Structure of sintered clay samples: (a) pore structures after sintering of powders with size ranges between 45–63 μm, 𝑃=8.8%; (b) size ranges between 125–255 μm showing bimodal and interconnected pore structure, 𝑃=18.3%; (c) etched sections of samples from particle size ranges 45–63 μm showing small mullite needles (1-2 μm) and (d) etched section of samples from particle size ranges 125–255 μm showing large mullite crystals (5–7 μm).
