Description
Известна паста дл металлизации форстеритовой .керамики, содержаща молибден, св зку и растворитель с добавками марганца и титана или его соединений. Однако паста такого состава неустойчива при работе ламп в атмосфере с повышенной влажностью.A known paste for the metallization of forsterite ceramics containing molybdenum, a binder and a solvent with additions of manganese and titanium or its compounds. However, a paste of this composition is unstable when lamps are operated in an atmosphere with high humidity.
Предложенна паста отличаетс от известной тем, что в .ее состав введена добавка алунда в количестве 0,8-6,1о/о общего веса ласты.The proposed paste differs from the known one in that in the composition of the composition the addition of alundum is introduced in the amount of 0.8-6.1 ° / o of the total weight of the flippers.
Предложенный состав пасты позвол ет повькить влагостойкость опа керамики с металлом .The proposed composition of the paste makes it possible to remove the moisture resistance of opa ceramics with metal.
Введение алунда в состав пасты .позвол ет снизить температуру разм гчени стеклофазы при вжигании пасты в керамику до 1150- 1200°С. В этом -случае -стеклофаза, разм гча сь (температура вжитани пасты 1280- ), значительно лучще проникает в слой металлизации и цементирует все зерна молибдена , предохран тем самым их от коррозии.The introduction of an alundum into the composition of the paste makes it possible to reduce the temperature of softening of the glass phase upon burning the paste into ceramics to 1150-1200 ° C. In this case, the glass phase softens (the temperature of the paste is 1280-), penetrates much better into the metallization layer and cements all the molybdenum grains, thereby protecting them from corrosion.
Молибденова паста, содержаща алунд и гидрид титана, опробована и дала положительные результаты.Molybdenum paste containing alund and titanium hydride was tested and gave positive results.
Предложенна паста имеет следующий состав (в Вес. о/о):The proposed paste has the following composition (in weight. O / o):
биндер (органическа binder (organic
св зка)connection)
изоамилацетат (органический растворитель) Процентное содержание вз то по весу в пределах реальных границ дл получени необходимого качества. Так, паста испытывалась в камере влаги в течение 30 суток, как это прин то в производстве приборов. Какихлибо следов разрущели такой пасты не наблюдалось , в то врем как паста старого состава за это (Врем разрущилась полностью.isoamyl acetate (organic solvent) The percentage is taken by weight within the real limits to obtain the required quality. Thus, the paste was tested in a moisture chamber for 30 days, as is customary in the manufacture of devices. Any traces of the destruction of such a paste were not observed, while the paste of the old composition during this (Time collapsed completely.
Введение в любую молибденовую пасту алуида позволит рещить задачу повышени влагостойкости спаев электрова1куумных приборов .The introduction of aluid into any molybdenum paste will make it possible to solve the problem of increasing the moisture resistance of the junctions of electric appliances.
Предмет изобретени Subject invention
1.Паста дл металлизации форстеритовых керамических деталей металлокерамических ламо, содержаща молибден, титан или его соединени , св зку и растворитель, отличающа с тем, что, с целью повышени влагостойкости спа керамики с металлом, в ее состав введен алунд. 3 алунд (Порошок)0,8-6,1 биндер (св зка) 210263 4 изоамилацетат (растворитель ).1. Paste for the metallization of forsterite ceramic parts of metal-ceramic lamos containing molybdenum, titanium or its compounds, a binder and a solvent, characterized in that, in order to increase the moisture resistance of a ceramic ceramic with metal, alundane is added to its composition. 3 Aluds (Powder) 0.8-6.1 Binder (bond) 210263 4 isoamylacetate (solvent).
