Cordierite was synthesized using high-purity kaolin, talc, and alumina using conventional techniques for kiln-furnitureapplication. The new raw materials subjected to magnetic separation process is to ensure total iron-free powders. Thestoichiometric mixture of clay, talc, and alumina was prepared and planetary milled for several hours. The particle sizes weremeasured after 2, 4, 6 and 8 hours of milling respectively. The Cordierite mixtures milled at different timings were then driedat 110 oC for 24 hours. The powder blend was compacted to obtain a pellet of 12.5 mm under a uniaxial press. The pressedspecimens were sent for drying and were fired at 1050, 1150, 1250, and 1350 oC. The sintered samples were subjected to Xraydiffraction (XRD). The XRD analysis indicated a clear formation of Cordierite phase for the samples sintered at 1350 oC. Scanning Electron Microscopy (SEM) studies and physical properties like bulk density, specific gravity, porosity, and waterabsorption were studied for the identified specimens. The hardness test using Vickers hardness tester was found to be in therange of 7.4-7.6-GPa, and the hot MOR was found to be 82-92-kg/cm2. A lower porosity for the specimens was also observed. All the results suggested that the Cordierite ceramics synthesized with the desired stoichiometry could be effectively used forkiln furniture applications.
Abstract
Cordierite was synthesized using high-purity kaolin, talc, and alumina using conventional techniques for kiln-furnitureapplication.

The Cordierite mixtures milled at different timings were then driedat 110 oC for 24 hours. The powder blend was compacted to obtain a pellet of 12.5 mm under a uniaxial press.
