| Bulk commercial yttrium. Description supplied by the source: This is the form in which rare earth raw material is often distributed for bulk users--after being distilled into the dendritic form, it is then melted down by computer-controlled non-consumable electrode arc melters in vacuum/argon to main the purity (3N5). The characteristic bottom surface results from being melted only once, thoroughly, without much care towards appearance. For a given lot of rare earth (ingots like these are sold by the bucket or drum), one will be robotically selected at random and have a sample core drilled out of the top in order to provide a certified lot purity- this sample was chosen to display that particular phenomena. Also, it was a lot of fun to dig through a 30-pound pail of yttrium hemispheres.
