However, the synthesis is rarely the prime focus in materials science, which usually describe properties and characterizations of said materials. Consequently, synthesis protocols are often given too little attention in the literature and hence poorly described. For scientists starting in the field, it becomes confusing to make the right choice of synthesis route and conditions to successfully prepare what will be the base of their research, which is a pure, single phase, complex oxide powder. With this tutorial article, we are giving basic knowledge on the underlying chemistry of oxide synthesis, and simple explanations on what motivates the need of various synthesis routes. Then, four main synthesis routes are described, namely the solid state reaction route, the Pechini route, the combustion route, and the precipitation route. For each routes, the approach is described, and the relevant parameters to be considered are developed. Finally, a step by step general protocol for each route is proposed, which can serve as a solid foundation for unexperienced researchers to become more confident when approaching metal oxide synthesis.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":625,"journal":{"name":"Journal of Electroceramics","volume":"52 1","pages":"10 - 28"},"PeriodicalIF":1.7,"publicationDate":"2023-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138515963","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}

Due to their electronic conduction properties, both LaNiO<sub>3</sub> perovskites, commonly used as a cathode, and LaCrO<sub>3</sub> perovskites, commonly used as interconnectors, can also be developed to be used as an anode.

Phases with a perovskite-like structure were obtained via calcination at 900 °C. For the sintered samples, it was observed that an increase in the amount of Cr led to an increase in porosity. The compositions with x = 0.7 and x = 0.5 sintered at 1300 and 1400 °C remained single-phase after sintering, while the composition x = 0.3 sintered at 1500 °C and the composition x = 0.0 sintered at 1250 °C decomposed into secondary phases. Concerning electrical properties, the activation energy values obtained were consistent with electronic conductivity, 0.03 eV, indicating p-type conduction in an oxidizing atmosphere.</p></div>","PeriodicalId":625,"journal":{"name":"Journal of Electroceramics","volume":"51 4","pages":"281 - 291"},"PeriodicalIF":1.7,"publicationDate":"2023-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135855290","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 thick film has great technological importance as its thickness lies between the thin film and bulk material. The application, such as sensors and actuators, require a thickness that is not less than thin film or not more than bulk to be sufficiently powerful and sensitive. While the thick film is exposed to a temperature higher than room temperature, the piezoelectricity and elastic properties should not be degraded. Thus researchers have been investigating high-temperature thick films for the past decade. This review focuses on the detailed study of high-temperature piezoelectric thick films of lead-based and lead-free based materials and their composites, highlighting fabrication methods. Other important areas, such as substrates for thick film properties achieved and targeted applications, are also discussed.

The characteristics of termination MLCC made by direct nickel plating are characterized. Besides, Ni termination of MLCCs with high capacitance made by electroplating is shown to perfectly bond the electrodes to a nearly uniform surface with high adhesive strength. The inner and outer electrodes are made of the same nickel and the ohmic contact is very well shown, corresponding to excellent dielectric properties. The novel Ni termination of MLCCs with high capacitance made by electroplating is integrated with an inner Ni electrode at a low temperature process and shows the prefect performance of termination including an extreme low internal stress and much denser void free termination. This is completely different from the existing Cu termination connected with ceramic brick done by dipping at high temperature curing in a nitrogen atmosphere. Model analysis of electric field distribution and charge transport of electrochemical analysis were also performed for a better understanding of the electrodeposition process to make an Ni termination of MLCCs with high capacitance. </p></div>","PeriodicalId":625,"journal":{"name":"Journal of Electroceramics","volume":"51 4","pages":"258 - 268"},"PeriodicalIF":1.7,"publicationDate":"2023-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135153550","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}
