DEFORMATIONS OF CERAMIC MATERIALS DURING MANUFACTURING PROCESS

Abstract

The manufacturing process of a ceramic product includes many stages that introduce deformations in the shape of the object. The shrinkage during the drying process, carried out before firing, is practically linear and hardly affects the shape of the object. However, the deformations that take place in biscuit firing and firing are clearly more difficult to predict. 

This study focuses on the deformations taking place during 
firing, aiming at establishing models of deformations of plate-like object shapes. These models will make it easier for producers of ceramics to accomplish exactly the desired end product. This study also prepares the ground for the objective that various deformation phenomenacan be taken into account in the future versions of computer-based design programs.
