ʻO kāna hale noho insulation uila e hōʻoia i ka hoʻomaikaʻi ʻana i ka wela ʻaʻole e hoʻopilikia i ka palekana dielectric, hana ia i mea kūpono no nā kaapuni kiʻekiʻe a me nā alapine kiʻekiʻe.
3.2 Hoʻopuka Hoʻohui a me ka Hoʻoponopono Ceramic
I ka hana hoʻohui, ʻoi aku ka maikaʻi ma ka hoʻopaʻa ʻana i ka binder a me ka sintering laser me ka akahele (SLS), He mea koʻikoʻi nā pauka AlN spherical no ka loaʻa ʻana o ka nui o ka moena pauda mau a me ka pālahalaha ʻana o ka papa maʻamau.
ʻO kā lākou flowability e hōʻoia i ka waiho ʻana o ka papa kīnā ʻole, ʻoiai ʻo ka mānoanoa o ka puʻupuʻu kiʻekiʻe e hoʻonui ai i ke kūpaʻa pili i ke kaiapuni a hoʻohaʻahaʻa i ka emi ʻana i ka wā sintering.
Hiki i nā pauka poepoe ke hana i nā ʻāpana seramika paʻakikī me nā hiʻohiʻona maikaʻi a me ka pololei ʻokoʻa., kōkua i ka aerospace, palekana, a me nā mea hana semiconductor.
I ka hana seramika kuʻuna, spherical AlN hoʻomaikaʻi i ka homogeneity o nā kino ʻōmaʻomaʻo a hoʻohaʻahaʻa i ka porosity i nā mea sintered, e hoʻonui ana i ka hana wela a me ka mechanical.
4. Nā Kūlana Kūlana a me ka Manaʻo o ka wā e hiki mai ana
4.1 Nā ʻōnaehana uila a me ka ikehu o ka hanauna hou
Ke hoʻomau nei ka emi ʻana o ka nui o nā mea uila me ka hoʻonui ʻana i ka mānoanoa mana, ke ulu nui nei ka pono o nā lawelawe hoʻokele wela.
Ua mākaukau ʻo Round AlN e pāʻani i kahi hana koʻikoʻi i nā ʻenehana kū mai e like me 5G/6G base terminals, ʻāpana uila uila, a me ka helu helu hana kiʻekiʻe (HPC) ʻōnaehana, kahi i kaupalena ʻia ai ka maikaʻi o ke ʻoki ʻana i ka wela.
ʻO kona hoʻohui pono ʻana i loko o nā pā anu i hoʻoluʻu wai, mea hoolaha pumehana, a me nā hale hoʻoluʻu i hoʻopili ʻia e hoʻohana i nā ala hou no ka hoʻonui ʻana i ka wela o ka pae ʻōnaehana.
Ma kahi hoʻopaʻa ikehu, a puni ʻo AlN ke nānā ʻia nei ma ke ʻano he mea hoʻohui wela akā hoʻokaʻawale uila i nā mea hoʻokaʻawale pākaukau a me nā encapsulants e hōʻemi i ka holo ʻana o ka wela i nā pā lithium-ion..
4.2 Nā Luʻi Hoʻomau a me Scalability
ʻOiai kona mau pono, ʻO ka hoʻohana nui ʻana o spherical AlN e hālāwai me nā pilikia e pili ana i ke kumukūʻai, hoʻohuihui ikaika, a me ka hopena o ke kaiapuni.
Pono ka hoʻokomo mana nui i ka plasma spheroidization a me ka hoʻoulu ʻana i ka pauka maʻemaʻe kiʻekiʻe, ka hoʻomaka ʻana i ke aʻo ʻana i nā papa hana ʻoi aku ka maikaʻi a hoʻomau.
Ka hana hou ʻana o ka ʻōpala AlN a me ka ulu ʻana o nā ʻano hana synthesis like ʻole, e like me nā kaʻina hana hoʻonā a haʻahaʻa paha, he mau wahi ikaika o ka hookolokolo ana.
Eia kekahi, ʻO ka nānā ʻana i ke kaʻina hana ola a me ka ikaika o ke kaulahao e hoʻopau ʻia i mea noʻonoʻo nui e like me ka pono o ka honua no nā kumuwaiwai koʻikoʻi.
Ma ka hōʻuluʻulu, ʻO ka nitride alumini spherical ke kū nei i kahi hana hou i loko o ka hana hou o ka pauka ceramic, ka hoʻohui ʻana i ka maikaʻi wela intrinsic o AlN me ka morphology i hana ʻia no ka hana kupaianaha a me ka pono..
ʻO kāna hana i ka ʻae ʻana i nā hāmeʻa nānā wela o ka hanauna e hiki mai ana ma waena o ka uila, ikehu, a ʻo ka ʻoihana kiʻekiʻe e hoʻokūpaʻa i kāna waiwai helu i ka holomua o nā huahana kiʻekiʻe.
