Single crystals of Cu[Formula: see text]Te, Cu[Formula: see text]Zn[Formula: see text]Te and Cu[Formula: see text]Cd[Formula: see text]Te compounds were synthesized by Brijmen method and their crystal structure was studied by X-ray diffraction. The hexagonal, orthorhombic aand cubic structure phases of these compounds have been determined at room-temperature. Phase transitions at high-temperatures were observed. Lattice parameters for hexagonal, orthorhombic and cubic phases have been determined in the temperature range of [Formula: see text]–1073 K. From the temperature dependences of the lattice parameters, the coefficients of thermal expansion of the existing modifications in the main crystallographic directions were calculated.

Cu1.75−xMxTe 晶体的结构和热性能

Cu[化学式：见正文]Te、Cu[化学式：见正文]Zn[化学式：见正文]Te和Cu[化学式：见正文]Cd[化学式：见正文]Te化合物的单晶采用Brijmen法合成，通过X射线衍射研究了它们的晶体结构。这些化合物的六方、斜方和立方结构相已在室温下测定。观察到高温下的相变。已在 [公式：见正文]–1073 K 的温度范围内确定了六方相、斜方晶相和立方相的晶格参数。从晶格参数的温度依赖性来看，现有修改在主要结晶方向上的热膨胀系数进行了计算。
