ABSTRACT:
In the present invention, minute spherular silica gel particles suitable as polymer catalyst carriers can easily be obtained without using organic substances simply by controlling the moisture content in a slurry of silica hydrogel particles and water. The obtained spherular silica gel particles have physical properties, such as specific surface area, average pore diameter, and pore volume, that may be easily controlled. The spherular silica gel particles also have sufficient particle strength.
