制备了不同形状的无缺陷块状氢化钛(TiHX：X=1.53~1.75)，并对其电学和热学性能进行了研究。氢化钛的电导率略低于金属钛，表现出类似金属的温度依赖性。由于氢化作用，Ti-H体系的塞贝克系数由正变负，氢化钛的塞贝克系数的绝对值保持在较低的水平，这是金属材料的典型特征。氢化物的导热系数与金属相同，但随温度升高略有增加。
Various shapes of flaw-free bulk titanium hydrides (TiHX: X=1.53–1.75) were fabricated, and its electrical and thermal properties were studied. The electrical conductivity of titanium hydride was slightly lower than that of titanium metal, and it exhibited metal-like temperature dependence. The Seebeck coefficient of the Ti–H system changed from positive to negative due to hydrogenation, and its absolute value for titanium hydride remained at a low magnitude, which is typical for metallic materials. The thermal conductivity of the hydride was the same as that of the metal and increased slightly with increasing temperature.
