AMORPHE KIESELSÄUREPARTIKEL MIT HOHER ABSORPTIONSKAPAZITÄT UND AUSGEPRÄGTEN STRUKTURELLEN EIGENSCHAFTEN |
摘要 |
The present invention provides amorphous silica particles having high oil absorbency and high structural characteristics, wherein the oil absorbency is hardly decreased even when a high load is applied to the amorphous silica particles. In particular, amorphous silica particles are provided, wherein the maximum value of DeltaVp/DeltaRp (where Vp is the pore volume [mm<SUP>3</SUP>/g] and Rp is the pore radius [nm]) is 20 mm<SUP>3</SUP>/nm.g<SUP>-1 </SUP>or more in the pore distribution curve obtained by a benzene adsorption isotherm, and the pore peak radius when the DeltaVp/DeltaRp value is maximum is from 20 nm or more to 100 nm or less. |
