Abstract
A mineral fiber composition which is soluble in biological fluids contains substantially45-65% by weight of SiO2 15-40% by weight of CaO0-20% by weight of MgO0-6% by weight of Na2O+K2Oand in addition aluminium and/or iron oxides as well as phosphorus oxide in such amounts that the weight ratio of P2O5 to the sum of Al2O3 and iron oxide is circa 0.4 to 6.
