“…Most impurity peaks could be attributed to a previously unknown yttrium oxycarbide (Y 2 O 2 C 2 ), which is isotypic to La 2 O 2 C 2 reported by Butherus and Eick. 21,22 The weight ratio of Y 2 O 3 to Y 2 O 2 C 2 in the nanoparticles was refined to 92:8 for ethanol solvent spraying and 90:10 for acetone within the margins of error. Three remaining weak reflections must be attributed to a presently unknown compound.…”

Suspension plasma spraying was used to synthesize Y2O3 nanoparticles. The Y2O3 starting material was first dispersed in a solvent to form a suspension and then injected axially into the plume of an inductive radio frequency plasma. It was found that the as-sprayed Y2O3 particles had a size distribution from nano to micron scale and various morphological features, which varied with processing conditions as well as solvent and plasma gas type. In comparison with water, organic solvents led to a higher productivity and smaller particle size, whereas water introduced impurities such as Y2O2C2, which is isotypic to La2O2C2. Introduction of oxygen as an auxiliary plasma gas was an effective way to eliminate this impurity. In addition, complete combustion of the organic solvent and recombination of oxygen atoms above 4000 K also elevated the heat treatment degree of Y2O3. As a result, application of O2 with an organic solvent resulted in an even smaller mean particle size and narrower size distribution.

“…The small amount Y202C2 impurity that formed at high temperature is isotypic to La202C2, reported by Butherus and Eick in 1973 and 1976 respectively [102,103]. The Y202C 2 was retained at room temperature since the high quenching rate could "freeze" the high-temperature equilibrium structure.…”

I would like to take this opportunity to express my heartfelt gratitude to my supervisor, Asst. Professor Alfred Tok, for his instructive guidance and helpful support throughout the entire work. He has always shown his complete trust in me and gave me sufficient space for my own ideas and directions. His support in my research as well as concern in my personal life has helped me achieve my goals. He has been not only a good mentor and good leader, but also a good friend all this time. I am very grateful to Dr Rene Huebner for his diligent assistance on the XRD analysis of my research as well as patient instructions and precious suggestions. Also, thanks to Associate Professor Ng Heong Wah and Dr Kang Chang Wei for their important contribution to my modeling work. Thanks to Dr Martin Karl Schreyer for his kind help on my refinement work. I am grateful to my TAC group members Associate Professor Ma Jan, Asst. Professor Gan Chee Lip and Associate Professor Subodh G. Mhaisalkar for their precious comments and suggestions on my first and second year work. In addition, I thank Mr Eric Bouchard from TEKNA Plasma Systems Inc. for his generous technical support of my spraying system. Mr Samsudin Bin Sarim in Ceramics Processing Lab, NTU has provided his very kind and competent support for my experimental work for the three years, so I would like to convey my sincere appreciation to him. Other people I am grateful to are my research group members and friends Su Liap Tat, Happy, and Du Siwei for their encouragement and discussions on my research work. I would also like to thank the financial support of the School of Materials Science & Engineering and the Graduate Scholarship from Nanyang Technological University for my research work. Finally, I want to express my deepest appreciation to my wonderful parents and my beloved wife, Sha Xuena, for their unselfish love, constant encouragement and support at all times.
