Patent ID: 7530240

Claim:
The method of producing continuous inorganic fibers of rock, comprising operations of: loading fractured rocks to a melting furnace, melting the rocks to produce a melt, homogenizing the melt, further stabilizing the melt in a melting furnace feeder, drawing a fiber, and lubricating and winding the fiber onto a bobbin, wherein dacite or rhyodacite is used as a rock, prior to loading to the melting furnace the rock is heated up to temperature between 700 and 910 ° C., kept at this temperature during 5 to 15 minutes until removal of chemically bound water and burning up organic components, then the rock is subjected to mechanical-catalytical activation until obtaining particles of not more than 15 μm in size and is heated to temperature between 2105 and 2200 ° C. until obtaining the melt with amorphism degree of not less than 96% and isolation of not melted quartzites from the melt, further homogenization and stabilization of the melt are performed at the temperature 1420 to 1710 ° C. until obtaining the melt with viscosity being not less than 130 decipoise, and fibers are drawn from the melt below a surface thereof.
