Ulusi wa quartz umapangidwa ndi mwala woyeretsedwa kwambiri wa silika wa quartz chifukwa cha kutentha kwambiri kusungunuka ndipo kenako kuchokera ku ulusi wa 1-15μm wa fiber yapadera yamagalasi, yokhala ndi kutentha kwakukulu, ingagwiritsidwe ntchito kwa nthawi yaitali pa kutentha kwakukulu kwa 1050 ℃, kutentha kwa 1200 ℃ kapena kupitirira apo monga ntchito ablative zipangizo. Malo osungunuka a quartz fiber ndi 1700 ℃, wachiwiri ku carbon fiber malinga ndi kukana kutentha. Panthawi imodzimodziyo, chifukwa quartz fiber imakhala ndi magetsi abwino kwambiri, mphamvu yake ya dielectric ndi dielectric loss coefficient ndiyo yabwino kwambiri pakati pa mineral fibers. Ulusi wa quartz uli ndi ntchito zosiyanasiyana pamayendedwe apaulendo, ndege, semiconductor, kutchinjiriza kutentha kwambiri, kusefera kwakukulu.
