Hana ʻia ka fiber Quartz i ka pōhaku silica quartz maʻemaʻe kiʻekiʻe e ka hoʻoheheʻe ʻana o ka wela a laila huki ʻia mai ke anawaena filament o 1-15μm o ke aniani aniani kūikawā, me ke kūpaʻa wela kiʻekiʻe, hiki ke hoʻohana ʻia no ka manawa lōʻihi ma kahi kiʻekiʻe o 1050 ℃, i ka mahana o 1200 ℃ a i ʻole e like me ka hoʻohana ʻana i nā mea ablative. ʻO ka helu hoʻoheheʻe o ka quartz fiber he 1700 ℃, ʻelua wale nō i ka fiber carbon ma ke ʻano o ke kūpaʻa wela. I ka manawa like, no ka mea, ʻoi aku ka maikaʻi o ka quartz fiber insulation uila, ʻo kāna dielectric mau a me ka dielectric loss coefficient ʻoi aku ka maikaʻi ma waena o nā fiber mineral āpau. ʻO ka fiber Quartz ka nui o nā noi i ka mokulele, aerospace, semiconductor, insulation wela kiʻekiʻe, kānana wela kiʻekiʻe.
