The effect of quartz content and particle size on microcracking and Young's modulus of illite-based ceramics

Original language description

Illitic clays are widely used in building ceramics, often containing variable amounts of quartz. However, the influence of quartz content and particle size on the mechanical properties of fired ceramics remains unclear. This study investigates how quartz characteristics affect microcrack formation and the development of Young's modulus (E) during the firing process of illite-based ceramics. Purified illitic clay was mixed with varying quartz sand contents (5–40 wt%) and different particle sizes (0–50 μm, 50–100 μm, 100–200 μm). Thermal analysis, dilatometry, acoustic emission (AE), and scanning electron microscopy were used to assess microcracking and E development. An increase in the quartz content resulted in a lower final E due to the formation of microcracks around the quartz grains during cooling. Finer quartz particles led to higher E values throughout the firing process compared to coarser particles. Additionally, open porosity increased with increasing quartz content. AE activity also rose with quartz particle size, indicating a more intense microcracking process during cooling. These findings suggest that both an increase in the quartz content and a larger particle size contribute to a reduction in the mechanical strength. Quartz content indirectly affects the sintering process by introducing additional porosity during the shaping of the ceramic body. The results underscore the critical role of quartz characteristics in the production of illitic ceramics.
