Hoʻohana ʻia ʻo Aluminum nitride ceramic no nā ʻāpana wela a me nā ʻāpana kū i ka corrosion
Nā Pōmaikaʻi o Aluminum Nitride Ceramics
1. Kiʻekiʻe thermal conductivity
Aluminum nitride ceramics i kiʻekiʻe thermal conductivity, a me ko lakou thermal conductivity mea e like me ka kiʻekiʻe e like me 220 ~ 240W/m·K, ʻo ia ka 2 ~ 3 manawa o ka silicate ceramics. Hiki i kēia conductivity thermal kiʻekiʻe ke hoʻoponopono maikaʻi i ka pilikia o ka hoʻohemo ʻana o ka wela o nā mea uila, no laila ua hoʻohana nui ʻia i ka ʻoihana uila.
2. Ka hoʻokuʻu kiʻekiʻe
ʻO ka alumini nitride ceramic kahi mea insulating maikaʻi loa me ka resistivity kiʻekiʻe a me ka dielectric mau. 'O ia ho'i, hiki iā ia ke ho'oka'awale maika'i i nā mea kaapuni a pale i nā pōkole kaapuni a me ka wela.
3. Kiʻekiʻe corrosion kū'ē
ʻO ka alumini nitride ceramics he maikaʻi ka corrosion resistance i ka hapa nui o nā waikawa, nā kumu a me nā mea hoʻoheheʻe organik. He koho maikaʻi kēia i ka ʻoihana kemika a me ka lāʻau lapaʻau.
4. Ka ikaika mechanical kiʻekiʻe
Aluminum nitride ceramics i kiʻekiʻe mechanical ikaika, a me ko lakou kulou ikaika a me ka haʻi paʻakikī he 800MPa a me 10-12mpa · m1/2, pakahi. ʻO kēia ikaika kiʻekiʻe a me ka paʻakikī kiʻekiʻe e hoʻohana nui ʻia i ka ʻoki ʻana i nā mea hana, nā ʻāpana ʻāpana pale lole.
Noi o Aluminum Nitride Ceramics
1. ʻOihana uila
I ka ʻoihana uila, hoʻohana nui ʻia nā seramika nitride alumini e hana i ka mana kiʻekiʻe a me nā mea uila uila kiʻekiʻe. Ma muli o kāna conductivity thermal kiʻekiʻe a me ka hana insulation maikaʻi loa, hoʻoponopono maikaʻi ia i ka pilikia o ka hoʻohemo ʻana o ka wela o nā mea uila, a hōʻoiaʻiʻo hoʻi i ka hilinaʻi kiʻekiʻe o nā lako uila. Eia kekahi, hiki ke hoʻohana ʻia nā seramika nitride alumini no ka hana ʻana i nā mīkini microwave a me nā mea hawewe millimeter, e hoʻomaikaʻi i ka hana a me ke kūpaʻa o nā mea kamaʻilio.
2. ʻOihana kaʻa
I ka ʻoihana kaʻa, hoʻohana nui ʻia nā seramika nitride alumini no ka hana ʻana i nā ʻāpana mīkini, cylinder liners a me nā pad brake. Ma muli o ke kūpaʻa kiʻekiʻe o ka corrosion a me ka ikaika mechanical kiʻekiʻe, hiki iā ia ke mālama i ka hana maikaʻi i nā mahana kiʻekiʻe a me nā wahi paʻakikī no ka manawa lōʻihi. Eia kekahi, hiki ke hoʻohana ʻia nā seramika nitride alumini no ka hana ʻana i nā mea ʻike kinoea e ʻike i nā mea ʻino i loko o ka pauku kaʻa a hāʻawi i kumu no ka loiloi ʻenehana.
3. Kahua Optical
Ma ke kahua o ka optics, alumini nitride ceramics loaʻa ka thermal conductivity kiʻekiʻe a me ke kūpaʻa wela maikaʻi loa, no laila ua hoʻohana nui ʻia lākou i ka hana ʻana i nā lasers hana kiʻekiʻe, nā kiʻi ʻoniʻoni a me nā fiber optical a me nā mea ʻē aʻe. Eia kekahi, hiki ke hoʻohana ʻia nā seramika nitride alumini no ka hana ʻana i nā mea pono e like me nā spectrometers, nā mea ʻike wela kiʻekiʻe a me nā mea ʻike infrared, e hoʻomaikaʻi i ka pololei a me ka hilinaʻi o nā ana optical.
4. kahua Semiconductor
Hoʻohana ka pā wela ma nā mea semiconductor i nā hiʻohiʻona o ka conductivity thermal kiʻekiʻe, ka waikawa a me ke kūpaʻa alkali a me ka pale ʻana o ka alumini nitride ceramics. Eia nō naʻe, ʻo ka alumini nitride heat plate aia nō i ka noiʻi a me ka hoʻomohala ʻana ma Kina, akā he ʻāpana koʻikoʻi ia i ka hana chip.
