Abstract
1,270,477. Ceramic-metal seals; brazing. COMMISSARIAT A L'ENERGIE ATOMIQUE. 1 May, 1970 [8 May, 1969], No. 21102/70. Headings B3R and B3V. [Also in Divisions C6-C7] A ceramic-to-metal seal comprises a portion formed from an alloy, containing more than 50% by weight of Ni and having a coefficient of thermal expansion of 110 to 150 x 10<SP>-7</SP> per ‹ C., bonded by a brazing alloy to a ceramic portion formed from magnesia. Suitable Ni alloys are (1) Ni 80%, Cr 20%; (2) Ni 60%, Cu 33%, Fe 6À5%; (3) Ni 60%, Fe 20%, Mo 20%; and (4) Ni 80%, Cr 14%, Fe 6%. The brazing alloy is preferably the silver-copper eutectic which may contain Ti or Zr, e.g. 0À5% Ti in hydride form. Alternatively, separate sheets of brazing alloy and active metal may be used. The ceramic may be metallized with Ti or Zr hydride or Mo-Mn, Fe-W or Mo-Ti mixtures, e.g. in powder form in an organic binder. Additionally, the Ni alloy may be coated with copper electrolytically. An example of magnesia is given which includes 95À91% MgO and a number of minor constituents. The magnesia is mixed with 0À1 to 1% titanium dioxide, e.g. 0À25%, and with 0À1% of a lubricant, e.g. zinc behenate, to avoid flaws when moulding the magnesia, e.g. to form a closure for brazing in the end of a Ni-alloy tube. Although the coefficients of expansion of the tube and closure material are substantially the same, the ceramic is under slight compression by the tube after the seal has cooled.
