Hoʻomaka i ka nitride aluminika

ʻO ka nitride aluminika (AlN) he pūhui nonmetallic keʻokeʻo a hina paha me ke kaumaha molekala o 40.98, kahi heheʻe o 2200 ℃, kahi paila o 2510 ℃, a me kahi mānoanoa o 3.26g/cm³.ʻO ka nitride alumini he mea hana seramika hou me ka conductivity thermal kiʻekiʻe, ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa corrosion kiʻekiʻe, ka insulation kiʻekiʻe a me ke kūpaʻa creep maikaʻi loa, i hoʻohana nui ʻia i ka uila, ka uila uila, ka aerospace, nā mea pono a me nā māla ʻē aʻe.

Nā waiwai o ka nitride aluminika

1. Thermal waiwai:ʻO ka nitride aluminika he kiʻekiʻe ka wela wela, ʻelua wale nō i ke daimana, a hiki ke hoʻohana ʻia no ka manawa lōʻihi i nā wela kiʻekiʻe.

2. Nā waiwai mīkini:ʻO ka alumini nitride he paʻakikī kiʻekiʻe a me ke kūpaʻa maikaʻi.

3. Nā waiwai uila: ʻO ka nitride aluminika he mea hoʻolale uila maikaʻi loa.

4. Nā waiwai Optical:Loaʻa i ka nitride alumini nā waiwai optical maikaʻi loa, a ʻo kona ʻano uila māmā he 200-2000nm, me kahi transmittance o ka 95%.

ʻO ke ʻano o ka hoʻomākaukau ʻana o ka nitride aluminika

ʻO ke ʻano o ka hoʻomākaukau ʻana o ka nitride alumini ka mea nui:

1. Keʻano ho'ēmi karbothermal:Ua hui pū ʻia ka calcium carbonate a me ka alumina me ka pauka kalapona, hoʻomehana ʻia i 1500-1600 ℃ i loko o ka umu ahi, no laila e hana ke kalapona me ka oxygen e hana i ke kalapona kalapona, ke kalapona i koe me ka calcium carbonate e hana i ka calcium a me ka carbon dioxide, a loaʻa ka alumini. nitride.

2. Ke ala nitriding pololei:E hoʻohui i ka alumina a i ʻole ka paʻakai alumini me ka ammonia, e hoʻohui i ka nui o ka ammonium chloride e hoʻoponopono ai i ka waiwai pH, e kiʻi i kahi paʻakikī o ka alumini ion a me ka ammonia ion, a laila wela i ka wela kiʻekiʻe a hiki i 1000-1200 ℃, i hiki ai i ka amonia decomposition i loko o ke kinoea amonia. , a loaʻa ka nitride aluminika.

3. Sputtering ala:me ka ikehu kiʻekiʻe ion beam sputtering aluminika tetrachloride a me ka nitrogen, alumini tetrachloride pane me ka nitrogen e hana i ka alumini nitride ma ke ana wela, oiai e ohi ana i ka alumini nitride pauda.

ʻO ka hoʻohana ʻana i ka alumini nitride

1. kahua uila:ʻO ka nitride aluminika, ma ke ʻano he mea hoʻonaninani wela kiʻekiʻe, hoʻohana nui ʻia i ka hoʻopili ʻana o nā mea uila, e like me nā semiconductor chips, transistors, etc.

2. kahua mana:ʻO ke kūpaʻa wela kiʻekiʻe a me ka corrosion resistance o ka alumini nitride e hoʻohana nui ʻia i nā ʻōnaehana mana, e like me nā transformers, capacitors a pēlā aku.

3. kahua mokulele:ʻO ka ikaika kiʻekiʻe o ka alumini nitride, ka paʻakikī kiʻekiʻe a me ke kūpaʻa creep maikaʻi loa e hoʻohana nui ʻia i ke kahua aerospace, e like me nā ʻenekini mokulele, nā satellite a pēlā aku.

4. kahua mea kani pololei:ʻO ka transmittance māmā kiʻekiʻe a me nā waiwai optical maikaʻi loa o ka alumini nitride e hoʻohana nui ʻia i ke kahua o nā mea pono, e like me nā lens optical, prisms, etc.

Ka manaʻolana hoʻomohala o ka nitride aluminika

Me ka hoʻomau mau ʻana o ka ʻepekema a me ka ʻenehana, alumini nitride ma ke ʻano he ʻano mea seramika hou, hoʻomau ka hoʻonui ʻana o kāna kahua noi, ke piʻi nei ka noi mākeke.I ka wā e hiki mai ana, me ka hoʻomau mau ʻana o ke kaʻina hana hoʻomākaukau nitride aluminika a me ka hoʻemi ʻana o ke kumukūʻai, e hoʻohana ʻia ka nitride aluminika i nā kula hou aku.
