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. ***
