Thermal Stability and Phase Studies of LiH + BeH sub 2 System.

摘要

Phase studies (powder x-ray diffraction (XRD)) were made of isothermally annealed material using a wide angle rotating anode diffractometer. The primary compositions studied were 1:1 and 2:1 of LiH:BeH sub 2 where the 1:1 gave LiBeH sub 3 and the 2:1 gave Li sub 2 BeH sub 4 . The thermal stability studies were made up to 425/degree/C by annealing in carefully controlled atmosphere reactors. These samples are stable long enough to obtain data without evidence of reaction. 14 refs., 2 tabs. (ERA citation 14:008270)
