Phase separation glass

A method of making a glass article using a phase separated silicate glass comprising a first phase rich in silicon oxide and a second phase rich in boron. The phase-separated silica glass is etched with an etchant to remove at least a portion of the second phase and obtain a porous glass article of high silica content. The porous glass article may be heat treated to consolidate the porous glass article to close the pores of the porous glass article and obtain a consolidated glass article having very low dielectric properties. Various glass compositions that are phase separated by amplitude-modulated decomposition are disclosed. 一种使用包括富含氧化硅的第一相和富含硼的第二相的相分离硅酸盐玻璃制作玻璃制品的方法。相分离氧化硅玻璃用蚀刻剂进行蚀刻以除去第二相的至少一部分并获得高氧化硅含量的多孔玻璃制品。多孔玻璃制品可进行热处理以固结该多孔玻璃制品从而闭合该多孔玻璃制品的孔并获得具有非常低介电性质的经固结的玻璃制品。公开了通过调幅分解而相分离的各种玻璃组合物。
