I-quartz fiber yenziwe ngetshe le-quartz elicwengekile eliphakeme le-silica ngokuncibilika kwezinga lokushisa bese lidonswa kububanzi be-filament obuyi-1-15μm ye-glass fiber ekhethekile, enokumelana nokushisa okuphezulu, ingasetshenziswa isikhathi eside ekushiseni okuphezulu kwe-1050 ℃, ezingeni lokushisa 1200 ℃ noma ngaphezulu njengoba ukusetshenziswa ablative materials. Iphuzu elincibilikayo le-quartz fiber liyi-1700 ℃, elesibili ngemuva kwe-carbon fiber ngokwezinga lokushisa. Ngesikhathi esifanayo, ngenxa yokuthi i-quartz fiber ine-insulation kagesi enhle kakhulu, i-dielectric constant kanye ne-dielectric loss coefficient iyona engcono kunazo zonke phakathi kwayo yonke imicu yamaminerali. I-quartz fiber inezinhlelo eziningi zokusebenza kwezindiza, i-aerospace, i-semiconductor, ukushisa okuphezulu kokushisa, ukuhlunga izinga lokushisa eliphezulu.
