Karāhe Whatu Hiraka Whakakotahitia a JGS1, JGS2, me JGS3

Whakaahua Matua o te Karāhe Whatu Hiraka Whakakotahi JGS1, JGS2, me JGS3

Whakaahuatanga Poto:

Ko te "Hiko Hiraka Whakakotahi" te "Kuata Whakakotahi" rānei, koinei te wāhanga kore-āhua o te kuata (SiO2). Ina whakaritea ki te karāhe borosilicate, kāore he tāpiringa o te silika whakakotahi; nō reira kei roto i tōna āhua parakore, arā, ko te SiO2. He nui ake te tuku o te silika whakakotahi i roto i te whānuitanga whero me te hihi ultraviolet ina whakaritea ki te karāhe noa. Ka puta te silika whakakotahi mā te rewa me te whakapakeke anō i te SiO2 tino parakore. Ko te silika whakakotahi hangai, i tētahi atu ringa, he mea hanga mai i ngā matū matū whai rawa i te silicon pērā i te SiCl4 ka whakakāhia, kātahi ka waikurahia i roto i te hau H2 + O2. Ko te puehu SiO2 i hangaia i tēnei take ka whakakotahitia ki te silica i runga i te papa. Ka tapahia ngā poraka silika whakakotahi kia rite ki ngā papa angiangi, ā, muri iho ka whakakanapahia ngā papa angiangi.
