Analysis of Thermal Stresses on Core Setters

Ceramic shapes can develop internal stresses through various stages in the sintering process, such as residual stresses and pyroplastic deformation. Residual stresses occur during the temperature changes, whereas pyroplastic deformation is due to viscous flow or dislocation motion in the ceramic.

In this white paper, Phil Geers, Senior Market Manager – Molten Metals, analyzes the stresses on core bodies and various processing methods to help constrain and control these variances. To effectively work in the firing environment, ceramic core setters are required to have the following properties:

  • Resistance to slumping and movement after repeated firing
  • High tolerance capability 
  • The ability to make complicated geometry to match the ceramic core
