INSULATING REFRACTORY MATERIAL |
摘要 |
The invention concerns an insulating refractory material comprised of 20-80 % by weight of a ceramic matrix, 5-40 % by weight of insulating microspheres, 0.5-15 % by weight of one or more binders and 0-5 % by weight of water. The ceramic matrix is comprised of vitreous grains, notably atomized silica. It also contains 0.5-4 % by weight of a deflocculant and 0.5-4 % by weight of colloidal silica. The insulating microspheres are hollow spheres of a material based on silica and alumina. They contain 55-65 % by weight of silica and 27-33 % by weight of alumina.
