ʻO nā ʻāpana keramika alumina kahi ʻano mea keramika i hana nui ʻia me ka alumina maʻemaʻe kiʻekiʻe (Al ₂ O3), nona ka paʻakikī kiʻekiʻe loa, ke kūpaʻa ʻana i ka ʻaʻahu, ke kūpaʻa wela kiʻekiʻe, a me ke kūpaʻa kemika. Hoʻohana nui ʻia ia ma nā ʻano ʻoihana he nui a ʻo ia ka mea keramika ʻoihana nui loa a hoʻohana nui ʻia ma ke ʻano o ka nui o ka hana.

Pōmaikaʻi

1. Paʻakikī kiʻekiʻe a me ke kūpaʻa ʻana i ka ʻaʻahu

ʻOi aku ka paʻakikī o Mohs o nā keramika alumina ma ka pae 9, ʻo ka lua wale nō ma hope o ke daimana. Ke kūpaʻa ʻana i ka ʻaʻahu: ʻO kona kūpaʻa ʻana i ka ʻaʻahu he 266 mau manawa o ke kila manganese a me 171.5 mau manawa o ka hao i hoʻolei ʻia me ka chromium kiʻekiʻe.

2. Ke kūpaʻa wela kiʻekiʻe a me ke kūpaʻa wela

Ke kūpaʻa wela kiʻekiʻe: ʻO ke kiko heheʻe o nā keramika alumina he kiʻekiʻe ia e like me 2050 ℃, a hiki iā ia ke mālama i ka hana paʻa ma kahi mahana kiʻekiʻe o 2000 ℃. Paʻa wela: He haʻahaʻa kona coefficient o ka hoʻonui wela a hiki ke mālama i ke kūpaʻa kūkulu ma lalo o nā loli wela koʻikoʻi.

3. Hoʻolālā māmā Ka nui:

ʻO ka nui o nā keramika alumina he 3.6-3.8g/cm³ wale nō, ʻoi aku ka māmā ma mua o 50% ma mua o ke kila. No ka laʻana, ʻo ka hoʻohana ʻana i nā ʻāpana keramika alumina i loko o nā mokulele hiki ke hōʻemi i ke kaumaha ma 30% a hoʻomaikaʻi nui i ka pono o ka wahie.

4Ke kūpaʻa ʻana i ka palaho a me nā waiwai insulation Ke kūpaʻa ʻana i ka palaho:

Ke kūpaʻa maikaʻi loa i nā waikawa ikaika, alkalis, a me nā mea paʻakai, kūpono no nā mea hana kemika, nā kiwikā anti-corrosion, a pēlā aku. Hoʻopaʻa ʻana: Me ka resistivity o ≥ 1 × 10 ¹⁴Ω· cm, ʻo ia ka mea makemake ʻia no nā substrates hāmeʻa uila alapine kiʻekiʻe.

5. Ka waiwai kūpono kiʻekiʻe Ka waiwai kūpono:

ʻO kona ola lōʻihi a me nā ʻano mālama haʻahaʻa e hoʻemi nui ana i nā kumukūʻai lōʻihi.

6. Hana ʻana i hoʻopilikino ʻia Machining pololei:

Ma o nā kaʻina hana e like me ke kaomi maloʻo, ka hoʻoheheʻe ʻana i ka injection, a me ka paʻi 3D, hiki ke hana ʻia nā ʻāpana kikoʻī paʻakikī e hoʻokō i nā pono o nā kahua kiʻekiʻe e like me nā semiconductors a me nā lako lapaʻau. Hoʻopilikino pane wikiwiki: Hiki i nā ʻoihana ke hoʻopilikino i nā ʻāpana seramika e like me nā palena o nā lako, e hōʻemi ana i nā kumukūʻai hoʻololi.

7. Ka Palekana Kaiapuni a me ke Kūpaʻa Hana haʻahaʻa kalapona:

Loaʻa nā mea maka no nā keramika alumina (pauka alumina) i nā wahi ākea, a ʻoi aku ka haʻahaʻa o ka hoʻohana ʻana i ka ikehu o ke kaʻina hana sintering ma mua o ka hoʻoheheʻe ʻana i ka metala. Hana hou: Hiki ke kuʻi ʻia nā keramika ʻōpala a hana hou ʻia ma ke ʻano he mea maka e pale aku i nā pilikia haumia i hoʻokumu ʻia e ka ʻōpala mea metala.
