Camber of ceramic substrates is prevented by placing a conformable load tile over substrates during sintering. The conformable load tile has an initial curvature that facilitates escape of substrate binder gases during a burn out cycle. Subsequently, the conformable load tile conforms to the substrates under the higher heat of sintering temperature to maintain flatness of the substrates. To prevent sticking of the conformable load tile to the substrates, the conformable load tile is provided with a nonstick surface.

Weighted sintering process and conformable load tile

A stacking system includes a frame having recesses therein used to partially define openings that permit gas generated during firing of a substrate within the space defined by the frame to escape without adversely affecting the substrate. A relatively thin tile placed on the frame provides the system with an additional level for substrates.
