Abstract	A method for joining Al$_{2}$O$_{3}$ ceramics has been investigated by utilizing NiO-Al volume combustion under various pre-heating gradients in air; the ignition temperature of the system has been made clear by changing starting composition, particle size of Al, and packing density of reaction powder compacts to optimize the conditions for ceramics joining. Combustion synthesized joining layers were mainly composed of NiAl$_{2}$O$_{4}$, Ni, and NiO. In order to prevent Al$_{2}$O$_{3}$ plates cracking during the combustion process, Al$_{2}$O$_{3}$ paste containing Al$_{2}$O$_{3}$ and water glass were deposited onto the Al$_{2}$O$_{3}$ surface, which formed intermediate layer joining the reactant layer and Al$_{2}$O$_{3}$ ceramics and decreased the temperature gradient between the two layers.
