Thermal expansion,vitrification temperature,and corrosion behavior of lead-borosilicate glasses

Data on the values of the temperature coefficient of thermal expansion (isodilates) and vitrification isotherms are presented. The chemical resistance (isochores of alkali- and acid-resistance) of lead-borosilicate glasses is studied. The behavior of the properties is studied in the ternary SiO2-B203-PbO system.
