Synthesis and Characterization of Erbia - Doped Yttria - Stabilized Ceria - Zirconia Based Nanoceramics

Abstract

Erbia doped yttria-stabilized ceria-zirconia based nanocrystalline ceramics were fabricated via the conversion technique from polymer to ceramic by metal acetate as preceramic hybrid polymer solutions. Samples were characterized by Scanning Electron Microscopy, Fourier Transform Infrared Spectroscopy, and X-ray Diffraction. Nanocrystallite size was evaluated via the Scherrer formula. The smallest lattice constant and crystallite size were acquired for the sample comprising Zr (74 %), Y (11 %), Ce (10 %), and Er (5 %) as the ratio of atomic weight. Scanning Electron Microscopy results indicate that increase in yttria content increased the agglomeration of the grains

Erbia - Katkılı İtriya - Stabilizeli Serya - Zirkonyum Bazlı Nanoseramiklerın Sentezi ve Karakterizasyonu

Abstract

Erbia- katkılı itriya - stabilizeli seryum-zirkonyum bazlı nanokristalin seramikler, ön seramik hibrit polimer çözeltileri olarak metal asetat ile polimerden seramiğe dönüşüm tekniği ile üretildi. Numuneler Taramalı Elektron Mikroskobu, Fourier Dönüşümlü Kızılötesi Spektroskopisi ve X-ışını Kırınımı ile karakterize edildi. Nanokristalit boyutu Scherrer formülü ile değerlendirildi. En küçük kafes sabiti ve kristalit boyutu, atom ağırlığına oran olarak Zr (%74), Y (%11), Ce (%10) ve Er (%5) içeren numune için elde edildi. Taramalı Elektron Mikroskobu sonuçları itriya içeriğindeki artışın taneciklerin aglomerasyonunu artırdığını göstermektedir.
