Silcagel, production method thereof, silica gel-supported paper and silica gel element

摘要

The present invention provides silica gel which has remarkably increased hygroscopic capacity in low humidity and high humidity, silica gel loaded paper and a silica gel component. The invention also provides a manufacturing method of silica gel which is easily synthesized. The invention also provides the silica gel which has a peak value (greatest value) of small pore distribution in the area with the small pore diameter smaller than 2.5nm and furthermore has a ratio between the total small pore dimension (V1) with the small pore diameter of 10-25nm and the total small pore dimension (V2) with the small pore diameter of 2-25nm is 0.15-0.4, the manufacturing method thereof, the silica gel loaded paper loading the silica gel, and the silica gel component.
