A Novel Decontamination Process for Powders

SUMMARY Lehigh University has developed a purification process for magnesium aluminate spinel powder. The process has been successfully utilized to remove unwanted elements in commercial grade spinel powders. It can potentially be used for the purification of other similar materials as well. The process involves treating powders in ultra-high vacuum...

A Novel Decontamination Process for Powders

The proposed technology involves a pretreatment process to remove unwanted elements in commercial powders. The process involves treating powders in ultra-high vacuum with or without concurrent heating for extended period of time. In this process the impurities (predominantly the anionic species) are removed from the powders without any changes in the...
