Using a natural volcanic basalt rock as raw material, basalt roving is produced by melting the rock in a furnace at 1450-1500 degrees C. The molten material is then forced through platinum/rhodium crucible bushings to create fibers (roving). This technology, named continuous spinning, results in continuous fibers.
From there the basalt roving continuous fibers can be made into many different products
Basalt Chopped Fiber for reinforcement in various applications
Basalt Fabrics for the textile industry
Basalt Rebar and Basalt Mesh for the construction industry.
