UM1981-31-Te:Pd

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Pd8Te3
One of many Pd-Te natural phases.

Found among heavy mineral concentrate from diamond drill core; occurs as complex polycrystalline grains, up to 60 x 100 microns in size, associated with braggite (altered), hollingworthite, laurite, moncheite, and a Pt-Cu alloy.

Synthesized phase has similar properties, but is not reported in the literature.
