The characteristics of this compound have been determined using X-ray powder diffraction, morphological, Raman and complex impedance spectroscopy. While X-ray powder diffraction revealed that RbYP<sub>2</sub>O<sub>7</sub> compound crystallizes in the monoclinic system (P2<sub>1</sub>/c space group), the SEM mapping demonstrated that the particles have the shape of squares of different sizes and demonstrate that the mean crystalline size of the specimen is 1.75 μm. The complex impedance spectra analysis indicated that the electrical features of the compound are largely dependent on temperature and frequency. Two semi circles are detectable in the Nyquist plots of the complex impedance spectra, suggesting the contribution of the effects of the grain and grain boundary. Non-Debye type relaxation mechanism coupled with negative temperature coefficient of resistance (NTCR) behaviour was indicated by temperature dependent impedance spectroscopy. Additionally, the AC conductivity frequency dependence was interpreted in terms of Jonscher’s law, whereas DC conductivity promotes the polaron assisted hopping in RbYP<sub>2</sub>O<sub>7</sub> composition having activation energies of the grain σ<sub>g</sub> and grain boundary are Ea<sub>g</sub>= 0.81 eV and Ea<sub>gb</sub> = 1.21 eV, respectively. The power law exponent (s) yielded that the correlated barrier hopping (CBH) model corresponds to the dominant transport process in this material. Furthermore, the multiple relaxation process was revealed by the modulus spectroscopy dominated by the mixed Rb<sup>+</sup> cation motion within the investigated material structure.</p></div>","PeriodicalId":673,"journal":{"name":"Journal of the Australian Ceramic Society","volume":"61 3","pages":"1101 - 1112"},"PeriodicalIF":2.1,"publicationDate":"2025-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145161613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, a cautionary note on the inadvertent use of split-plot designs was presented to understand the processing of mullite-based ceramics from kaolin waste. Samples were obtained by solid-state reactive sintering of kaolin waste following a 2<sup>2</sup> × 2 full factorial split-plot design. The influence of firing temperature, time and applied pressing pressure on the physical properties was evaluated. The structural and microstructural analyses of fired samples were evaluated by X-ray diffractometry (XRD) and field emission scanning electron microscopy (FESEM). Kaolin waste processed ceramics at 1400 ºC consist of elongated mullite crystals uniformly embedded into a glassy phase and minor amounts of quartz.

The higher applied pressing pressure leads to lower open porosity.
