Ternary Nitrides from Inorganic and Organometallic Molecular Precursors

一个联合计划，以合成和表征新的三元稀土过渡金属氮化材料将实施。氮化物是研究最少的正价固体，它们的合成是复杂的，因为它们的形成自由能相对较低，许多的难熔性和其他的低分解温度。分子前驱体将用于在低温下合成三元氮化物，从而避免了不使用高温的扩散问题，并避免了形成自由能低的相的分解。这两位pi为这个问题带来了互补的技能：DiSalvo是固态化学家，Wolczanski是无机化学家。两位PI都不能单独完成这个项目，但他们一起拥有所有的实验设备和方法背景，可以在化学部和材料研究部共同资助的MS&amp；P资助下利用这个机会。

A joint program to synthesize and characterize novel ternary rare earth-transition metal-nitride materials will be implemented. Nitrides are the least studied normal valence solids, and their synthesis is complicated by their relatively low free energy of formation, the refractory nature of many and the low decomposition temperatures of others. Molecular precursors will be used to synthesize ternary nitrides at low temperatures, thereby circumventing diffusion problems without the use of high temperatures and avoiding decomposition of phases with low free energies of formation. The two PIs bring complementary skills to the problem: DiSalvo is a solid state chemist and Wolczanski is an inorganic chemist. Neither PI could carry out the project alone, but together they have all the experimental apparatus and methodological background to exploit this opportunity under an MS&P grant jointly funded by the Chemistry Division and the Division of Materials Research.
