抄録

In order to improve the life of saggers, three kinds of material were studied as for the sagger bodies. The physical properties of trial manufactured saggers, thermal stress for saggers of large size, and temperature gradients between the outer and inner sides of saggers in the tunnel kiln were examined. The mechanical strengths, thermal expansion, specific heat, and thermal conductivity of saggers of chamotte, cordierite, or semi silicon carbide type were measured.<br>The suitable heating or cooling rate for saggers were found to be 1.5°C/min for chamotte type, and 6°C/min for cordierite or semi silicon carbide type saggers, from thermal stress analysis.
