Abstract
A method for joining two ceramic sintered bodies with a joining layer. A magnesium layer is deposited on the ceramic sintered bodies to form a magnesium nitride layer. The joining layer has a component in common with a base component of the ceramic sintered bodies. The laminate is heat treated under conditions that convert the joining layer into a material substantially identical to that of the ceramic sintered bodies, whereby a homogeneous strong laminate results. The ceramic sintered body may be either an oxide, carbide or nitride. The joining layer is a metal corresponding to the base material of the ceramic sintered bodies. After joining, the joining layer is then nitrided. The resulting laminate has improved strength, and heat and corrosion resistance properties.
