paʻakikī kiʻekiʻe, ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa i ka pala kemika, ke kūpaʻa ʻaʻahu, ka conductivity wela liʻiliʻi, ke kūpaʻa haʻalulu wela ikaika, ke kūpaʻa kemika maikaʻi, nā mea hui maikaʻi loa, a pēlā aku. Hiki ke hoʻomaikaʻi ʻia nā waiwai o ka mea ma ka hoʻohui ʻana i ka nanometer zirconia me ka alumina a me ka silicon oxide. ʻAʻole hoʻohana wale ʻia ka Nano zirconia i nā keramika kūkulu a me nā keramika hana. Hoʻohui ʻia ka Nano zirconia me nā ʻano conductive like ʻole, hoʻohana ʻia i ka hana ʻana o nā electrode pākahiko paʻa.

Nā Pōmaikaʻi o ka Pauka Zircon

» Loaʻa i ka huahana ka hana sintering maikaʻi, maʻalahi ka sintering, ka lakio shrinkage paʻa a me ke kūlike shrinkage sintering maikaʻi;

» He maikaʻi loa nā waiwai mechanical o ke kino sintered, ikaika kiʻekiʻe, paʻakikī a me ka paʻakikī;

»He maikaʻi kona kahe ʻana, kūpono no ke kaomi maloʻo, ke kaomi isostatic, ka paʻi 3D a me nā kaʻina hana hoʻoheheʻe ʻē aʻe.

Nā noi pauka Zirconia

Hāʻawi mākou i ka pauka zirconia maʻemaʻe kiʻekiʻe, hiki ke hoʻohana ʻia i nā manawa he nui, e like me ka mea cathode o ka pākahi lithium, ka ʻano TZP, nā niho, ka backplate o ke kelepona paʻalima, ka zirconia gem, i waena o lākou:

Hoʻohana ʻia ma ke ʻano he mea maikaʻi:

ʻO ka pauka zirconia i hāʻawi ʻia e mākou he mau ʻano o ka nui maikaʻi, ka hoʻolaha like ʻana o ka nui o nā ʻāpana, ʻaʻohe agglomeration paʻakikī, a me ka sphericity maikaʻi. ʻO ka hoʻopili ʻana i loko o ka mea cathode o ka pākahi lithium hiki ke hoʻomaikaʻi i ka hana pōʻaiapuni o ka pākahi a me ka hana wikiwiki. Ma ka hoʻohana ʻana i kona conductivity, hiki ke hoʻohana ʻia ka pauka zirconia maʻemaʻe kiʻekiʻe no ka hana electrode i loko o ka pākahi paʻa hana kiʻekiʻe. Hiki ke hoʻohana ʻia ka pauka Zirconia (99.99%) ma ke ʻano he mau mea anode no nā pākahi lithium, e like me ka nickel cobalt lithium manganate (NiCoMn) O2), lithium cobaltite (LiCoO2), lithium manganate (LiMn2O4).

No nā lālā kūkulu:

ʻO TZP, nā keramika polycrystalline tetragonal zirconia. Ke kāohi ʻia ka nui o ka mea hoʻopaʻa i kahi nui kūpono, hiki ke mālama ʻia ʻo t-ZrO2 i kahi kūlana metastable i ka mahana o ka lumi. Ma lalo o ka hana o ka ikaika o waho, hiki iā ia ke hana i ka hoʻololi ʻana o ka pae t-ZrO2, hoʻoikaika i ke kino ZrO2 hoʻololi ʻole, a hoʻomaikaʻi i ka laina haki o ka keramika holoʻokoʻa. Loaʻa iā TZP nā waiwai mechanical maikaʻi loa e like me ka ikaika kiʻekiʻe, ka paʻakikī kiʻekiʻe, a me ke kūpaʻa kiʻekiʻe o ka ʻaʻahu. Hiki ke hoʻohana ʻia e hana i nā ʻāpana kūkulu pale ahi a me nā ʻāpana kūkulu pale wela kiʻekiʻe.

No nā niho porcelain:

He ikaika kiʻekiʻe ko Zirconia, biocompatibility maikaʻi, ʻaʻohe hoʻoulu ʻana i ka gingiva, a ʻaʻohe hopena maʻi, no laila kūpono loa ia no ka hoʻohana waha. No laila, hoʻohana pinepine ʻia ka pauka zirconia e hana i nā niho keramika zirconia. Hana ʻia nā niho keramika āpau Zirconia e ka hoʻolālā kōkua kamepiula, ka nānā ʻana o ka laser, a laila hoʻomalu ʻia e kahi polokalamu kamepiula. Loaʻa iā ia nā ʻano o ke ʻano translucent maikaʻi, ka nui o ka density, a me ka ikaika, ka lihi kokoke kūpono, ʻaʻohe gingivitis, ʻaʻohe keʻakeʻa i ka X-ray, a pēlā aku. Hiki iā ia ke loaʻa nā hopena hoʻoponopono lōʻihi i ka lāʻau lapaʻau.

Hoʻohana ʻia e hana i ka ʻaoʻao hope o ke kelepona paʻalima:

I ke au 5G, pono ka wikiwiki o ka hoʻoili ʻana i nā hōʻailona he 1-100 mau manawa o 4G. Hoʻohana ka kamaʻilio 5G i kahi spectrum ma mua o 3GHz, a ʻoi aku ka pōkole o kona nalu millimeter-wave. Ke hoʻohālikelike ʻia me ka backplane metala, ʻaʻohe mea hoʻopilikia o ka backplane keramika o ke kelepona paʻalima i ka hōʻailona a he hana maikaʻi loa ia o nā mea ʻē aʻe. Ma waena o nā mea keramika āpau, loaʻa i ka keramika zirconia nā pono o ka ikaika kiʻekiʻe, ka paʻakikī kiʻekiʻe, ke kū'ē ʻana i ka waikawa a me ka alkali, ke kū'ē ʻana i ka pala, a me ke kūpaʻa kemika kiʻekiʻe. I ka manawa like, loaʻa iā ia nā ʻano o ke kū'ē ʻana i ke kahakaha, ʻaʻohe pale hōʻailona, hana hoʻopuehu wela maikaʻi loa, a me ka hopena maikaʻi. No laila, ua lilo ka zirconia i ʻano hou o ke kino kelepona paʻalima ma hope o ka plastic, metal, a me ke aniani. I kēia manawa, ʻo ka hoʻohana ʻana o ka keramika zirconia i nā kelepona paʻalima ua hana nui ʻia me kahi backplate a me kahi uhi ʻike manamana lima.

Hoʻohana ʻia no ka hana ʻana i nā pōhaku zirconia:

ʻO ka hana ʻana o nā pōhaku makamae zirconia mai ka pauka zirconia he kahua koʻikoʻi ia o ka hana hohonu a me ka hoʻohana ʻana o ka zirconia. He kristal paʻakikī, ʻaʻohe kala, a he kristal kīnā ʻole ka cubic zirconia synthetic. Ma muli o kona kumukūʻai haʻahaʻa, paʻa, a like ke ʻano me nā daimana, ʻo nā pōhaku makamae cubic zirconia nā mea pani nui loa no nā daimana mai ka makahiki 1976.
