ʻO ka nano magnesium oxide kahi mea maʻamau alkaline oxide.Ma muli o kona wahi hoʻoheheʻe kiʻekiʻe o 2800 ° C a me kekahi mau waiwai kūikawā a maikaʻi loa, hiki ke hoʻohana ʻia i ka māla ceramic kiʻekiʻe.Ma ke ʻano o ka noi, hiki ke hoʻokaʻawale ʻia i ʻelua mau ala: ka hoʻopili pololei ʻana i nā seramika a hoʻohana ʻia ma ke ʻano he kōkua sintering no nā seramika ʻē aʻe.
Hoʻopili pololei i nā seramika
ʻO ka nano magnesium oxide kahi mea waiwai maikaʻi loa.Ma muli o kona kūpaʻa wela maikaʻi a me ke kūpaʻa ikaika i ka erosion e nā metala alkaline solutions, kūpono pinepine nā seramika magnesium oxide no nā wahi wela kiʻekiʻe.Hiki ke hoʻohana ʻia e like me ka crucible no ka hoʻoheheʻe ʻana i nā metala, a ma ka ʻoihana ikehu atomic he kūpono no ka hoʻoheheʻe ʻana i ka uranium a me ka thorium.Hiki ke hoʻohana ʻia e like me ka lima pale no nā thermocouple.No ka mea, loaʻa iā ia ka waiwai o ka ʻae ʻana i nā hawewe electromagnetic e hele i loko, hiki ke hoʻohana ʻia ma ke ʻano he uhi radar a me nā mea puka makani projection no ka radiation infrared.He mea maka no ka piezoelectric a me nā mea superconducting, a he mea pili i ke kaiapuni a kū i ka corrosion.Hiki ke hoʻohana ʻia ma ke ʻano he mea lawe sintering seramika, ʻoi aku hoʻi no ka pale sintering o nā huahana seramika e like me β-Al2O3 i loaʻa nā mea corrosive a me nā mea maʻalahi i nā wela kiʻekiʻe.
Hoʻohana ʻia e like me ke kōkua sintering no nā seramika ʻē aʻe
Hiki ke hoʻohui pū ʻia ka Nano magnesium oxide i ka hoʻomākaukau ʻana o nā ceramics ʻē aʻe, kahi hopena maikaʻi i ka hoʻohaʻahaʻa ʻana i ka mahana hoʻololi aniani, hoʻohaʻahaʻa i ka mahana sintering, a me ka hoʻomaikaʻi ʻana i nā ʻano optical a me nā mechanical o nā seramika, a laila e kōkua iā mākou e loaʻa nā mea seramika kiʻekiʻe. .
No ka laʻana, ua lilo ka silicon nitride ceramics i kekahi o nā mea hoʻolālā kiʻekiʻe kiʻekiʻe ma muli o ko lākou ikaika kiʻekiʻe kiʻekiʻe, ke kūpaʻa haʻalulu wela, a me ke kūpaʻa kemika.Eia nō naʻe, ʻo kona paʻa covalent ikaika a me ka coefficient diffusion haʻahaʻa e paʻakikī i ka hoʻopaʻa ʻana i ka sinter.Hiki i ka hoʻohui o ka magnesium oxide ke hana me ka silica ma ka ʻili o ka pauka nitride silicon i ka wā o ka sintering e hana i ka pae wai silicate, hiki ke hoʻoikaika maikaʻi i ka sintering o ka silicon nitride ceramics.I kēia manawa, hoʻohana mau ʻia nā mea kōkua sintering composite MgO-Y2O3 no ka hoʻokō ʻana i ke kaomi ʻana o ka lewa o nā seramika nitride silika.
I ka hōʻuluʻulu manaʻo, he hana koʻikoʻi ka nano magnesium oxide i ka māla seramika.Hiki iā ia ke hana ma ke ʻano he kumu kumu a mea hoʻohui paha e hoʻomaikaʻi ai i ka hana a me ka hana o nā seramika, a laila e hoʻolaha i ka holomua a me ka hoʻomohala ʻana o ka ʻoihana keramika.
