Description

Lead Sesquioxide (CAS NO 1314-27-8) is a high-purity inorganic compound, also known as lead(II,IV) oxide or red lead, valued for its distinctive chemical and physical properties. It serves as a critical intermediate and functional material in several advanced industrial processes. This product is essential for manufacturers in the ceramics, pigments, battery, and specialty glass industries seeking reliable, high-quality raw materials.

Application

• Ceramic Glazes and Frits: Acts as a flux and colorant, producing vibrant red and orange hues in specialty ceramics and glass.
• Anti-Corrosive Primers: A key component in lead-based primers (e.g., "red lead primer") for the corrosion protection of steel structures, bridges, and ships.
• Lead-Acid Battery Manufacturing: Used in the production of positive plate active material, contributing to battery performance and longevity.
• Pigment Production: Serves as a base for manufacturing durable red and orange inorganic pigments used in paints, plastics, and coatings.
• Pyrotechnics and Matches: Functions as an oxidizing agent in the formulation of certain pyrotechnic compositions and match heads.
• Specialty Glass and Optics: Imparts specific optical properties, such as increased refractive index and radiation shielding, in lead crystal and technical glass.
• Chemical Synthesis: Employed as an oxidizing agent or a precursor in various organic and inorganic synthetic processes.
