Lead oxide is a general term & can be used to describe either –

• Lead Monoxide – PbO – Litharge
• Lead Tetroxide – Pb3o4 – Red Lead – Brilliant Orange Red Pigment.
• Black or Gray Oxide – 70% PbO + 30% Metallic Lead

Red Lead is used in

• Ferrous Metal Protective Paints
• Stationary / Traction / Tubular Plate Batteries
• Crystal Glass
• Television Tubes
• Glazes

Red lead forms through an oxidation process when the raw material (lead oxide from ball mill) is heated to around 450^oC in a furnace. In the oxidation process, the controlling has to be done of –

• Lead Oxide
• Oxygen
• Temperature
• Time

After the desired % of Red Lead has been reached, it is discharged & ground in a low impact hammer mill to adjust for particle size, distribution, acid adsorption, apparent density etc.

Process: -
A vertical agitator is used for constant mixing of powder inside the furnace. A vertical shaft supports & turns agitator arms to stir the batch lying on top of furnace.
