<p>Monolithic refractory material comprised of at least one layer (1, 2) of a first dense refractory material, a layer of foamed refractory material of a second refractory material (3), advantageously bound to the layer (1, 2). It is comprised of two external layers (1, 2) of a first dense refractory material, and a layer of foam refractory material (3) of a second refractory material inserted between the external layers (1) and (2) and bound to these layers of dense material. The material of the external layer (1, 2) and/or the material of the layer of foamed material (3) have a charge that can contain at least one adjuvant selected from the group comprised of the refractory earths, metal oxides and oxide compounds, carbides, borides, silicon oxynitrides, sialons and the thermal decomposition product of carbosilanes. <IMAGE></p> |
