<p>A fiberisable mineral composition which is thermostable and has a high dissolution rate in biological fluids and which consists essentially of 53.5 - 64 w/w % of SiO2, ≤ 4 w/w % of Al2O3, 10 - 20 w/w % of CaO, 10 - 20 w/w % of MgO, and 6.5 - 9 w/w % of FeO, the total amount of FeO and Fe2O3 calculated as FeO. A mineral fibre material made from the composition and used for thermal and/or acoustic insulation purposes or as a plant growing medium or substrate.</p> |
