Sep 22, 2011 This complicates the formation of continuous basalt fibers. The fiber-forming temperature range is determined by the maximum and minimum temperatures on the bushing assembly (or, more precisely, at the inlet of the nozzles) at which the fiber-forming process is stable. This range is from 1360 to 1450C for CBFs.

Jul 12, 2021 Basalt fiber is a drawn continuous fiber similar to fiberglass and carbon or aramid fibers. To produce the fiber, mined basalt rock is washed and placed into a furnace at approximately 1500C. The resulting melt is extruded through a bushing, a precious metal block with thousands of microscopic holes that each produce a single filament.
