Glass ceramics, lead sodium niobate silicate (PNNS), barium sodium niobate silicate (BNNS) and barium titanate silicate (BTS), allow the development of dielectrics with various permittivity values ranging from 20 to 700. Glasses were formed by melt-rolling the respective constituents which were then crystallized by reheating the glass at higher temperatures. Heat treatment schedules were formulated based on DTA results. A spectrum of crystalline phases, ranging from perovskites, tungsten bronzes and pyrochlores to fresnoites, were generated within the various glass matrices. Disadvantages, such as difficult glass formability, less control over crystallization due to multiphase formation etc., associated with high permittivity PNNS and BNNS glass ceramics served as the motivating factor for exploring low permittivity glass ceramics. BTS glass ceramics exhibit excellent stability in permittivity, high resistivity and low loss over the measured range of temperature. Thin samples with pristine surfaces are required for achieving high breakdown strength values. Investigation of the crystallization kinetics of BTS glass would provide further insight into exploring glass nano-composites, analogous to polymer nano-composites.","PeriodicalId":228914,"journal":{"name":"2008 17th IEEE International Symposium on the Applications of Ferroelectrics","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114761564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Samples of piezocomposites with the volume fraction of components 0¿100% for different PZT compositions were fabricated and measured. A line of chemically, thermally, and technologically compatible PZT matrix and filling compositions were chosen. Different types of PZT type piezoceramics powders and pre-sintered piezoceramic granules were used as matrix and filling components respectively. The size and shape of the filling particles were chosen as a compromise between maximal scattering and minimal interfacial area to minimize chemical interaction between two composite phases. Special pressing and firing regimes were used for formation of microporous piezoceramic matrix. Sintering of the composites was carried out at special thermal profiles preventing cracking because of shrinkage and thermal expansion of composite components. Complex sets of elastic, dielectric, and piezoelectric parameters of piezocomposites were determined by ultrasonic and impedance spectroscopy method using piezoelectric resonance analysis (PRAP) software. Microstructure of polished, chemically etched, and chipped surfaces of piezocomposite samples was observed with optical and scanning electron microscopes. New PZT/PZT ceramic piezocomposites are characterized by a unique spectrum of the electrophysical properties unachievable for standard PZT ceramic compositions and fabrication methods and can be useful for wide-band ultrasonic transducer applications.","PeriodicalId":228914,"journal":{"name":"2008 17th IEEE International Symposium on the Applications of Ferroelectrics","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126402310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nonlinear dielectric response was measured in the parallel plate capacitor configuration, whereby the low frequency linear permittivity ( ¿33 ), and the higher order permittivities ( ¿3333, ¿333333 ) at 298 K were obtained as å33PMN-PT = 2.1x10¿7 and ¿33BTS = 4.1x10¿8 (F/m), ¿3333PMN-PT= ¿4.9x10¿20 and ¿333333BTS = 9.85x10¿34 (F3m/C2), and ¿333333PMT-PT = 7.6x10¿33 and ¿3333BTS = ¿7.3x10¿21 (F5m3/C4). By using a self-consistent thermodynamic theory in conjunction with the experimental data, we compute the E3 dependence of electrostatic energy ¿G , the field-induced polarization response P3 , the thermodynamic tunability ¿2P3/¿E32 , and prove that electrostatic free energy has to be expanded at least up to the sixth order in electric field define the critical field |E3*| at which maximum tunability is attained. We also show that |E3*| is a function on |¿3333|/¿333333 only. Consequently, we find |E3*|PMT-PT = 8.6x105 V/m and |E3*|BTS =8.0x105 V/m. We compute the engineering tunabilities as ¿PMN-PT =65% and ¿BTS =55%, and then define a normalized tunability ¿ to take into account the |E3*| parameter. Thereof, we determine |¿|PMT-PT = 8.1x10¿5 and |¿|BTS =6.4x10¿5 %/Vm¿1. Our results reveal that |E3*|BTS >|E3*|PMNPT although ¿BTS < ¿PMNPT, unequivocally showing the need for defining a critical field parameter in evaluating the nonlinear dielectric response and tunability in particular, and in nonlinear dielectrics in general. The results also indicate that the nonlinear dielectric properties of PMN-PT are an order of magnitude higher than that of BTS, which we discuss in the context of structure-property relations of relaxors.","PeriodicalId":228914,"journal":{"name":"2008 17th IEEE International Symposium on the Applications of Ferroelectrics","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123693209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
