Description
Изобретение относитс к технологии силикатов , в частности к производству легкоплавких стекол, которые могут быть использованы в электронной и радиотехнической промышленности дл герметизирующих и изолирующих покрытий по анодированному алюминию и никелированным металлическим подложкам.The invention relates to the technology of silicates, in particular the production of low-melting glasses, which can be used in the electronic and radio industry for sealing and insulating coatings on anodized aluminum and nickel-plated metal substrates.
Целью изобретени вл етс повышение температурного коэффициента линейного расширени и снижение температуры начала разм гчени . The aim of the invention is to increase the temperature coefficient of linear expansion and decrease the temperature of the onset of softening.
Дл варки эмали используют борную кислоту, свинцовый сурик, оксиды висмута и меди. Эталь вар т в корундизовых тигл х в электрической печи с силитовыми нагревател ми при 900°С с выдержкой расплава 0,5 ч.Boron acid, red lead, bismuth and copper oxides are used to cook the enamel. The etal is cooked in corundum crucibles in an electric furnace with silica heaters at 900 ° C with a melt holding of 0.5 h.
В таблице приведены конкретные составы змалей и свойства.The table shows the specific composition of the pit and properties.
