Abstract (en)

[origin: EP1602425A1] Granulate as an insulating or separation means for high temperature applications containing Si dioxide obtained from amorphous Si dioxide powder containing at least 90% SiO 2 by granulation with addition of water and drying. An independent claim is included for a method of obtaining the granulate by mixing SiO 2 with water in solid to water ratio 1:0.25-1:1.5, and granulation and drying of the granulate, where the SiO 2 powder contains at least 90% amorphous SiO 2.
