He pumau ngā āhuatanga matū o te Alpha-alumina, he ātete ki te waikura, he pakeke, he pai ngā āhuatanga whakamarumaru, he teitei te ira rewa me te pakari, ā, e whakamahia ana i roto i ngā mara rerekē.
Te whakamahinga o te paura α-alumina i roto i ngā uku
He momo rauemi uku hou ngā uku alumina moroiti-kirikiri, he hanganga ōrite, he matotoru hoki, ā, he rahi te kōpura nano, iti iho rānei i te moroiti-kirikiri. He painga tōna, arā, he kaha miihini teitei, he ātete ki te kakahu, he ātete ki te waikura, he ātete ki te waikura, he tauwehenga whānui ka taea te whakarerekē, ā, he pai te pumau o te wera. Ko tōna āhuatanga matua ko te iti o te tioata tuatahi. Nō reira, ko te tikanga hangarau tino nui mō te whakarite i ngā uku alumina moroiti-kirikiri ko te whakarite i te paura α-Al2O3 me te tioata taketake iti me te kaha whakapūkara teitei. Ka taea e tēnei paura α-Al2O3 te huri hei tinana uku matotoru i te pāmahana whakapūkara iti.
Te whakamahinga o te paura α-alumina i roto i ngā rauemi ātete-wera
He rerekē te paura α-Al2O3 i roto i ngā rauemi ātete-waikura i runga i te whakamahinga, ā, he rerekē anō hoki ngā whakaritenga paura. Hei tauira, ki te hiahia koe ki te tere ake te whakakīkī o ngā rauemi ātete-waikura, ko te nano-alumina te whiringa pai rawa atu; ki te hiahia koe ki te whakarite i ngā ātete-waikura āhua, me whakamahi koe i te paura α-Al2O3 he matotoru ngā kakano, he iti te mimiti, ā, he kaha te ātete ki te hurihanga. He pai ake ngā tioata āhua-pēra, āhua-pereti rānei; engari ki te mea he rauemi ātete-waikura kore-āhua, me pai te rere o te α-Al2O3, te kaha o te mahi sintering, me te nui o te kiato o te rahi matūriki, ā, he pai ake ngā tioata kikokore.
Te whakamahinga o te paura α-alumina i roto i ngā rauemi whakakanapa
He rerekē ngā rauemi e hiahiatia ana mō ngā whakamahinga whakakanapa rerekē. Ko ngā hua mō te whakakanapa taratara me te whakakanapa waenga e hiahiatia ana he kaha tapahi kaha me te pakeke teitei, nō reira me matotoru te hanganga moroiti me ngā tioata; ko te paura α-alumina mō te whakakanapa pai e hiahiatia ana kia iti te taratara o te mata me te kanapa teitei o te hua kua whakakanapahia. Nō reira, ko te iti o te tioata tuatahi o te α-Al2O3, ko te pai ake.
Te whakamahinga o te paura α-alumina i roto i te rauemi whakakī
I roto i te rauemi whakakī, kia pai ai te whakakotahitanga ki ngā mea rauropi, kia whakaitihia ai hoki te pānga ki te matotoru o te pūnaha, ko te whakaritenga matua mō te α-Al2O3 ko te pai o te rere o te wai, he porowhita te pai, nā te mea he porowhita te mata. Ko te iti o te pūngao, he pai ake te rere o te mata o te pōro; tuarua, ko te paura α-Al2O3 me te whanaketanga tioata katoa, te parakore matū teitei me te taumaha motuhake teitei he pai ake te kawe wera me te pānga pai ake ina whakamahia mō ngā rauemi whakamahana me te kawe wera.
Te whakamahinga o te paura α-alumina i roto i te rauemi corundum capacitor
I roto i te ahumahi, he maha ngā wā ka whakakorikoria te paura α-alumina parakore ki roto i te oumu hiko pāmahana teitei hei hanga i te korundum horihori, e mōhiotia ana ko te korundum hanumi. He tino pakari tēnei rauemi, he mārama ngā taha me ngā kokonga, ā, he tata porowhita te hanganga moroiti. I roto i te tukanga huri tere-teitei, he kaha te kaha tapahi o ngā kongakonga whakakoi, ā, kāore e ngāwari te whati o ngā kongakonga whakakoi, ā, ka roa ake te ora o te mahi.
