Abstract: front page image
(EN)The invention relates to mineral fibres having a chemical composition comprising the following constituents, in weight percentages: between 30 and 50% of SiO2, between 10 and 20% of Al2O3, between 20 and 35% of CaO+MgO and between 1 and 10% of Na2O+K2O, characterised in that said mineral fibres have a total iron content, expressed as Fe2O3, of between 5 and 15 % and a redox, which corresponds to the weight ratio between the ferrous iron content, expressed as Fe2O3, and the total iron content, expressed as Fe2O3, which is lower than 0.6, preferably lower than 0.5, more preferably lower than 0.4.
(FR)La présente invention concerne des fibres minérales présentant une composition chimique comprenant les constituants suivants, en pourcentages pondéraux : SiO2 30 à 50 % Al2O3 10 à 20 % CaO+MgO 20 à 35 % Na2O+K2O 1 à 10 % caractérisées en ce que lesdites fibres minérales comprennent une teneur en fer total, exprimée en Fe2O3, de 5 à 15 % et un redox, qui correspond au rapport pondéral entre la teneur en fer ferreux, exprimée en Fe2O3, et la teneur totale en fer, exprimée en Fe2O3, inférieur à 0,6, de préférence inférieur à 0,5, plus préférentiellement inférieur à 0,4.
