Cu₇Te₄ powders were fabricated by both wet chemistry method and hydrothermal method. The phase structure and microstructure of Cu₇Te₄ powders were analyzed by X-ray diffraction (XRD) and scanning electronic microscope (SEM). The XRD results showed that no secondary phases were detected in as prepared Cu₇S₄ powders. The SEM observation showed that all samples are composed by same oriented plate-like grains with similar sizes about diameter 1–3 μm and thickness 0.2–0.5 μm. The Cu₇Te₄ powders prepared by wet chemistry were then densified to bulk materials. The thermoelectric properties of Cu₇Te₄ bulk material was measured, showing that the highest ZT value of 0.05 was obtained at 723 K.

采用湿化学法和水热法制备了Cu ₇ Te ₄粉末。通过X射线衍射（XRD）和扫描电子显微镜（SEM）分析了Cu ₇ Te ₄粉末的相结构和微观结构。XRD结果表明，在制备的Cu ₇ S ₄粉末中未检测到第二相。扫描电镜观察结果表明，所有样品均由相同取向的板状晶粒组成，晶粒大小相似，直径约1–3μm，厚度约0.2–0.5μm。然后将通过湿化学制备的Cu ₇ Te ₄粉末致密化为块状材料。Cu ₇ Te ₄的热电性质 测量散装材料，显示在723 K时获得最高的ZT值为0.05。
