Abstract

Zirconia is widely used ceramic powders as a biomaterial in medical applications due to its similarity with tooth color, good mechanical and bioinert properties. Its high temperature forms can be fully or partially stabilized by the addition of oxides such as MgO, CaO and Y 2 O 3 . Recently, yttria stabilized zirconia has been mostly studied because of its lots of advantages. In this study, 3% mol and 8% mol yttria stabilized zirconia powders have been synthesized using a simple sol-gel process. ZrO(NO 3 ) 2 .xH 2 O and Y(NO 3 ) 3 .6H 2 O was dissolved in ethylene glycol and pure water, respectively and mixed together. After mixing pH was adjusted to 3.5 using HNO 3 . Final suspension was stirred until it becomes homogenized. Homogeneous mixture dried at 120°C and then sintered at 1200°C. Crystallite sizes and mineralogical composition were determined by XRD. Surface area was measured by BET method and particle size was calculated. Density of powders was measured by ultrapicnometer. Also, morphological structure was examined by SEM. Tetragonal ZrO 2 and tetragonal ZrO 2 -Y 2 O 3 phases were observed. Current studies showed that YSZ powder can be effectively synthesis with the present method.

Özet

Zirkonya, tıbbi uygulamalarda, diş rengine benzerliği, iyi mekanik ve biyoinert özellikleri nedeniyle yaygın olarak kullanılan seramik tozlarıdır. Yüksek sıcaklık formları MgO, CaO ve Y 2 O 3 gibi oksitlerin eklenmesi ile tamamen veya kısmen dengelenebilir. Son zamanlarda, itriya stabilize zirkonya çoğunlukla avantajları nedeniyle incelenmiştir. Bu çalışmada, basit bir sol-jel işlemi kullanılarak %3 mol ve %8 mol itriya stabilize zirkonya tozları sentezlenmiştir. ZrO(NO 3 ) 2 .xH 2 O ve Y(NO 3 ) 3 .6H 2 O sırası ile etilen glikol ve saf su içerisinde çözündürüldü ve karıştırıldı. Karıştırmanın ardından pH, HNO 3 ile 3.5'e ayarlandı. Elde edilen süspansiyon homojen hale gelinceye kadar karıştırıldı. Homojen karışım, 120°C'de kurutuldu ve daha sonra 1200°C'de sinterlendi. Elde edilen tozların kristal boyutları ve mineralojik kompozisyon XRD ile belirlenmiştir. Yüzey alanı BET metodu ile ölçülmüş ve partikül büyüklüğü hesaplanmıştır. Tozların yoğunluğu ise ultrapiknometre ile ölçülmüştür. Ayrıca SEM ile morfolojik yapı incelenmiştir. Tetragonal ZrO 2 ve tetragonal ZrO 2 -Y 2 O 3 fazları gözlendi. Mevcut çalışmalar, YSZ tozunun bu yöntemle etkili bir şekilde sentezlenebileceğini göstermektedir.
