ʻEhiku mau hiʻohiʻona o ka Alumina Porcelain

1.High ikaika mechanical.Ka ikaika wili oalumina porcelain sintered productsa hiki i ka 250MPa, a ʻo nā huahana paʻi wela a hiki i 500MPa.ʻO ka maʻemaʻe o ka hui alumina, ʻoi aku ka kiʻekiʻe o ka ikaika.Hiki ke mālama i ka ikaika a hiki i 900 ° C ma nā wela kiʻekiʻe.Ke hoʻohana nei i ka ikaika mechanical oalumina porcelain, hiki ke hana i nā ʻāpana mechanical e like me ka porcelain.Ka mohs paakiki oalumina keramikahiki ke hiki i ka 9, me ka maikaʻi o kona pale ʻana, no laila ua hoʻohana nui ʻia ia i ka hana ʻana i nā mea hana, nā kīwī pōpō, nā huila wili, nā kui seramika, nā bearings, a me nā mea ʻē aʻe, i waena o nā mea hana alumina ceramic a me nā kiwi ʻoihana i hoʻohana nui ʻia.

2.High resistivity, maikaʻi uila insulation hana.Ka lumi wela resistivity oalumina porcelainʻo 1015 Ω·cm, a ʻo ka ikaika insulation he 15kV/mm.Ke hoʻohana nei i kona insulation a me kona ikaika, hiki ke hana ʻia i substrate, socket, spark plug, circuit shell a pēlā aku.

3.High paakiki.ʻAlumina porcelainmohs paʻakikī o 9, a me ke kūpaʻa maikaʻi loa, no laila ua hoʻohana nui ʻia i ka hana ʻana i nā mea hana, nā huila wili, nā mea wili, kiʻi make, extrusion die, bearings a pēlā aku.Hiki ke hoʻokō ʻia ka pololei kiʻekiʻe i ka wikiwiki o ka ʻoki ʻana i ka wā e hoʻohana ana i ka mīkini kaʻa a me nā ʻāpana mokulele e hoʻohana ana i nā mea hana alumina ceramic.

4.High hehee nui.ʻO 2050 ℃ ka pale ʻana o ka corrosion o ka alumina porcelain, a maikaʻi ke kūʻē iā Be, Sr, Ni, Al, V, Ta, Mn, Fe, Co a me nā metala hoʻoheheʻe ʻē aʻe.He kūpaʻa loa ia i ka erosion NaOH, ke aniani a me ka slag.ʻAʻole ia e launa pū me Si, P, Sb a me Bi i ka lewa inert.No laila, hiki ke hoʻohana ʻia e like me ka refractory material, umu pahu, aniani uea kaha kiʻi crucible, hollow ball, fiber, thermocouple protective cover, etc.

5. Paʻa kemika maikaʻi loa.He nui nā sulfides paʻakikī, phosphates, arsenides, chlorides, nitride, bromides, iodide, oxides, a me ka sulfuric, hydrochloric, nitric, a me nā waikawa hydrofluoric ʻaʻole pili me ka alumina.No laila, hiki ke hana ʻia ka alumina i mea metala maʻemaʻe a me hoʻokahi crucible ulu kristal, nā hui kanaka, nā iwi hana a pēlā aku.

6. ʻO nā hiʻohiʻona Optical.ʻAlumina porcelainhiki ke hana ʻia i mea ʻike (transparent alumina porcelain), ke kukui sodium vapor, microwave fairing, infrared window, laser oscillation element, etc.

7.Lonic conductivity.ʻAlumina porcelainhiki ke hoʻohana ʻia ma ke ʻano he mea lā a me nā mea pākaukau.
