摘要： Fumed silicon dioxide powder in the form of aggregated primary particles having a BET surface area of 175 ± 15 m
2 /g and a thickening effect, based on the BET surface area, of greater than 18 mPas g/m
2 is hydrophobicized with polydimethylsiloxane. This hydrophobic fumed silica has a BET surface area of 110 ± 25 m
2 /g. It can be used in epoxy resins. These epoxy resins in turn can be used as adhesives.

摘要： The invention relates to silicon dioxide powder in the form of aggregated primary particles, having a specific pore length L of 2.5 x 10
5 to 4 x 10
5 m/pg, wherein L is defined as the quotient from the square of the BET surface and the cumulative pore volume of 2 to 50 nm, which volume is determined by the BJH method, according to the formula L = (BET x BET)/BJH volume. The invention also relates to silanized silicon dioxide powder in the form of aggregated primary particles, having a specific pore length L of 2 x 10
5 to 3.5 x 10
5 m/pg, wherein the surface of the aggregates or parts thereof is/are coated with chemically bound silyl groups. The invention further relates to a thermal insulation material comprising the silicon dioxide powder and/or the silanized silicon dioxide powder.
