Method of forming a porous glass substrate

摘要

A glass material is formed from SiO2, CaO, Na2O and P2O5 and the porous, non-crystalline structure is most preferably created by melting the constituents, cooling and pulverizing the resulting glass, and then forming and hot pressing the powder. The glass of the present invention may be formed to produce templates that are useful for various indications, as well as granules that may be formed into a paste.
