摘要：
Water-repellent porous silica having uniform pores, which comprises silica skeleton wherein fluorine atoms are fixed through covalent bonds and which has an alkali metal content of not more than 10 ppb, is synthesized. By the water-repellent porous silica, a water-repellent porous silica film having uniform pores, which is applicable to a light functional material or an electron functional material, a process for preparing the same and uses thereof can be provided.
