Manaʻo ʻokoʻa
Alumina keramikahe ʻano mea ʻala me ka alumina (AI203) e like me ke kino nui.
Loaʻa nā seramika māmā ma o ka hoʻohana ʻana i nā mea ʻenehana ultra-fine ceramic maʻemaʻe kiʻekiʻe a me ka hoʻopau ʻana i nā pores e nā ʻano ʻenehana.
He ʻokoʻa ka hui ʻana a me ka hoʻokaʻawale ʻana
ʻO nā seramika aluminaua māhele ʻia i ke ʻano maʻemaʻe kiʻekiʻe a me ke ʻano maʻamau ʻelua.
ʻO nā seramika alumina maʻemaʻe kiʻekiʻe he mau mea seramika me AI203 ma luna o 99.9%.℃a me ka hoʻouna ʻana i ka nalu o 1 ~ 6um, hana ʻia i ke aniani hoʻoheheʻe e lawe i kahi hanauna o ka platinum crucible; E hoʻohana i kāna hoʻouna māmā a me ke kūpaʻa ʻana i ka corrosion metala alkali e like me ka ipu kukui sodium; Hiki ke hoʻohana ʻia e like me ka papa kaapuni i hoʻohui ʻia a me nā mea insulation kiʻekiʻe i ka ʻoihana uila.
He mea maʻamaualumina keramikaua māhele ʻia i 99 porcelain, 95 porcelain, 90 porcelain, 85 porcelain a me nā ʻano ʻē aʻe e like me ka ʻike o A1203, a i kekahi manawa ua helu pū ʻia ka ʻike A1203 ma ke ʻano he alumina ceramics maʻamau. Hoʻohana ʻia ka 99 alumina ceramic material no ka hana ʻana i ka crucible wela kiʻekiʻe, refractory furnace paipu a me nā mea pale lole kūikawā, e like me nā bearings seramika, nā sila seramika a me nā valve wai; Hoʻohana nui ʻia ʻo 95 alumina porcelain e like me ke kūpaʻa ʻana a me nā ʻāpana kūʻē; Hoʻohui pinepine ʻia ka porcelain 85 me ka talc e hoʻomaikaʻi i nā waiwai uila a me ka ikaika mechanical, a hiki ke hoʻopaʻa ʻia me ka molybdenum, niobium, tantalum a me nā metala ʻē aʻe, a hoʻohana ʻia kekahi e like me nā mea uila uila.
Hiki ke hoʻokaʻawale ʻia nā seramika māmā i ka alumini oxide transparent ceramics, yttrium oxide transparent ceramics, magnesium oxide transparent ceramics, yttrium aluminum garnet transparent ceramics, alumini magnesium acid transparent ceramics, transparent ferroelectric ceramics, aluminum nitride transparent ceramics, alumini nitride transparent ceramics, magnesium alumini spinel nā seramika māmā a pēlā aku.
Hana like ʻole
Alumina keramikawaiwai:
1. ʻO ka paʻakikī kiʻekiʻe i hoʻoholo ʻia e ka Shanghai Institute of Silicate o ka Chinese Academy of Sciences, ʻo HRA80-90 kona paʻakikī Rockwell, ʻo ka paʻakikī ka lua wale nō i ka daimana, ʻoi aku ka nui o ka pale ʻana o ke kila a me ke kila kila.
2. ʻO ke kūpaʻa maikaʻi maikaʻi loa i ana ʻia e ka Powder Metallurgy Institute o Central South University, ʻo kona kūpaʻa ʻaʻahu ua like ia me 266 mau manawa o ke kila manganese a me nā manawa 171.5 o ka hao chromium kiʻekiʻe. Wahi a kā mākou mea kūʻai aku ka nānā ʻana i nā makahiki ʻoi aku ma mua o ʻumi, ma lalo o nā kūlana hana like, hiki ke hoʻonui ʻia ke ola lawelawe o nā mea hana ma kahi o ʻumi mau manawa.
3. ʻO ke kaumaha māmā ʻO 3.5g / cm3 kona mānoanoa, he hapalua wale nō o ke kila, hiki ke hoʻemi nui i ka ukana o nā mea hana.
ʻO nā waiwai keramika māmā:
ʻO nā keramika māmā e like me ka lālā o nā ceramics kiʻekiʻe, ma kahi o ka hoʻoili ʻana i ka ceramic kiʻekiʻe wela kūpaʻa, corrosion resistance, kiʻekiʻe ikaika, kiʻekiʻe paʻakikī, kemika kūpaʻa, haʻahaʻa hoʻonui coefficient i ka hoʻohui, ʻo ka hoʻoili kukui kū hoʻokahi e hoʻonui i nā noi he nui.
Hoʻohana like ʻole
ʻO nā seramika aluminahoʻohana nui ʻia i nā mīkini, fiber optical, ʻoki ʻoki, lāʻau lapaʻau, meaʻai, kemika, aerospace a me nā ʻoihana ʻē aʻe.
Hoʻohana nui ʻia nā seramika māmā i nā kukui uila, nā mea laser, nā mea puka makani infrared, nā seramika flicker, nā mea electro-optical ceramics, nā mea pale.
