Description
Technical field
The present invention relates to a kind of glass sealing alloy, particularly a kind of is the alloy of matrix with Fe, Cr, Nb.
Background technology
At present, domestic and international widely used glass sealing alloy is the 430Ti alloy.It is year historical that the 430Ti alloy is used for surplus electron tube and the glass sealing material existing 30, the company standard of each company is similar, because different its compositions in each glass company used glass material ore place of production are slightly different, so the thermal expansivity of glass is also slightly different, but each glass company is the same to the basic demand of 430Ti alloy.Chemical Composition as the desired 430Ti alloy of world-renowned Corning Incorporated (Corning Glass Works) is as shown in table 1:
Table 1:(weight) %
C N Mn Ni Si Al P S Cr
≤0.06 ≤0.035 ≤0.60 ≤0.50 ≤0.60 ≤0.15 ≤0.04 ≤0.03 19.5～20.5
Maximum other impurity surpluses of 0.65 Fe+ of minimum A 6 * (C+N) Ti of Ti
Minimum B 8 * C
World-renowned Japan AGC company desired 430Ti alloy composition standard is as shown in table 2:
Table 2::(weight) %
C Si Mn P S Ni Cr
≤0.06 0.20～0.80 ≤0.60 ≤0.04 ≤0.03 0.25～0.35 17.5～19.5
Cu Al Ti other impurity of Ti N Fe+ that dissociate
0.05～0.15≤0.03 0.35～0.65 0.15～0.35≤0.01 surplus
From table 1 and table 2 as can be seen, 430Ti alloy standard has the requirement except that the content to metallic element, also non-metallic element such as N there is requirement, and the Ti of Corning Incorporated constituent content must connect examination with C or C and N content, Asahi Glass company is except that examination Ti (metallic state+state of oxidation) content, also must examine free (Free) Ti (metallic state) content, bring very big difficulty to smelting.
Summary of the invention
The objective of the invention is to overcome the defective of above-mentioned prior art, a kind of novel glass sealing alloy is provided.
Glass sealing alloy of the present invention, form by Cr, Nb, C, Mn, Si, P, S, Ni, Al, Mo, Ti and Fe, its weight percent is respectively 15.0～22.0%, 0.20～3.0%, 0～0.06%, 0.20～0.80%, 0～0.80%, 0～0.04%, 0～0.04%, 0～0.50%, 0～0.40%, 0～0.50% and 0～0.50%, and all the other are Fe.Certainly, the present invention also contains other elements (impurity) of some traces.

Glass sealing alloy of the present invention, can also form by Cr, Nb, C, Mn, Si, P, S, Ni, Al, Mo, Ti and Fe, its weight percent is respectively 25.0～32.0%, 0.2～3.0%, 0～0.06%, 0.20～0.80%, 0～0.80%, 0～0.04%, 0～0.04%, 0～0.50%, 0～0.40%, 0～0.50% and 0～0.50%, and all the other are Fe.Certainly, the present invention also contains other elements (impurity) of some traces.
Best, this each weight percentages of components is respectively 28.5%, 0.80%, 0.06%, 0.06%, 0.40%, 0.02%, 0.02%, 0.25%, 0.15%, 0.20%, 0 and 69.54%.
Alloy of the present invention can adopt pure metal material or iron alloy intermediate raw material, according to existing processing condition, smelts and gets at vacuum induction furnace.
Alloy of the present invention is owing to add Nb, and its content does not need to connect examination, convenient smelting with C and N content, reduce cost, in addition, when using the present invention to carry out glass sealing, not only can guarantee the sealing-in quality, and can simplify oxidizing process, reduce production costs.
