Thermal Expansion of Zinc Sulfide: 300?1300 K

Abstract

The thermal expansion of hot-pressed cubic polycrystalline zinc sulfide (Eastman Kodak: Irtran 2) was measured in a silica pushrod dilatometer. The coefficient of linear thermal expansion varies almost linearly from 6'9xlO- 6 K-l at 300K to lO'3xlO- 6 K-l at 1200K. The temperature variation of the Debye--Waller factor is calculated and compared with the experimental values found by Moss et al. (1980).
