ABSTRACT:
Calcium silicate insulation consisting mainly of long, mutually entangled, fibrous synthetic xonotlite crystals and having a bulk specific gravity of 0.10 to 0.20 g/cm.sup.3 is produced at a very low cost without using any asbestos fibers by stirring very fine scattered ashes consisting mostly of amorphous silica, generated from furnaces where metallic silicon, silicon carbide, ferrosilicon, etc. are produced, with lime raw materials and water with heating, thereby obtaining a gel; kneading the gel under pressure, thereby obtaining a viscoelastic material just before transition to xonotlite crystals; pouring the viscoelastic material in a mold; and treating the viscoelastic material placed in the mold under saturated steam, thereby forming crystals, and successively treating the viscoelastic material under superheated steam, thereby effecting growth and drying of the crystals.
