Abstract
The invention discloses a preparation method of a vacuum electronic tube packaging material. The preparation method comprises the following specific steps: (1) putting Ag, Cu, In, Ge, Co and Ni into a vacuum smelting furnace according to a ratio, vacuumizing the furnace to 0.1 to 0.5 Pa, and heating to 1,300 to 1,350 DEG C; (2) thoroughly smelting all the metal raw materials in the vacuum smelting furnace to form a melted solution, maintaining for 30 to 40 minutes, then pouring the melted solution into a sizing die, and naturally cooling to obtain a ingot casting required for machining the packaging material; (3) tempering the ingot casting, and preserving the temperature of 600 to 650 DEG C for 2 to 3 hours; and (4) performing rolling on the ingot casting through a rolling mill, and shaping and stamping the ingot casting into a required shape. The packaging material prepared by the preparation method disclosed by the invention is high in cleanness and high in corrosion and oxidization resistance.
Description
Technical field
The present invention relates to technical field of alloy material, especially relate to a kind of preparation side of radio tube seal, sealing materials
Method.
Background technology
In radio tube sealing-in industry, because radio tube usage frequency is high, and vacuum state to be kept always,
Seal, sealing materials therefore to radio tube, particularly require all to compare with the seal, sealing materials of metal with metal, metal to pottery
High.For the existing conventional seal, sealing materials radio tube high to usage frequency, effect is not ideal, such as general solder envelope
Device air tightness after connecing is not good, under long-term high frequencies of operation, antioxidation and anticorrosive property are poor etc..
Content of the invention
The problems referred to above existing for prior art, the applicant provides a kind of preparation of radio tube seal, sealing materials
Method.The seal, sealing materials cleannes that the present invention prepares are high, and anticorrosion, antioxygenic property are good.
Technical scheme is as follows：
A kind of preparation method of radio tube seal, sealing materials, comprises the following steps that：
(1) Ag, Cu, In, Ge, Co, Ni are put in vacuum melting furnace by proportioning, in stove, are evacuated to 0.1～0.5Pa,
It is heated to 1300～1350 DEG C；
(2) after each raw metal after in vacuum melting furnace, thoroughly fusing forms fused solution, holding 30～40 minutes, then
By fused solution down in shaper, natural cooling, obtain processing the ingot casting needed for this seal, sealing materials；
(3) ingot casting is carried out temper, be incubated 2～3 hours at 600～650 DEG C；
(4) and then by ingot casting carry out milling train calendering, trimmed strike out required form.
The mass percent of described each raw metal is：Cu：15～20%, In：1～3%, Ge：0.5～2%, Co：1～
2%th, Ni：3～5%；Remaining is Ag and inevitable impurity.
Beneficial the having technical effect that of the present invention：
Each raw metal is coordinated by the present invention according to a certain percentage, and the cleannes of seal, sealing materials can be made to greatly improve, thus
Make the air-tightness of the product after sealing-in better.And seal, sealing materials of the present invention have good oxidability and antisepsises,
Extend the service life of product.
