About Edmund Storms pressed powder, did someone ask for the size of the powder ? The process of production ?
Claytor describes a process, precipitation, maybe was it the same?Quote
The palladium powder was obtained from Englehard and formed by precipitation from an aqueous solution
of Pd(NH3)4Cl2 using reagent quality chemicals. This process results in an powder composed of small (0.3 to 0.5µm) spheres that form chains or agglomerates up to 30 µm in dia.
