Herein, we have reported synthesis of CaCu3Ti4O12@CoFe2O4 particles through the chemical co-precipitation route. CaCu3Ti4O12@CoFe2O4 particles consist of CaCu3Ti4O12 (~ 200 nm) as a core and CoFe2O4 as a shell of 2.5 nm. The prepared composites are characterized with appropriate characterization tools. The morphological results confirm the proper formation of core shell structure where CaCu3Ti4O12 and CoFe2O4 act as a core and shell, respectively. The greater CCTO content composites exhibited promising relative permittivity of 8.2 × 103 at 700 °C sintering temperature (8 h) at frequency 40 to 8 MHz. When CaCu3Ti4O12@CoFe2O4 undergoes heat treatment, it leads to the removal of oxalic acid. However, a weight loss of 8.3% is obtained for CCTO-coated composites that is quite low as compared to ~ 11% weight loss obtained in pristine CFO. The removal of organic groups significantly contributed to the increase in dielectric properties. These results imply that the development of CaCu3Ti4O12@CoFe2O4 core shell structure paves the wave for high-performance devices.</div>","PeriodicalId":673,"journal":{"name":"Journal of the Australian Ceramic Society","volume":"60 2","pages":"343 - 354"},"PeriodicalIF":1.8,"publicationDate":"2024-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139764235","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}

This property is a complicated phenomenon that makes it challenging to study. In 1935, the piezoelectric properties of potassium-dehydrogenated phosphate, the first famous piezoelectric material, were determined. Study about these properties of materials was developed by USA, Russia, and Japan during the Second World War, resulting in some piezoelectric materials such as barium titanate (BT) and lead zirconate titanate (PZT) in 1940 and 1950, respectively. Pure and doped PZT families have been widely studied in ceramics and nanostructured forms to enhance their piezoelectric properties. Because of the lead, the PZT materials are harmful to the environment. Therefore, it has been tried to replace it with suitable lead-free materials for practical purposes. The first lead-free piezoelectric material investigated in this respect is BT. However, the piezoelectric properties of BT are not as good as PZT, so a new generation of lead-free piezoelectric materials has been developed. These new lead-free piezoelectric materials are divided into two categories: (1) the lead-free piezoelectric material based on BNT (bismuth niobium titanate) and (2) the lead-free piezoelectric material based on KNN (potassium sodium niobite). The most significant advantage of these materials is that they are environmentally friendly, but their piezoelectric properties are less than PZT. In this chapter review, lead-based and lead-free piezoelectric materials such as PZT, BT, BZT, KNN, BNT, and ZnO are studied. The synthesized methods of piezoelectric materials in ceramic and nanostructure forms are presented. The applications of piezoelectric ceramics and nanostructures are discussed.</div>","PeriodicalId":673,"journal":{"name":"Journal of the Australian Ceramic Society","volume":"60 3","pages":"723 - 753"},"PeriodicalIF":1.8,"publicationDate":"2024-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139583356","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}
