“…According to relevant studies, 15,16 WA is a crucial parameter for assessing ceramic tile quality in ceramic manufacturing, and this value should be below 0.5% as per ISO 10545–3–2018. 17 Thusly, contour lines of WA values can be derived and displayed in Figure 2(d) to (f). In Figure 2(d), it can be seen that the WA values of all the samples sintered at 1125 °C exceed 5.0%, since this sintering temperature (1125 °C) is insufficient to promote densification.…”

Owing to the high expenses and numerous potential avenues for formula research in ceramic production, obtaining cost-effective and high-quality ceramic formulas for high-performance ceramics poses significant challenges. To address this issue, a flux formula optimization procedure is proposed to develop the predictive ceramic formula P18, which allows precise control of the Al/Si ratio and is compatible with standard manufacturing processes. This cost-effective method enables the visual examination of ceramics’ physical, mechanical and thermodynamic properties. It is found that sintering temperature plays a crucial role in phase and microstructure evolution by classical phenomenological kinetic theory. Moreover, the sintered sample P18 exhibits remarkable mechanical performance, with a strength of 96.82 ± 2.0 MPa and fracture toughness of 1.89 ± 0.02 MPa·m1/2. These outstanding properties can be attributed to the reinforcing effects of multiple phases, such as high-strength corundum and in situ mullite whiskers. The mechanical mechanisms of the resulting ceramic tiles include particle reinforcement, microcrack deflection, intergranular and transgranular fracture, and in situ mullite whisker bridge pull-out, which collectively contribute to increase energy consumption per unit length, thus reducing the risk of brittle fractures.

“…Currently, industrial facilities regulate the moisture content levels of atomized powder to ensure that it remains within a specified maximum variation range of 1 wt.%. [54][55][56][57] Yet, achieving this target can be challenging. Thus, the suggested simulations can be useful to demonstrate how this might be attained in a more straightforward method, reducing experimental trials.…”

Reducing the environmental impact of porcelain tile production while maintaining cost‐effectiveness is challenging. This work introduced a novel modeling approach for optimizing a standard composition range comprising kaolinite (15–38 wt.%), illite (0–20 wt.%), quartz (20–40 wt.%), and feldspar (20–45 wt.%) to establish a robust composition interval for porcelain stoneware tiles. The proposed study considers several factors, such as composition impact on the manufacturing sequence, production costs, and CO2 emission. A flowsheet simulation database was generated by coupling the Dyssol framework with MATLAB. This study investigated the influence of raw material composition within the process sequence, the total CO2 emissions, and production costs within the contexts of Spain and Brazil, two of the top five global producers. Granules with a higher proportion of talc and illite exhibit reduced moisture content after spray drying, and these combinations have lower green body porosity after compaction. The addition of talc allowed for decreased porosity content after compaction reduced firing temperature, and lowered costs and CO2 emissions despite the higher prices associated with talc. The proposed simulation methodology offers a powerful decision‐making tool for optimizing raw material composition to minimize cost and CO2 emissions in the porcelain tile production. This methodology represents an early stride toward integrating digital twin methodologies within the ceramic tile sector, facilitating improved process regulation, and promoting the adoption of digital technologies.
