Abstract

The invention relates to a borosilicate glass with a linear thermal expansion between 20 and 300 °C of 3.9 to 4.5*10-6 K-1 for the production of laboratory, household, pharmaceutical container, lamp and flat glass and other special technical glasses which can be fully electrically melted and conditioned in cold-top conditions. For fixing the glass composition, this requires, besides the attainment of the desired glass properties, a consideration of the specifics of the fully electric melting process and therefore results in a limited range of variation of several glass oxides, the exclusion of the use of some raw materials, the choice of suitable refining agents, etc. The composition of the glass is SiO¿2? + ZrO2 77,0 to 81,0 % wt.; B2O3 + Na2O + K2O + CaO + MgO + BaO 16,0 to 18,5 % wt.; of which Na2O + K2O + CaO + MgO + BaO 5,4 to 7,0 % wt.; of which CaO + MgO + BaO to 0,9 % wt.; Al2O3 3,7 to 4,9 % wt.; Cl?-¿ 0,05 to 0,4 % wt.; CeO 0,0 to 1,0 % wt.; with the relations: ratio CaO + MgO + BaO / ZrO¿2? 0,0 to 1,5; ratio Na2O + K2O + CaO + MgO + BaO / B2O3 + SiO2 + Al2O3 + ZrO2 0,060 to 0,075. Only NaC1 or KC1 is used as a refining agent. A change between this glass and borosilicate glass 3.3 is reversible, repeatable as often as desired and possible within a short time.
