“…7 On the one hand, the liquid phase benefits the growth of mullite and the densification of the body, thus improving the strength of the substrate. But the liquid phase, on the other hand, can make the severe decomposition of SiC, leading to the foaming or expansion of the body, 7,8,12 which will deteriorate the product performance. So understanding the relationship between phase composition, microstructure, and properties of CPW-based porcelain tiles in detail is helpful to control the accurate process behaviors and improve the properties of the final products.…”

This landfill will cause not only serious environmental problems but also a waste of resources 9,10 .…”

Polished ceramic products are currently the most popular in architectural decoration, but a significant amount of ceramic polishing waste (CPW) is produced during the preparation process. Determining how to handle the CPW is a pressing task for enterprises. This work investigated the feasibility of recycling CPW in porcelain tile, and its influence on the phase composition, microstructure, and properties of the ceramic body. The CPW was found to have a similar composition to the traditional ceramics and worked as a flux. The SiC within CPW began to decompose into SiO 2 with CO 2 generation at about 1100°C, resulting in a porous structure. Microstructure observation indicated that a high CPW sample produced sufficient liquid phase when fired at temperatures ≤1100°C, which was not only beneficial for mullite growth but also for matrix densification by the viscous flow mechanism. But a high-content CPW caused the body to foam or even expand at temperatures >1100°C, thus significantly reducing mechanical properties. Finally, a series of porcelain tiles were successfully prepared with a CPW content of ≤30 wt% at a firing temperature of 1125-1200°C.The results of this study are considered to be valuable for the utilization of CPW.

“…Given that mineral wool waste together with glass waste mainly contains Al2O3, SiO2 and Na2O which being similar to the chemical components of regular foam glass and ceramics [18], much of studies investigated the produce of ceramics with high Al2O3 and SiO2 content raw materials like mineral wool waste and waste glass [19][20][21][22]. SiO2 is usually used to make the generation of liquid phase during the sintering process of Al2O3 ceramics and thus lower the sintering temperature.…”

To reduce the energy consumed by building part, a new method of producing foam glass at low temperature was proposed in this study. Mineral wool waste and waste glass recycled from building construction and demolition (C&D) process were used as major raw materials. In the meanwhile, calcium carbonate (CaCO3), borax (Na2B4O7•10H2O) and sodium phosphate (Na3PO4•12H2O) were added as extra additives, which played the part of foamer, fluxing agent and foam stabilizer, respectively. The effects of different content of each additives and different sintering temperature on the properties of foam glass were investigated. Bulk density, cross-section view and microstructure of the specimens were showed. The experiment results showed that the optimal content of raw materials and additives was 40 wt.% mineral wool waste, 60 wt.% waste glass, 20 wt.% borax, 1-2 wt.% calcium carbonate and 2 wt.% sodium phosphate, and its optimal sintering temperature was 800℃. The specimen sintered at this optimal condition had the most uniform foam structure and low bulk density of 0.7 g/cm 3. Finally, 2 EnergyPlus TM was used to evaluate the benefit of applying this new foam glass on the reduction on space conditioning loads, especially in relatively colder zones.

Tile production has an important place in overall ceramic production. There are different types of methods for them. Companies generally use wet route for raw materials preparation. However, dry route has been started to be used at large scale in recent years. There are some advantages and disadvantages for dry and wet route tile productions. This paper was prepared to give detail information about both methods.
