one refractory plant I worked with, the kiln furniture was becoming a constant headache. Cordierite shelves were cracking after roughly 40\u201350 cycles between 1250 \u00b0C and room temperature, forcing unplanned shutdowns every six to eight weeks. The production team had tried mullite and even some silicon carbide prototypes, but nothing gave consistent life without driving costs through the roof. We eventually switched the critical setter plates and saggers to a 95 % alumina ceramic body. Within the first year the average service life climbed to more than 180 cycles, and the number of emergency kiln stops dropped by more than half.
