Palladium powders of the PP series are intended for the manufacture of pastes for thick-film conductors, electrodes of monolithic ceramic capacitors, and for other purposes.

There are three grades of PP series powders: PP-1, PP-2, and PP-3. Some technical characteristics:

Appearance: PP-1 — from dark gray to black, PP-2 and PP-3 — gray.
Bulk density: PP-1 — 0.3–0.7 g/cm³, PP-2 — 0.4–1.0 g/cm³, PP-3 — 0.8–1.3 g/cm³.
Specific surface area: PP-1 — 3–6 m²/g, PP-2 — 2–5 m²/g.
Palladium content: PP-1 — not less than 98%, PP-2 and PP-3 — not less than 98%.
The TU number according to which PP series powders are manufactured is EPO.035.004TU.
