    • Abstract


      The temperature variation of the lattice parameter of CsPbCl3 in the cubic phase has been studied by x-ray method, from a determination of the precision lattice parameter at various temperatures, ranging from 50°C to 400°C. The coefficient of thermal expansion of CsPbCl3 can be expressed by the quadratic equation,αT = 21.6 × 10−6 + 2.44 × 10−9T + 5.90 × 10−11T2.
