摘要:
A glass composition, characterized in that it is selected from the group consisting of: a glass composition (A) with the following molar percentages: 70 to 76% of SiO2, 7 to 8% of B2O3, 5 to 6% of Al2O3, and 10 to 17% of Na2O; and a glass composition (B) with the following molar percentages: 63 to 76% of SiO2, 5 to 12% of ZrO2, 0 to 12% of B2O3, 0 to 2% of La2O3, 11 to 14% of Na2O, and 3 to 5% of K2O. The glass composition can be used in a method for assembling parts, in particular for a method of manufacturing high-temperature electrolyzers (HTEs) or high-temperature fuel cells (SOFCs).

摘要:
The method includes depositing on the entire surface of a substrate a refractory cement paste formed by a powder mainly constituted by silica and alumina and mixed with a liquid. The method includes filling the cement paste in hollow portions in a relief of the surface; performing a heat treatment to harden the cement paste after it has set to obtain a first coating layer of refractory cement; and depositing a slip on the first layer, and formed of a glass frit in suspension in a liquid. The method includes performing a heat treatment for glazing by softening and spreading the glass in order to obtain a second coating layer forming a glaze covering the first layer. The composition of the glass frit is selected to form a glass having a glazing temperature lower than 1100° C. and a glass transition temperature lower than 750° C.
