It is known that certain glasses in the system Na2O-B2O3-SiO2 separate into two phases during heat treatment: a low-melting phase (L), containing mainly Na2O and B2O3, and a high-melting phase (H), with a high silica content. The low-melting component of these glasses is removed by treatment with acids, while the remaining high-silica skeleton forms a glass penetrated by minute pores [1, 2].
