摘要： The invention relates to a ceramic material, comprising SiO2 and Na2O and/or K2O. Said material is characterized by a porosity of over 60 % and by pores, more than 70 % of which have a pore size ranging between 0.1 and 15 νm. The ceramic material can be used as filtering material, for water storage and as adsorbent material.
