Ti3SiC2 belongs to a large group of ternary carbides that exhibit an unique combination of high temperature ceramic properties, with the electrical and thermal conductivity of metals. A great number of potential applications have been identified, but are currently limited by residual intermediate compounds, that degrade the properties. This project will use crystal structure similarities between TiCx and Ti3SiC2 to engineer a crystalline precursor, Ti3C2, which circumvents intermediate compound formation. This innovative methodology will also reduce the cost and time of fabrication. Advanced in-situ neutron diffraction techniques will be used to quantify the synthesis kinetics and optimize the method.

Ti3SiC2属于一大类三元碳化物，具有独特的高温陶瓷性能和金属的导电性和导热性。已经确定了大量的潜在应用，但目前受到残留中间体化合物的限制，这些化合物降低了性能。该项目将利用TiCx和Ti3SiC2之间的晶体结构相似性来设计一种晶体前体Ti3C2，从而避免中间化合物的形成。这种创新的方法还将降低制造成本和时间。先进的原位中子衍射技术将用于量化合成动力学和优化方法。
