Zirconia — Sintering

During the production of high-tech ceramics, a ceramic powder is mixed with a binder and pressed to a green body. By thermal treatment the binder is removed (burned out) and the ceramic is sintered to the final part. In order to determine the quality of the final part, the binder burnout and sintering temperatures as well as the shrinkage during sintering have to be known. These properties can be measured quickly and easily using pushrod dilatometry. Presented in the figure are tests on an yttria-stabilized zirconia green body and on the sintered ceramic.
