摘要：
Shrinkage of porous glasses on heating from 20 to 800°C was studied and temperature dependences of the viscosity in the range of 1011–1013 P were determined for quartzoid (sintered) glasses based on five glasses with different compositions in the Na2O-B2O3-SiO2 system. The shrinkage of porous glasses and the viscosity of quartzoid glasses were analyzed in relation to their composition and temperature of preliminary thermal treatment.
