Results are presented from the development and study of cordierite-mullite panels which are based on low-cement refractory castables (LCC) and can be used as kiln furniture. Cordierite powder was synthesized from talc, kaolin, and alumina. Synthetic cordierite aggregate was used as the main component in addition to andalusite, Kerphalite, cement Secar 71, calcined alumina, and microsilica. It was established that samples of the cordierite-based material with a mullite binder had a satisfactorily low CLTE (3.72 × 10–6 1/K), which is indicative of their excellent thermal shock resistance.
