SILICA GEL, PRODUCTION METHOD THEREOF, PAPER CARRYING THE SILICA GEL AND SILICA GEL ELEMENT

摘要

PPROBLEM TO BE SOLVED: To provide a silica gel having markedly high moisture absorption both under low and high humidity conditions, a paper carrying the silica gel and a silica gel element, and to provide a production method of the silica gel enabling easy synthesis. PSOLUTION: In the silica gel, the peak (maximum value) of pore size distribution is present within the range of 2.5 nm, and the ratio (VSB1/SB)/(VSB2/SB) of the total volume (VSB1/SB) of pores sized 10-25 nm to the total volume (VSB2/SB) of pores sized 2-25 nm is 0.15-0.4. The production method thereof, a sheet of paper carrying the silica gel and the silica gel element are also provided. PCOPYRIGHT: (C)2010,JPO&INPIT
