Al_2O_3-SiO_2 CERAMIC MATERIALS FOR ELECTROVACUUM GLASS WELDS IN THE GLASS ELECTRODES OF pH-METERS

摘要

The results of research on obtaining Al_2O_3-SiO_2 based electric-insulation ceramic materials using ceramic mixes containing fireclay as a plastic component and silica-containing materials -- crystalline quartz (quartz sand) and amorphous silicon (silica-gel) -- to secure the required properties are presented.
