Abstract
A material of the board type for various thermal shielding applications preferably contains 10 to 50% by weight of a mineral substance based on silica or silicates in fibrous form prepared from the fused substance, 10 to 70% by weight of clay, if necessary 10 to 60% by weight of a mineral having a needle-like crystal structure, and a small proportion of an organic binder for maintaining the mineral constituents in a coherent structure at least during fabrication, conversion and utilization of the end product. The total quantity of organic substances does not exceed 8% by weight of dry substances. The material has high temperature strength by virtue of the combination of an organic binder with a mineral binder and also has good dimensional stability.
