More Information
Summary:There is prepared pyrogenically produced silicon dioxide-mixed oxide having a BET surface area of 50 to 400 m2/g which contains as a constituent of the mixed oxide: 0.01 to 10 weight % zirconium dioxide or 0.01 to 10 weight % iron oxide (ferric oxide) or 0.01 to 9.9 weight % titanium dioxide. Because of the doping with the foreign oxide the silicon dioxide-mixed oxide is more temperature stable than the undoped silicon dioxide. The product can be used as thermal insulation either as unpressed material in free bulk form or as a compacted mixture.
