Abstract: A glass having a good hydrolytic resistance and alkali resistance is defined by a targeted combination of stoichiometric glasses, including glasses also existing as crystals in the same stoichiometry and whose properties can be assumed as being very similar due to the identical topology of the structural units for glass and crystal, respectively. A process of producing the glasses is also provided.

Abstract: A glass includes a composition which is characterized by the following constituent phases of the glass: 20-80 mol % silicon dioxide; 0-40 mol % wollastonite; 0-30 mol % cordierite; 0-40 mol % anorthite; 0-40 mol % strontium-feldspar; 0-20 mol % celsian; 0-40 mol % hardystonite; 0-10 mol % titanite; and 0-15 mol % gittinsite. Where the composition is specified in mol % relative to oxides, the glass contains less than 11.5 mol % Al2O3 and less than 5000 ppm (molar, relative to the oxides) of each of B2O3, Li2O, Na2O, K2O, Rb2O and Cs2O. A calculated value for the removal rate according to ISO 695 is not more than 81.9 mg/(dm2 3 h) and a calculated value for the removal rate in acid according to DIN12116 is less than 3.5 mg(dm2 6 h).
