Studies on Influencing Factors of Ammonium Rhenate Recovery from Waste Superalloy
Source abstract
Abstract
The influencing factors of ammonia content and centrifugal speed on ammonium rhenate recovery from waste superalloy were systematically analyzed. It was found that proper ammonia content and centrifugal speed could promote crystal growth and a higher purity of ammonium rhenate was obtained. Moreover, the XRD patterns showed that excessive ammonia content and inappropriate centrifugal speed restrained the growth of (101) crystal plane and (112) crystal plane, which caused the crystal structural regularity and relative crystallinity to attenuate. The microscopic morphology and purity of the crystal also changed.
