High temperature hermetic sealing
Glass to Metal Seals (hermetically sealed)

Pre-oxidized:A suitable oxide layer is pre-oxidized on the metal 
                      surface
as a transition zone. The transition zone thus 
                      enables the
properties of the glass to gradually change
                      to those of the
metal.
                      (Most metals require pre-oxidation)


Annealing:Reduce or eliminate the permanent stress generated during
                  the forming or thermal processing of glass, and enhance
                  the
strain resistance of glass(lens).

Remove oxide:For optimal surface treatment of metal (electroplating
                        or electrochemical polishing), the metal oxide layer    
                        must
first be removed.
