<P>PROBLEM TO BE SOLVED: To provide a porous glass which can broadly control the formation of a porous structure. <P>SOLUTION: A method of manufacturing a porous glass includes: a first step of forming a surface layer containing a boron compound and an alkali metal compound as main ingredients on a matrix glass containing a silicon oxide, a boron oxide and an alkali metal oxide; a second step of heat treatment the matrix glass and the surface layer for phase separation to form a phase-separated glass; and a third step of acid treatment the phase-separated glass to form the porous glass having pores. <P>COPYRIGHT: (C)2012,JPO&INPIT |
