In the granulation process, 10 % isopropanol is added into ethanol to increase the viscosity. More than that, the green body of the ceramic is placed into the isostatic press and pressed at 200 MPa for 3 min again after being kept in the muffle furnace at 120 °C for 1 h. The modified solid-state reaction method further improves the sintering property of the Na2WO4 ceramic, which increases the dielectric property of the ceramic sample greatly. Besides, the granulation problem, the bubble problem and the problem in demoulding process are solved. The substitution of ethanol and isopropanol for polyvinyl ethanol (PVA) completely avoids the residue of PVA in the ceramic sample and increases the fluidity of the ceramic particles in the granulation process. As a result, the Na2WO4 ceramic can be sintered well at 560 °C with a relative permittivity of 5.82, Q × f value of 131300 GHz and a temperature coefficient of resonant frequency (TCF) value of −56.2 ppm/°C in this work. The modified solid-state reaction method is a good substitute for the conventional solid-state method.","PeriodicalId":17246,"journal":{"name":"Journal of the Ceramic Society of Japan","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135161390","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}

The first calculation used an empirical PF mobility [Lexp = A(kBTΔT/6π2λ3η)B], which was determined from experimental crystal growth rates (vexp). The calculation results for various binary borides such as Li2O–2B2O3, Na2O–2B2O3, Na2O–4B2O3, K2O–4B2O3, BaO–2B2O3, and PbO–2B2O3, agreed well with the experimental vexp below their melting points. Furthermore, the A and B values of the Lexp for the borides depended on diffusivity and cation molar mass, including that it is important for cation transfers during crystallization. The second calculation solved the PF equation using versatile PF mobility (L′ ∼ rD/κ2), in which an interfacial process (r) was included. The calculation results agreed well with the first calculation results and the experimental vexp, except for Li2O–2B2O3. In Li2O–2B2O3, the interfacial process strongly affected the crystal growth rates because of the strong nonlinear phenomenon. For diffusive ceramics such as Li2O–2B2O3, we should use the empirical Lexp. However, the versatile PF equation, which includes the interfacial process (L′) can predict the vexp of many borides.","PeriodicalId":17246,"journal":{"name":"Journal of the Ceramic Society of Japan","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135372807","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 paper, we revisit a proposed method (PM) that was thought to be ineffective in determining the stable GB structures based on sampling non-identical terminating crystal planes of the two adjoining crystals forming the GB. In contrast to the previous conclusion, we found that the PM is effective regarding both the reproducibility of stable structures and calculation cost. This method could determine the most stable GB structures and energies of not only elemental materials of face-centered-cubic and body-centered-cubic metals, including Cu and Mo, but also a binary ceramic material, MgO. We show that the PM can greatly reduce the number of necessary candidate structures calculated to determine the stable GB structures compared with other brute-force methods sampling the rigid body translation between the two adjoining crystals. We demonstrated that sampling GB structures made of non-identical termination combinations is a useful and effective method to determine the stable GB structures of various materials.","PeriodicalId":17246,"journal":{"name":"Journal of the Ceramic Society of Japan","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135372795","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}

Compositing different materials is widely performed in developing multifunctional materials. However, only a few studies have investigated sulfide electrolytes due to the concern of lowering ionic conductivity. In this study, composite electrolytes comprising Li10GeP2S12 (LGPS)-type electrolytes and nanosized Al2O3 are fabricated by a solid-state reaction. Al2O3 particles are mainly located in the voids between LGPS particles, whereas very limited oxygen content is substituted for sulfur in the LGPS structure. LGPS–Al2O3 composites exhibit ionic conductivities of ∼5 mS cm−1 without significant changes by compositing Al2O3. LGPS–Al2O3 composites are softer and have higher atmospheric stability than uncomposed LGPS. All solid-state cells that use air-exposed LGPS–Al2O3 as a separator layer exhibit an improved cycle retention compared with that using air-exposed LGPS. These results demonstrate that electrolyte compositing is an effective means of improving other properties while maintaining high lithium ionic conductivity.","PeriodicalId":17246,"journal":{"name":"Journal of the Ceramic Society of Japan","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135372801","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}
