Ma'adini fiber ne Ya sanya daga high tsarki silica ma'adini dutse ta high zafin jiki narkewa sannan kuma zana daga filament diamita na 1-15μm na musamman gilashin fiber, tare da high zafi juriya, za a iya amfani da na dogon lokaci a wani babban zafin jiki na 1050 ℃, a cikin zafin jiki na 1200 ℃ ko makamancin haka kamar yadda ake amfani da kayan ablative. Matsakaicin narkewar fiber ma'adini shine 1700 ℃, na biyu kawai ga fiber carbon dangane da juriya na zafin jiki. A lokaci guda, saboda ma'adini fiber yana da kyakkyawan rufin lantarki, dielectric akai-akai da ƙarancin asarar dielectric sune mafi kyau a cikin dukkanin zaruruwan ma'adinai. Fiber Quartz yana da nau'ikan aikace-aikace a cikin jirgin sama, sararin samaniya, semiconductor, rufin zafin jiki mai girma, tacewa mai zafi.
