He maha ngā momo o ngā hua waro hiko e ai ki ngā momo taiao whakamahinga rerekē. Ko te tikanga he whakamahinga ā-mīhini ake. Hei tauira, he rauemi pai te waro hiko mō te hiri ā-mīhini waro hiko nā te mea he pai te ātete ki te waikura matū, he kaha teitei, he pakeke teitei, he pai te ātete ki te kakahu, he iti te tauwehenga waku me te ātete ki te pāmahana teitei.
Ko te karāhe silicon (SIC) e mōhiotia ana ko te karāhe karāhe, he mea hanga mai i te onepu quartz, te coke hinu (te coke waro rānei), ngā maramara rakau (me tāpiri atu i te wā e hanga ana i te karāhe silicon matomato) me ērā atu mea. He kohuke onge anō hoki kei roto i te taiao te karāhe silicon, arā, te māpere. I roto i ngā rauemi mata kore-waikura hangarau teitei o nāianei, ko te karāhe silicon tētahi o ngā rauemi e whakamahia whānuitia ana, e ohanga ana hoki, ka taea te kī ko te onepu maitai koura, ko te onepu kore-waikura rānei. I nāianei, kua wehea te hanga ahumahi o te karāhe silicon a Haina ki te karāhe silicon pango me te karāhe silicon matomato, he tioata hexagonal ēnei e rua, ko te ōwehenga o te 3.20 ~ 3.25 me te pakeke iti o te 2840 ~ 3320kg/mm2.
