Description
Изобретение относитс к технологии силикатов, а именно стекла, которое может быть использовано в качестве защитного изол ционного материала дл толстопленочных конденсаторов, а также при изготовлении других элементов высокоточных приборов в электронной , радиотехнической промышленности и промышленности средств св зи.The invention relates to the technology of silicates, namely glass, which can be used as a protective insulating material for thick-film capacitors, as well as in the manufacture of other elements of high-precision devices in the electronic, radio and telecommunications industries.
Цель изобретени - повышение микротвердости , удельного электрического сопротивлени , снижение температуры растекани и уменьшение емкости толстопленочных конденсаторов после их защиты стеклом.The purpose of the invention is to increase the microhardness, electrical resistivity, decrease the temperature of the flow and reduce the capacity of thick-film capacitors after their protection with glass.
Составы стекол и их свойства приведены в таблице.The compositions of glasses and their properties are shown in the table.
Дл синтеза стекла используют следующие сырьевые материалы: кварцевый песок, борную кислоту, оксид висмута, оксид цинка и углекислый барий.The following raw materials are used to synthesize glass: quartz sand, boric acid, bismuth oxide, zinc oxide, and barium carbonate.
Синтез осуществл ют в корундизо- вых тигл х емкостью 0,1 кг в электрической печи с силитовыми нагревател ми по режиму: подъем температуры до 1000°С в течение 4 ч, выдержка при этой температуре 0,5 ч, выработка образцов методом лить в металлические формы.Synthesis is carried out in corundum crucibles with a capacity of 0.1 kg in an electric furnace with sieve heaters according to the mode: temperature rise to 1000 ° C for 4 hours, holding at this temperature for 0.5 hours forms.
