摘要

"Partu00ecculas of su00eclica amorphous having high absorption capacity and structural caracteru00ecsticas superiors".The present invention provides particles of amorphous silica having high absorption capacity and high structural characteristics.In the capacity of oil absorption is severely reduced, even when a high load is applied to the particles of amorphous silica.In particular, particles of amorphous silica is provided, in which the maximum value of 30 VP / 30 pr (where VP is the pore volume u00a2mmu00ac 3u00ac / g! And RP is the radio times u00a2nm!) Is 20 mmu00ac 3u00ac / nm.Gu00ac - 1u00ac or more on the pore distribution curve obtained by a method of isotherm adsorption of benzene and the radius of the peak pore when 30 VP / 30 PR is up to 20 nm or more to 100 nm or less.
