MgAl2O4 ka lepo
wehewehe
Hoʻohana nui ʻia nā kristal hoʻokahi o Magnesium aluminate (MgAl2O4) i nā mea sonic a me microwave a me nā substrates epitaxial MgAl2O4 o nā mea III-V nitride.He mea paʻakikī ka ulu ʻana o ka kristal MgAl2O4 ma mua no ka mea paʻakikī ke mālama ʻana i kāna ʻano aniani hoʻokahi.Akā i kēia manawa ua hiki iā mākou ke hāʻawi i nā kristal MgAl2O4 kiʻekiʻe kiʻekiʻe.

ʻO ka wehewehe ʻana o ka substrate MgAl2O4
ʻO ka pāpaʻi MgAl2O4 e pili ana i kahi ʻano pāpaʻi kūikawā i hana ʻia me ka magnesium aluminate (MgAl2O4).He mea seramika ia me nā waiwai i makemake ʻia no nā noi like ʻole.
ʻO MgAl2O4, ʻike ʻia hoʻi ʻo spinel, he mea paʻa paʻakikī me ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa kemika a me ka ikaika mechanical.Kūpono kēia mau waiwai no ka hoʻohana ʻana ma ke ʻano he substrate i nā ʻano ʻoihana like ʻole, me ka uila, optics a me ka aerospace.
Ma ke kahua o ka uila, hiki ke hoʻohana ʻia nā substrates MgAl2O4 ma ke ʻano he kahua no ka ulu ʻana i nā kiʻi ʻoniʻoni lahilahi a me nā papa epitaxial o semiconductors a i ʻole nā mea uila ʻē aʻe.Hiki i kēia ke hana i nā mea uila e like me transistors, integrated circuit a me nā sensor.
I loko o nā optics, hiki ke hoʻohana ʻia nā substrates MgAl2O4 no ka waiho ʻana i nā ʻili kiʻi ʻoniʻoni ʻoniʻoni e hoʻomaikaʻi i ka hana a me ka lōʻihi o nā mea optical e like me nā lens, nā kānana a me nā aniani.ʻO ka ʻike o ka substrate ma waena o kahi ākea o nā lōʻihi nalu e kūpono loa ia no nā noi ma nā ʻāpana ultraviolet (UV), ʻike ʻia, a kokoke i ka infrared (NIR).
Ma ka ʻoihana aerospace, hoʻohana ʻia nā substrates MgAl2O4 no kā lākou conductivity thermal kiʻekiʻe a me ke kūpaʻa haʻalulu wela.Hoʻohana ʻia lākou e like me nā poloka kūkulu hale no nā ʻāpana uila, nā ʻōnaehana pale wela a me nā mea hana.
ʻO ka holoʻokoʻa, loaʻa i nā substrates MgAl2O4 ka hui pū ʻana o nā waiwai optical, thermal, a me nā mīkini e hoʻohana pono ai i nā ʻano noi like ʻole, me nā mea uila, optics, a me nā ʻoihana aerospace.
