Abstract
The invention belongs to a method for sealing metal and glass, which adopts glass powder or ceramic powder with gradually changed expansion coefficients as a transition layer to finally seal the metal and the glass together at a lower temperature. The requirements of firmness, thermal shock resistance and air tightness are met. The invention adopts a multilayer transition method to solve the sealing stress caused by the unmatched expansion coefficients between metal and glass, can realize large-area low-temperature sealing between metal and glass with larger expansion coefficient difference, and has simple process.
Description
The invention belongs to the method for sealing of a kind of metal and glass.
At present the method for using is under the condition of high temperature (above 1000 ℃), with metal and glass simultaneously equality of temperature heat, treat that glass softens fully after, with metal and glass sealing together.This method has three main drawbacks: 1, the high temperature of need of work has surpassed the softening temperature of glass, and glass is yielding during sealing-in; 2, sealing strength is low; 3, can only be confined to the small area sealing-in.And for example number of patent application is that 93101627.4 technical scheme is described, must under high pressure just can finish sealing-in, the sealing apparatus complexity, and the production cost height, and can not be fit to the sealing-in of large-area metal and glass.
The object of the present invention is to provide a kind ofly be lower than under the temperature condition of glass softening point, realize metal and glass hermetic seal, obtain the method for one firm, heat shock resistance, sealing layer that resistance to air loss is good.
Technical solution of the present invention is: earlier suitable processing is done in the metallic surface, wait to seal: high melting point glass powder or the ceramics powder that sintering one deck coefficient of dilatation is complementary with it on the metal of having handled on the surface again obtains a high-melting-point sintered layer; Then, on the high-melting-point sintered layer with coefficient of dilatation and high-melting-point sintered layer with wait to seal the glass powder with low melting point that the glass coefficient of dilatation all is complementary and will wait to seal metal and wait to seal in the glass sealing, obtain a low melting point sintered layer, obtain simultaneously one firmly, heat shock resistance, hermetic seal structure.When mismatching when waiting to seal metal to differ big, can select the multiple glass powder of coefficient of dilatation gradual change or ceramics powder sintering successively, realize waiting to seal metal and a sealing-in of joining of waiting to seal glass with glass powder with low melting point at last with the coefficient of dilatation of waiting to seal glass.
The present invention is owing to adopted multiple glazing powder or ceramics powder as transition layer, sealing temperature is too high in the prior art, glass is yielding, sealing strength is low, be only limited to shortcomings such as small area sealing-in so overcome, and can obtain that a big area, glass are indeformable, firm, the metal and the glass sealing structure of heat shock resistance.The present invention can realize under normal pressure, overcome number of patent application and be the shortcoming of 93101627.4 technical scheme, is highly susceptible to industrial production.
Accompanying drawing is a synoptic diagram of the present invention.
Implementation:
Be example with stainless steel plate (1Cr13) with the sheet glass hermetic seal below, implementation of the present invention is described.
Earlier stainless steel plate 1 is cleaned, coefficient of dilatation is 101 * 10
-7/ ℃, be heated little red (about 600 ℃) again, make surperficial low-level oxidation.
Be coated with last layer iron sealing glass powder on stainless steel plate 1, coefficient of dilatation is 95 * 10
-7/ ℃, under 960 ℃ temperature, obtain sintered layer 2.
Coat glass powder with low melting point on sintered layer 2,450 ℃ of fusing points, coefficient of dilatation are 95 * 10
-7/ ℃, under 450 ℃ of temperature, (be lower than the softening temperature of waiting to seal sheet glass), obtain sintered layer 3, (coefficient of dilatation is 90 * 10 to finish sheet glass 4 simultaneously
-7/ ℃) with the hermetic seal of stainless steel plate 1.
Claims (2)
1, the airtight connection of a kind of metal and glass, earlier appropriate location being done in the metallic surface buries, wait to seal, it is characterized in that: sintering one deck coefficient of dilatation is complementary with it on the metal of having handled on the surface high melting point glass powder or ceramics powder, obtain a high-melting-point sintered layer, on the high-melting-point sintered layer, with coefficient of dilatation and high-melting-point sintered layer with wait to seal the glass powder with low melting point that the glass coefficient of dilatation all is complementary and to wait to seal metal and wait to seal in the glass sealing, obtain a low melting point sintered layer, obtain simultaneously one firmly, heat shock resistance, hermetic seal structure.
2, the airtight connection of a kind of metal according to claim 1 and glass, it is characterized in that: differ when being complementary more greatly and not when waiting to seal metal and the coefficient of dilatation of waiting to seal glass, can select the multiple glass powder or ceramics powder sintering, a sealing-in of joining of waiting to seal metal and waiting to seal glass with the glass powder with low melting point realization at last successively of coefficient of dilatation gradual change.
