A comparison of syntheses approaches towards functional polycrystalline silicate ceramics

چکیده
This study aims to shed light on processing pathways towards functional silicate ceramics, which show some promise in various emerging applications, including dielectrics and bioactive implant materials. Polycrystalline ceramics of Neso, Soro Inosilicate families were synthesised by three different techniques: (i) a co-precipitation method, (ii) modified sol-gel method (iii) standard solid-state reactions. Co-precipitated samples increased sintering densification behaviour compared methods, with diametral shrinkage values during 28.8%, 13.3% 25.0%, respectively. Well-controlled phase formation these was most readily achieved through the steric entrapment cations shorter diffusion afforded Pechini-type method. Substituting Zn2+ for Mg2+ enstatite found enhance orthoenstatite cooling, is otherwise very slow. We present guidelines design synthesis methods that consider requirements terms microstructure.

15 صفحه اولPotential and Impedance Imaging of Polycrystalline BiFeO3 Ceramics
Electrostatic-force-sensitive scanning probe microscopy (SPM) is used to investigate grain boundary behavior in polycrystalline BiFeO3 ceramics. Scanning surface potential microscopy (SSPM) of a laterally biased sample exhibits potential drops due to resistive barriers at the grain boundaries. In this technique, the tips acts as a moving voltage probe detecting local variations of potential ass...
متن کاملNanoparticles and Fabrication of Transparent Polycrystalline Yttria Ceramics
In this thesis, we report on a process to obtain yttrium oxide nanosized particles doped with ytterbium and a sintering method that leads to transparent polycrystalline ceramics. First, nano-powder of yttria was fabricated from a precursor with transient morphology, i.d. yttrium hydroxynitrate platelets that decompose into spherical yttria nano-particles during calcination. The influence of dif...
متن کاملPentacoordinate Silicon Complexes as Precursors to Silicate Glasses and Ceramics
The recent discovery that pentacoordinate alkali glycolato silicates such as monomeric MSi(OCH,CH,O),OCH,CH,OH or dimeric M,Si,(OCH,CH,O), (where M = Li, Na, K, or Cs) can be synthesized directly from SO,, ethylene glycol, and MOH suggests that these compounds may serve as useful, inexpensive precursors to alkali silicate glasses or ceramics, either by sol-gel processing or by simple pyrolysis....
