Description
Изобретение относитс к электродному стеклу дл потенциометрического измерени в растворах активностей ионов водорода, натри , кали и других.The invention relates to electrode glass for potentiometric measurement in solutions of the activities of hydrogen ions, sodium, potassium, and others.
Известно электродное стекло, включающее ВЮг, РегОз, NaaO.Electrode glass is known, including VYuG, RegOz, NaaO.
Предлагаемое стекло обеспечивает измерение окислительного потенциала сред, имеет электронный характер проводимости. Это достигаетс тем, что оно содержит указанные компоненты в следующих количествах, вес. %; SiOz 45-65, РегОз 20-50, МагО 4-15 и, кроме того, LiaO 2-10.The proposed glass provides a measurement of the oxidizing potential of the media, has an electronic conductivity character. This is achieved in that it contains these components in the following amounts, weight. %; SiOz 45-65, RegOz 20-50, MagO 4-15 and, moreover, LiaO 2-10.
Стекло синтезируют из химически чистых порошкообразных окислов, доведенных до посто нного веса. Шихту загружают в тигель, который устанавливают в предварительно разогретую до 1100°С печь. Затем в течение 4 час температуру поднимают до 1350°С, и при этой температуре стекломассу выдерживают 1,5 час. Во врем варки расплав периодически перемеш 1вают, а по окончании варки отливают в формы.Glass is synthesized from chemically pure powdered oxides, brought to constant weight. The mixture is loaded into the crucible, which is installed in a preheated to 1100 ° C furnace. Then within 4 hours the temperature is raised to 1350 ° C, and at this temperature the glass mass is kept for 1.5 hours. During cooking, the melt is periodically mixed, and at the end of cooking it is cast into molds.
