muka karāheHe rauemi muka karāhe te muka, ko tōna wāhanga matua he silicate. He mea hanga mai i ngā rauemi mata pērā i te onepū quartz parakore me te kōhatu kōhatu mā te tukanga rewa pāmahana teitei, te fibrillation me te totoro. He tino pai ngā āhuatanga ā-tinana me te matū o te muka karāhe, ā, he whānuitia te whakamahinga i roto ite hanga, te rererangi, te motuka, te hikohiko, me te mana hiko.
Ko te silicate te wāhanga matua o te muka karāhe, ko ngā huānga matua ko te silicon me te hāora. Ko te silicate he matū i hangaia mai i ngā katote silicon me ngā katote hāora, ko tōna tauira matū ko te SiO2. Ko te silicon tētahi o ngā huānga tino nui i roto i te kiri o te whenua, ko te hāora ia te huānga tino nui i roto i te kiri o te whenua. Nō reira, he tino noa ngā silicate, te wāhanga matua o ngā muka karāhe, i runga i te whenua.

Ko te tukanga whakarite muka karāhe me whakamahi tuatahi i ngā rauemi mata parakore teitei, pērā i te onepū kiripaka. He nui te hauhā silicon (Si02) kei roto i ēnei rauemi mata. I te wā o te tukanga whakarite, ka rewahia ngā rauemi mata hei wai karāhe. Kātahi ka totorohia te wai karāhe hei āhua muka mā te tukanga fibrillation. Hei whakamutunga, ka whakamataohia te karāhe muka ka whakamataohia kia hanga he muka karāhe.
muka karāheHe maha ngā āhuatanga tino pai o te muka karāhe. Tuatahi, he kaha, he pakari hoki tōna, ā, ka taea te ātete i ngā kaha pēnei i te kume, te pēhanga me te piko. Tuarua, he iti te mātotoru o te muka karāhe, ā, he māmā te hua. Hei tāpiri, he pai hoki te ātete ki te waikura me te pāmahana teitei o te muka karāhe, ā, ka taea te whakamahi mō te wā roa i roto i ngā taiao uaua. Hei tāpiri, he pai hoki ngā āhuatanga ārai hiko me ngā āhuatanga oro pai o te muka karāhe, ā, he whānuitia te whakamahinga i roto i te mara ohikohiko me te oro.
