The Hyperion Data Sheet, p. 6 says "row material" which I assume is a typo for "raw material" and I assume it is talking about the powder. Anyway, it says:
Sub Sieve Particle Size: 3-7 microns Bulk density: 1,8-2,7gr/cm3 Typical surface area Chemical composition (Wt%): 0,4m2/gr (BET) Preparation method: Proprietary Chemical composition Carbon: 0,07 Sulphur: 0,0001 Oxygen: 0,008 Nitrogen: 0,001 Iron: 0,001 Cobalt: <0,00002 Total other: <0,001 Nickel: Balance - Jed
