“…Salah satu contoh material keramik yang dapat dijadikan sebagai bahan kajian adalah ZrO 2 [13][14][15]. Bahan ini sering digunakan sebagai material solid oxide fuel cell (SOFC) [16][17][18], penggunaan dalam bidang medis [19,20], bahan dielektrik [7,21], proteksi material dari korosi dan oksidasi logam [22][23][24] serta dapat digunakan sebagai matriks kolom generator radioisotop [25].…”

ZrO2 merupakan bahan keramik yang memiliki banyak struktur (Polimorpi). Struktur yang dimiliki oleh ZrO2 terdiri dari struktur monoklinik yang stabil pada temperatur ruang, tetragonal dan kubik. Metode penelitian pada penulisan jurnal ini menggunakan teknik review dari beberapa peneliti yang telah melakukan kajian secara intensif dengan berbagai variasi metode yang telah dilakukan. Selain dari itu, penyusunan jurnal ini dilengkapi dengan penggunaan software Vesta yang terintegrasi dengan data-data kristalografi yang tersedia pada laman crystallography.net/cod/ sehigga dapat memberikan simulasi atas pemberian dopan yang diberikan pada ZrO2. Berdasarkan kajian yang telah dilakukan, penambahan variasi dopan yang diberikan pada ZrO2 mengakibatkan ZrO2 kubik dan tetragonal stabil pada temperatur ruang dan terjadi perubahan nilai konduktivitas listrik akibat adanya kehadiran vakansi oksigen yang terbentuk dari adanya pemberian dopan yang diberkan. Perubahan nilai konduktivitas listrik tergantung dari jenis dan konsentrasi dopan yang diberikan.

“…Solid oxide fuel cells (SOFCs) stand out as efficient and low‐polluting sources of electrical energy. In these electrochemical conversion devices, electricity is generated by a redox chemical reaction of the fuel (H 2 , CH 4 , or CO) with O 2 acting as an oxidizer 1,2 . SOFCs consist of two porous electrodes (a cathode and an anode) and an electrolyte (an oxygen‐ion conducting ceramic).…”

Ceria, pure or doped, is an important electrolyte material in solid oxide fuel cells, catalysts, and plutonium surrogates. Even though ceria is a widely studied material, its coprecipitation with the most common doping element, gadolinium, remains mostly overlooked. Here, we present a comprehensive study of gadolinium–cerium oxalates prepared by coprecipitation of gadolinium (III) and cerium (III) salts by oxalic acid under different reaction conditions and element ratios. For this purpose, we assessed the effects of basic precipitation conditions on the final oxalate size, shape, and conversion into the corresponding oxides. The results showed that coprecipitation with oxalic acid yields and ideal solid solution, which translates into the oxides. This low‐cost and straightforward synthetic route provides then high‐quality solid solutions of Ge–Gd in the oxide lattice. Thus, this approach has a high industrialization potential, with significant advantages over hydrolysis or hydrothermal techniques.

“…Stabilized zirconia (ZrO 2 ) ceramics possess excellent properties, such as high chemical stability and strong thermal shock resistance, as well as biocompatibility, and they can be used in a variety of applications, including structural components, damage/corrosionresistant coatings, oxygen sensors and dental implantation [1][2][3]. In addition, high corrosion resistance, high ionic conductivity and low thermal conductivity make these ceramics attractive for applications as electrolyte membrane and as components in composite cathodes for solid oxide fuel cells (SOFCs) [4,5].…”

Annealing-Induced Off-Stoichiometric and Structural Alterations in Ca2+- and Y3+-Stabilized Zirconia Ceramics

In the current study, high-temperature stability was investigated in two types of zirconia ceramics stabilized with two different additives, namely, calcia and yttria. The evolutions of structure and oxygen-vacancy-related defects upon annealing in air were investigated as a function of temperature by combining X-ray diffractometry with Raman, X-ray photoelectron and cathodoluminescence spectroscopies. We systematically characterized variations in the concentration of oxygen vacancies and hydroxyl groups during thermal treatments and linked them to structural alterations and polymorphic transformation. With this approach, we clarified how the combined effects of different dopants and temperature impacted on structural development and on the thermal stability of the oxygen-vacancy-related defect complex.
