摘要：

Spherical porous silica glasses whose average diameter is 40 mum are synthesized by the sol-gel process in W/O emulsions and a successive thermal treatment. The interconnected pore structure was seen in the particles. The pore size can be controlled by changing temperature of thermal treatment. The presence of residual carbons can be avoided by decreasing unreacted alkoxides with increasing water content of the initial solution in the sol-gel process.
