Abstract
A method of sintering large refractory ceramic articles is disclosed. The method includes supporting a green refractory body on a plurality of support plates, the support plates in turn being supported by a plurality of support members having arcuate upper and lower surfaces. A setter material is disposed between the green refractory body to be sintered and the support plates. As the refractory body is sintered, the density of the article increases. Concurrently, the dimensions of the body decrease, which shrinkage, unless otherwise accommodated, may cause fracture of the body. The support plates and the structure of the support members, move to prevent the development of detrimental stresses in the refractory body as it sinters.
