ʻO ka quartz i hui ʻia

Ma ka hana Si a me FeSi, ʻo ka kumu nui Si ʻo SiO2, ma ke ʻano o ka quartz.Hoʻopuka nā pane me SiO2 i ke kinoea SiO e hana hou aku me SiC iā Si.I ka wā hoʻomehana, e hoʻololi ka quartz i nā hoʻololi SiO2 ʻē aʻe me ka cristobalite e like me ka pae wela kiʻekiʻe.ʻO ka hoʻololi i ka cristobalite kahi hana lohi.Ua noiʻi ʻia kona helu no nā kumu quartz ʻenehana a ua hōʻike ʻia he ʻano like ʻole ma waena o nā ʻano quartz like ʻole.Ua aʻo pū ʻia nā ʻokoʻa ʻē aʻe o ka ʻano i ka wā e hoʻomehana ai ma waena o kēia mau kumu quartz, e like me ka hoʻohaʻahaʻa ʻana i ka mahana a me ka hoʻonui ʻana o ka leo.E pili ana ka lakio quartz-cristobalite i ka nui o nā hopena e pili ana iā SiO2.Kūkākūkā ʻia nā hopena ʻoihana a me nā hopena ʻē aʻe o ka ʻokoʻa i ʻike ʻia ma waena o nā ʻano quartz.Ma ka hana o kēia manawa, ua hoʻomohala ʻia kahi ʻano hoʻokolohua hou, a ua hōʻoia ka hoʻokolokolo ʻana i kekahi mau kumu quartz hou i ka ʻokoʻa nui i ʻike mua ʻia ma waena o nā kumu like ʻole.Ua aʻo ʻia ka hoʻihoʻi hou ʻana o ka ʻikepili a ua noiʻi ʻia ka hopena o ka ea kinoea.Hoʻokomo ʻia nā hopena o ka hana mua i kumu no ke kūkākūkā ʻana.

Loaʻa i ka quartz fused maikaʻi loa nā waiwai wela a me nā mea kemika ma ke ʻano he crucible no ka ulu ʻana o ka kristal hoʻokahi mai ka heheʻe ʻana, a ʻo kona maʻemaʻe kiʻekiʻe a me ke kumu kūʻai haʻahaʻa he mea hoihoi loa ia no ka ulu ʻana o nā kristal maʻemaʻe kiʻekiʻe.Eia nō naʻe, i ka ulu ʻana o kekahi mau ʻano kristal, pono kahi papa o ka uhi kalapona pyrolytic ma waena o ka hehee a me ka quartz crucible.Ma kēia ʻatikala, wehewehe mākou i kahi ala no ka hoʻopili ʻana i ka uhi kalapona pyrolytic e ka lawe ʻana i ka mahu.Hōʻike ʻia ke ʻano hana maikaʻi i ka hāʻawi ʻana i ka uhi ʻokoʻa like ʻole ma kahi ākea o nā nui a me nā ʻano crucible.ʻO ka hopena o ka pyrolytic carbon coating i hōʻike ʻia e nā ana attenuation optical.I kēlā me kēia kaʻina hana uhi, hōʻike ʻia ka mānoanoa o ka uhi ʻana e hoʻokokoke i kahi waiwai hope me kahi huelo exponential e like me ka piʻi ʻana o ka lōʻihi o ka pyrolysis, a ʻo ka mānoanoa awelika e hoʻonui i ka laina me ka ratio o ka nui o ka mahu hexane i loaʻa i ka ʻili o ka pyrolytic. ka uhi ʻana.Ua hoʻohana ʻia nā crucibles Quartz i uhi ʻia e kēia kaʻina no ka ulu maikaʻi ʻana a hiki i ka 2-in-diameter Nal single crystals, a ua ʻike ʻia ka maikaʻi o ka ʻili o ka kristal Nal e hoʻomaikaʻi i ka piʻi ʻana o ka mānoanoa o ka uhi.
