Glass-to-metal seals starting with the early Houskeeper or Vacuum tube seals, and advancing to elaborate SOFC fuel cells, and beyond.
In order to solve the problem of mechanical stresses in the seal (metals generally have a linear thermal expansion coefficient considerably greater than typical borosilicate glasses), the ECM Lab Solutions offers several furnaces for glass to metal sealing with oxidation (for surface preparation) and thermal treatment.
Because of high added value applications and very compact dimensions, our range of vacuum furnaces are perfect for laboratory and R&D environment.
Glass to metal sealing are made with metals or alloys having a value of coefficient of linear thermal expansion very close to that of the glass used in the temperature range comprised between ambient temperature and the glass annealing one.
