Fabrication and Characterization of Mullite Reinforced Y2O3 Added ZrO2 Ceramics

Abstract

Mullite (3Al2O3.2SiO2) and 3 mol% yttria added zirconia (3 mol% Y2O3 - 97 mol% ZrO2) ceramic powders were synthesized by conventional ceramic processing route. All mixtures were prepared by mechanical alloying method in acetone environment with zirconia ball mill. Mullite and yttria added zirconia ceramic powders were synthesized by reaction sintering in air at 1600oC for 3h and 1300oC for 2h, respectively. The ceramic phases formed were made ready to form ceramic - ceramic composites by crushing, grinding and sieving processes. Then, 0 and 10% by weight mullite added yttria doped zirconia mixtures were prepared by powder metallurgy method. After drying, the powders were compacted by uniaxial pressing. The green compacts were sintered at 1500-1600oC for 1-5 h in air conditions in a high temperature furnace. Then, microstructure (SEM), phase analysis (XRD), mechanical (hardness, 3-point bending and wear) and physical properties (%shrinkage, water absorption, porosity and density) tests were performed on the composites. In this study, whether there is a phase change in the ZrO2-Y2O3 mixture at high sintering temperatures and the effect of mullite additive on the properties of this mixture was investigated. The data obtained were presented in graphs and tables and their comments were made.

Mullit Takviyeli Y2O3 Katkılı ZrO2 Seramiklerinin İmalatı ve Karakterizasyonu

Abstract

Bu çalışmada, mullit (3Al2O3.2SiO2) ve %3 mol itriya katkılı zirkonya (%3 mol Y2O3 - %97 mol ZrO2) seramik tozları geleneksel seramik üretim yöntemi ile sentezlenmiştir. Tüm karışımlar, zirkonya bilyalı değirmende aseton ortamında mekanik alaşımlama yöntemiyle hazırlanmıştır. Mullit ve itriya katkılı zirkonya seramik tozları sırasıyla 1600 oC'de 3 saat ve 1300 oC'de 2 saat sentezlenmiştir. Seramik fazlar kırma, öğütme ve eleme işlemleri ile seramik - seramik kompozitleri oluşturmaya hazır hale getirilmiştir. Daha sonra ağırlıkça %0 ve %10 mullit takviyeli itriya katkılı zirkonya karışımları toz metalurjisi yöntemiyle hazırlanmıştır. Kurutulduktan sonra, tozlar tek eksenli presleme ile sıkıştırılmıştır. Devamında, yüksek sıcaklıklı bir fırında hava koşullarında 1500-1600 oC'de 1-5 saat sinterlenmiştir. Daha sonra kompozitler üzerinde mikroyapı (SEM), faz analizi (XRD), mekanik (sertlik, 3 nokta eğme ve aşınma) ve fiziksel özellikler (% küçülme, su emme, gözeneklilik ve yoğunluk) testleri yapılmıştır. Bu çalışmada, yüksek sinterleme sıcaklıklarında ZrO2 - Y2O3 karışımında faz değişimi olup olmadığı ve mullit katkı maddesinin bu karışımın özelliklerine etkisi araştırılmıştır. Elde edilen veriler grafik ve tablolar halinde sunulmuş ve yorumları yapılmıştır.
