He aha nā hiʻohiʻona o ka alumina keramika?

ʻO nā seramika aluminaHe ʻano Al2O3 e like me ka mea maka nui, corundum (α-al2o3) ma ke ʻano he crystalline nui o ka mea seramika, i kēia manawa ka nui o ka nui o nā mea oxide ceramic o ka honua. A no ka meaalumina keramikaHe mea hoʻohana nui ia ma nā ʻano āpau o ke ola.

ʻO nā seramika aluminaloaʻa nā hiʻohiʻona hana penei:

1. E aahu i ka pale

Maʻemaʻe kiʻekiʻealumina keramikaloaʻa i ka pale lole maikaʻi loa, kūpono i nā ʻāpana i hoʻohana ʻia no ka manawa lōʻihi.

2, ʻaʻohe deformation

Maʻemaʻe kiʻekiʻealumina keramikaHe mau mea maikaʻi loa ia no nā ʻāpana kikoʻī no ka mea he ikaika ka piko a me ka ikaika compressive a ʻaʻole maʻalahi e hōʻino.

3, maʻalahi e hoʻomaʻemaʻe

Ka ili oalumina keramikaHe laumā, ʻaʻole maʻalahi ke pili i nā haumia, a maʻalahi hoʻi e hoʻomaʻemaʻe. No laila, kūpono ia no ka hoʻohana hou ʻana a me ka pono e mālama i ka maʻemaʻe ma ke kahua olakino.

4, pale kemika

ʻO nā seramika aluminaloaʻa i ka waika ikaika a me ke kūpaʻa alkali i ka corrosion kemika, a ʻaʻohe pono e hopohopo e pili ana i nā hopena kemika me nā lāʻau ʻē aʻe i ka wā e hoʻohana ai.

5, hoʻokuʻu maikaʻi

ʻO ka alumina ceramic maʻemaʻe kiʻekiʻe he mea hoʻoheheʻe maikaʻi loa ia ma muli o nā haumia haʻahaʻa, hiki iā ia ke pale i ka volta ma ke ʻano he insulating mea, haʻahaʻa haʻahaʻa haʻahaʻa, ʻoiai ma nā mahana kiʻekiʻe e mālama i ka insulation, a me ke kūpaʻa wela maikaʻi.

6, ka pale plasma

Ma muli o ka maʻemaʻe kiʻekiʻe o nā alumina ceramics (Al 2 O 3> 99.9%) a aneane ʻaʻohe intergranular segregation a, no laila, hoʻohana ʻia e like me kahi mea anti-plasma.

I ka hōʻuluʻulu ʻana, aia kekahi mau hiʻohiʻona hana o nā alumina seramika. He kūlana kiʻekiʻe ka alumina ceramics ma ke kahua o nā mea seramika, a hoʻohana nui ʻia i ka uila, nā mea uila, nā mīkini, nā textiles, aerospace a me nā māla ʻē aʻe.
