Abstract
In order to form a uniform oxidation layer and spinel crystalline phase that has been help strong bonding in Kovar(Fe-29Ni-17Co)-to-glass sealing, the humidified nitrogen and nirtogen/hydrogen mixture was used as an oxidation atmosphere. Kovar oxidation was diffusion-controlled reaction and the activation energy was 25~32 kcal/mol at
