A fiberisable mineral composition which is thermostable and has a high dissolution rate in biological fluids and which consists essentially of 56 - 65 w/w % of SiO2, </= 5 w/w % of Al2O3, 10 w/w % of CaO, 23 - 36 w/w % of MgO, and Sm(F) 8 w/w %, of FeO + Fe2O3, 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. |
