Lattice parameters and thermal expansion of zinc telluride and mercury selenide

Abstract

The lattice parameters of zinc telluride and mercury selenide were measured with a Unicam 19 cm high-temperature powder camera; the following equations represent the results: ZnTe, at = 6.1016 + 54.63 × 10−6t + 6.82 × 10−9t2 + 5.28 × 10−12t3; HgSe, at = 6.0854 + 28.61 × 10−6t + 4.93 × 10−9t2 + 3.74 × 10−12t3. The expressions for thermal expansion coefficients are also given.
