Full Description

Red lead (lead tetroxide, Pb3O4; CAS 1314-41-6) is a bright red-orange lead oxide. It is used as a pigment in lead glass, glass containers, ceramics, and paints, as a component of battery anodes and lubricant coatings, and as a chemical intermediate and catalyst.

Frequently Asked Questions

What is red lead powder used for?

Red lead (lead tetroxide, Pb3O4) is used as a bright red-orange pigment in lead glass, glass containers, ceramic glazes, and paints. It is also a component of battery anodes and lubricant coatings and serves as a chemical intermediate and catalyst.

How is red lead oxide made?

Red lead is produced by oxidizing lead monoxide (litharge, PbO) in air at elevated temperature, converting it to lead tetroxide (Pb3O4). The reagent grade is a refined, high-purity bright red-orange powder.

What industries use litharge?

Litharge (PbO) and its higher oxide red lead (Pb3O4) are used in lead-acid battery manufacture, glass and ceramics, pigments, and as catalysts and chemical intermediates. RawSource supplies the red lead (Pb3O4) reagent grade for these uses.

What is the chemical formula and CAS number for red lead?

Red lead is lead tetroxide with formula Pb3O4 and CAS number 1314-41-6. It classifies under HS code 2824.90 (red lead and orange lead) and is supplied as a reagent-grade powder.

How do I get bulk pricing and documentation for red lead reagent?

RawSource supplies the red lead reagent powder with a CoA and SDS on every order. Submit an RFQ with your purity grade, volume, and packaging requirements for a current bulk quote; consult the SDS for handling and transport classification.
