Basalt fiber - Wikipedia
The technology of production of basalt continuous fiber (BCF) is a one-stage process: melting, homogenization of basalt and extraction of fibers. Basalt is heated only once. Further processing of BCF into materials is carried out using "cold technologies" with low energy costs. Basalt fiber is made from a single material, crushed basalt, from a carefully chosen quarry source. Basalt of high acidity (over 46% silica content ) and low iron content is considered desirable for f
