摘要
FIELD OF THE INVENTION The present invention relates to a process for the production of artificial glassy fibrous products by forming and melting mineral melt (s), which comprises determining the melt viscosity and fiber dissolution rate of the composition at a pH of 4 to 5 and then at 1400 ° C. a composition having a viscosity of at least 20 nm / day at pH 4.5 and containing 32-48% SiO2, 16-30% Al2O3, 10-28% CaO by weight of oxide is selected 2-20% MgO, 2-15% FeO, 0-12% Na2O + K2O, 0-4% TiO2 and 0-8% other elements. The composition is used to make artificial glassy fibers. ŕ
