The basalt fibers production process can be divided in the following steps. First the basalt is melted at a temperature of 1,400 ° C (2550 ° F). The molten rock is then extruded through small nozzles for the production of filaments of basalt fibers. The high modulus of elasticity of the product results in an excellent tensile strength which is two times bigger than the tensile strength of steel.
