“…The following dehydration and possibly also decomposition of organic matter naturally present in the raw materials and/or added to the slip as dispersant (endothermic band at T< ca. 340 • C), two important endothermic events are observed at 494 • C and 665 • C which are assigned to dehydroxylation of kaolinite and illite, respectively [80]. The α→β transition of quartz is also evident at 573 • C. An exothermic peak is observed at 960 • C and is assigned to the crystallization of primary mullite from the dehydroxylated clay minerals.…”

The digital transformation of manufacturing firms, in addition to making operations more efficient, offers important opportunities both to promote the transition to a circular economy and to experiment with new techniques for designing smarter and greener products. This study integrates Industry 4.0 technologies, smart data, Life Cycle Assessment methodology, and material microstructural analysis techniques to develop and apply a circular eco-design model that has been implemented in the Italian ceramic tile manufacturing industry. The model has been initially adopted in a simulation environment to define five different scenarios of raw material supply, alternative to the current production one. The scenarios were then validated operationally at laboratory scale and in a pilot environment, demonstrating that a proper selection of raw material transport systems significantly improves the environmental performance of the ceramic product. Both the results of the laboratory tests and of the pre-industrial experiments have demonstrated the technological feasibility of the solutions identified with circular eco-design, enabling the re-engineering of the ceramic product as the fifth of the 6Rs of the circular economy.

“…The C-130 type high strength alumina porcelain is one of the most widely used materials for preparation of high voltage ceramic insulators, which must cope with weather fluctuations for several decades. Numerous authors have studied the effect of the compaction pressure on the mechanical, microstructural, and other physical parameters (bulk density, shrinkage upon firing or water absorption) [4][5][6][7][8][9]. An increase in the mullite crystals length was reported with an increasing compaction pressure.…”

Dependence of the AC conductivity of the C-130 type electroporcelain on the compaction pressure was measured. The samples were manufactured from spray-dried mixtures using isostatic compaction in vacuum at 5 different pressures (70 MPa to 110 MPa, 10 MPa step size). AC conductivity measurements were performed at 25 different frequencies ranging from 50 Hz to 3 MHz at room temperature on samples with dimensions 10 × 10 × 3 mm3. In addition to the compaction pressure, the effect of different firing temperatures was studied (1100°C and 1200°C). The highest values of AC conductivity were observed in the case of the raw samples, due to an amount of physically and structurally bound water. Conductivity relaxation was observed after firing at 1200°C in all samples at 2.5 MHz. A small effect of the compaction pressure was observed for the raw samples and samples fired at 1200°C.
