.... Glass B showed less than 8% change of the CTE during annealing time at 800 ° C , while Glass C exhibited superior long-term thermal stability, where the change of the CTE was within the equipment detection limit after being heat treated for 300 h at 800 ° C . The good thermal stability of Glass C...

... metals contained metallic Ag and Cu phases, along with continuous titanium oxide layers at the filler metal-zirconia interfaces. The brazed joints were then aged at 700 ° C for up to 100 h in air or while separating H 2 and air atmospheres. After annealing in air for 100 h at 700 ° C , degradation...
