Ko ngā tauira whakarārangitanga o te kōpaka e puta mai ana i ngā tukanga hurihuri me te whakamahana te mea nui e wehewehe ana i waenga i ēnei momo maitai silicon e rua. Mā tēnei whakarārangitanga ka whakatau tika i ō rātou hanganga matū, ngā āhuatanga aukume, me ngā āhuatanga miihini—ngā āhuatanga e mahi ana hei paearu matua mō te whiriwhiri rauemi i roto i ngā tono ahumahi.
1.1 Ngā Rerekētanga Hanganga me te Hanganga
Ko te koiri maitai silicon e aro ana ki te witihe rite te ahunga o ngā kakano, ā, he aukume te anisotropy; he nui te silicon kei roto i te nuinga o te wā, mai i te 3.0% ki te 4.5%, ā, me uaua ngā tukanga hanga me te whakahaere kounga pakari. He rerekē, he tohatoha kakano matapōkere te maitai silicon kore-whakaaro, ā, he aukume te isotropy. Ko te nui o te silicon kei roto i te 0.5% ki te 3.0%, he pai mō te hanga papatipu me te whānuitanga o ngā tono ahumahi.
1.2 Ngā Rerekētanga o ngā Āhuatanga Aukume
He nui te uruhanga aukume o te maitai silicon e anga ana ki te witi, ā, he iti noa te ngaronga o te rino i te ahunga hurihuri; heoi, he pai rawa atu mō ngā papa aukume pūmau kotahi-angihanga, nā te mea he ngoikore ōna āhuatanga aukume i te ahunga whakawhiti.Ko te koiri maitai silicon kore-aronga, i tetahi atu taha, ka tukuna he āhuatanga aukume maha-aronga ōrite i raro i ngā papa aukume hurihuri hihiri, ahakoa he iti ake te uruhanga aukume me te mahi ngaronga rino i ērā o te maitai silicon e aro ana ki te witi.
1.3 Ngā Rerekētanga o te Utu me ngā Whakatakotoranga
Hei rauemi aukume motuhake, kounga teitei, ka whakatakotoria e te maitai silicon aro-kikokiko he whakaritenga hangarau tino pakari mō te hanga taputapu hiko tino tika, ka hua ake he utu whakaputa teitei ake. Ko te maitai silicon kore-aronga, e tohuhia ana e tōna utu whai hua me ngā whakaritenga paerewa, he whiringa pai mō te hanga papatipu o ngā taputapu hiko-ā-whānui.
