火山ガラスを原料にした多孔質ガラス(SPG)の製造と利用

抄録

Microporous glass materials were prepared by making use of phase separation in immiscibility region of a glass of CaO-Al₂O₃-B₂O₃-SiO₂ system from volcanic glass. Because of their uniformly controlled pores and possibility of designing the pore size, various applications of the material are promising in advanced technology. Preparing process of the porous glass, their physical and chemical properties and some applications were introduced and discussed in this paper.
