Description
Известна паста дл металлизации керамических изделий на основе молибдена и марганца не позвол ет получить надежные металлокерамические спаи, поскольку некоторые припои, например медь, легко проникают в металлизационный слой, наруша тем самым его св зь с керамикой.The known paste for the metallization of ceramic products based on molybdenum and manganese does not allow to obtain reliable cermet joints, since some solders, such as copper, easily penetrate into the metallization layer, thereby disrupting its connection with ceramics.
Описываема паста при температуре вжигани 1270-1350°С позвол ет получить прочные вакуумплотные спаи керамики с металлом , маловосприимчивые к режимам пайки.The described paste at a firing temperature of 1270–1350 ° C makes it possible to obtain strong vacuum-tight junctions of ceramics with metal, which are poorly susceptible to soldering regimes.
Зто достигаетс тем, что паста дополнительно содержит нитрид бора в количестве 2-15i /o по весу.This is achieved by the fact that the paste additionally contains boron nitride in an amount of 2-15i / o by weight.
Питрид бора может быть введен в молибдено-марганцевые пасты вместе с такими известными добавками, как гидрид титана, стекло и др.Pitride boron can be introduced into molybdenum-manganese pastes together with such well-known additives as titanium hydride, glass, etc.
Паста содержит в % по весу:Paste contains in% by weight:

Примен емые дл приготовлени пасты порошк И должны содержать не менее SSo/o зерен размером до 3 мкм.The powder used for the preparation of the paste must contain at least SSo / o grains up to 3 µm in size.
Введение нитрида бора в пасту преп тствует проникновению частиц припо в переходный слой, предотвраща разъединение металлоизоционного сло и повыша прочность сцеплени последнего с керамикой.The introduction of boron nitride into the paste prevents the penetration of solder particles into the transition layer, preventing separation of the metal-insulating layer and increasing the strength of adhesion of the metal with ceramics.
