Summary:An ultra-low thermal mass refractory article includes fibers impregnated with a colloidal inorganic oxide. The refractory article has at least one of the following properties: (i) a density of 500 kg/m3 to 1500 kg/m3; (ii) a thermal conductivity of 1.0 Wm/K or less at 700°C; and/or (iii) a linear thermal shrinkage at 1400°C of less than 2.5%. Un article réfractaire à masse thermique ultra-faible comprend des fibres imprégnées d'un oxyde inorganique colloïdal. L'article réfractaire a au moins l'une des propriétés suivantes : (i) une densité de 500 kg/m3 à 1500 kg/m3 ; (ii) une conductivité thermique inférieure ou égale à 1,0 Wm/K à 700 °C ; et/ou (iii) un retrait thermique linéaire à 1400°C inférieur à 2,5 %.
