Basalt fibers are made of volcanic rock that is melted and spun. Global production capacity is increasing as they are becoming more popular for various structural engineering applications. This material was first developed in the Soviet Union, mostly for military applications. Ex-Soviet countries are still where most of the experience and production capacity is (Ukraine in particular). Given that the Soviet Union disintegrated almost 20 years ago, much of this information should be in the public domain now, but may not be so easily accessible. Those few companies that have the experience with this material are unlikely to share it.

Will it scale down ?

While lava rock is common and cheap, the melting and spinning process may be difficult. Not all basalts work, and the material has to be heated up to 1,400°C (2,550°F). This all sounds very capital intensive. Still, this can potentially be made to work on the small scale, and the fibers could displace some steel and even carbon fibers.

  • Basalt can be heated with methane from biogas and also (at least in part) with concentrating solar power
  • gasifier and syngas can be used for melting.
  • induction furnace -- can melt glass, so it should also be able to melt basalt.
  • these can all be used in combination
  • many uses for waste heat: space heating, drying biomass, steam
