Rhombellation: a builder for multi-shell clusters

Rhombellanes are mathematical structures, proposed by us in 2017; they may appear both in periodic crystals or in finite structures. The simplest rhombellane is rbl.5 or K_2.3, the complete bipartite graph. In this paper, rhombellation operation is iteratively applied on three classes of structures: cube, tori and cubic pcu-network, respectively. The structural topological parameters are detailed.     

Evaluation of thermodynamic simulation (FactSage) for the interpretation of the presence of phases and the firing behavior of triaxial ceramics

The present work provides an evaluation of the thermodynamic calculation, using the FactSage software, which allows the study of the interaction of a system of various oxides. It started with the examination of the crystalline phases present in the raw materials indicated by the FactSage and compared with the analysis by XRD. Subsequently, the crystalline phases and the amount of liquid phase predicted by the software at different firing temperatures were analyzed. These results were compared with experimental data and records from the literature. The FactSage showed consistent results, managing to indicate the presence of the main phases in the raw materials; however, the actual and predicted secondary phases did not always coincide. The type of phase in the firing was correctly indicated, tridymite (stable phase above 867 °C), mullite and liquid phase, but their quantity in relation to the firing temperature was quite different from the experimental data.     

Synthesis of a foam ceramic based on ceramic tile polishing waste using SiC as foaming agent

Due to the large amount of ceramic tile polishing waste generated in China, the recycling of this waste residue becomes important. Herein a foam ceramic was successfully produced by using ceramic tile polishing waste as main raw material. In this research, SiC was added as the foam agent, and the foaming mechanism was also investigated. The results showed that the best dosage of SiC was 1%. Furthermore, in order to obtain a foam ceramic with better structure, the sodium phosphate was added in raw materials as foam stabilizer. The influence of this addition on the microstructure and properties of foam ceramic was investigated. It was found that the optimum additive amount of sodium phosphate is 2–3%.
