AI Technical Summary

Problems solved by technology

[0014] It can be seen from Table 1 and Table 2 that in addition to the requirements for the content of metal elements, the 430Ti alloy standard also has requirements for non-metallic elements such as N, and the content of Ti elements in Corning must be assessed in relation to the content of C or C and N In addition to assessing the content of Ti (metallic state + oxidation state), Asahi Glass Company must also assess the content of free (Free) Ti (metallic state), which brings great difficulties to smelting

Abstract

An alloy used for sealing glass contains such chemical components as Cr, Nb, C, Mn, Si, P, S, Ni, Al, Mo, Ti and Fe. Its advantages are easy smelting and high sealing quality.

Description

technical field [0001] The invention relates to a glass sealing alloy, in particular to an alloy with Fe, Cr and Nb as the matrix. Background technique [0002] At present, the glass sealing alloy widely used at home and abroad is 430Ti alloy. 430Ti alloy has been used for electric vacuum devices and glass sealing materials for more than 30 years. The corporate standards of various companies are similar. Because the origin of the glass material ore used by each glass company is different, the composition is slightly different, so the coefficient of thermal expansion of the glass is also slightly different. , but the basic requirements of all glass companies for 430Ti alloy are the same. The chemical composition of the 430Ti alloy required by the world-renowned Corning Glass Works is shown in Table 1: [0003] Table 1: (weight)% [0004] C N Mn Ni Si Al P S Cr [0005] ≤0.06 ≤0.035 ≤0.60 ≤0.50 ≤0.60 ≤0.15 ≤0.04 ≤0.03 19.5~20.5 [0006] Ti minimum A 6×(C+N) Ti maximum 0.6...
