Microwave Synthesis of Transition Metal Nitrides

9419603 ZurLoye这项研究将探索新的低温合成路线，以制备新型氮化物材料，特别是三元氮化物。展示利用微波合成制备更多固态氮化物的可行性是本研究的目标。要研究的反应包括将二元金属氮化物(如镓、铝或硅的氮化物)与过渡金属直接结合，在较温和的合成条件下生成二元或三元过渡金属氮化物。将研究两种类型的反应：在封闭系统中进行的反应和在流动系统中进行的反应。%尽管氮化物是一类重要的工业材料，但已知的只有几百种。这项研究的重点将放在一类过渡金属氮化物上，这种材料因其坚硬而坚固，是热和电的良好导体而越来越被公认为重要的工业材料。此外，一些具有超导性，另一些具有催化性能。过渡金属氮化物在结构材料、耐腐蚀和耐刮擦涂层以及半导体工业的封装材料等领域得到了广泛的应用。***

9419603 zurLoye This research will explore new low temperature synthetic routes for the preparation of novel nitride materials, particularly ternary nitrides. Showing the plausibility of using microwave synthesis for the preparation of additional solid-state nitrides is the goal of this research. Reactions to be studied include the direct combination of a binary metal nitride, such as those of gallium, aluminum, or silicon, with a transition metal to produce a binary or ternary transition metal nitride at milder synthetic conditions. Two types of reactions will be studied: reactions carried out in closed systems; and reactions carried out in flowing systems. %%% Even though nitrides are an important class of industrial materials, only a few hundred are known to exist. The focus of this research will be on a class of transition metal nitrides that are increasingly recognized as important industrial materials because they are hard and strong, and are good conductors of heat and electricity. In addition, some exhibit superconductivity, and others have catalytic properties. Transition metal nitrides are finding utility in diverse areas such as structural materials, corrosion and scratch resistant coatings, and as packaging materials in the semiconductor industry. ***
