Description

Obtaining

The raw material for litharge is lead.

Litharge is a technical lead oxide.

Litharge is produced in the following classification targeting different usage:

Г-1 — for the orange lead crown, lead crystal, crystal glass and electroceramics;
Г-2 — for the yellow lead and lead-molybdate crown, dryers, stabilizers, PVC reinforcement and rubber products;
Г-3 — for batteries and electric carbonic products;
Г-4 — for rubber;
Г-6 — for diode glass, lead crystal and crystal glass.

Brand Г-1-Г-4 — yellow powder of different tone, Г-6 — granules of reddish-brown color.

Litharge by impact on the body is a substance of Class 1 dangerous.

Г-1, Г-2, Г-3 and Г-4 — 6 months

Г-6 — 12 months from a date of manufacturing.
