Description

Lead Antimonate is an inorganic pigment and ceramic compound known for its distinctive yellow-orange color and high-temperature stability. This material is valued for its ability to impart durable, vibrant coloration in demanding industrial applications where heat and chemical resistance are critical. It is primarily utilized by manufacturers in the ceramics, plastics, and specialty glass industries seeking consistent, high-performance pigments.

Application

• Ceramic Glazes and Frits: A key pigment for producing bright yellow, orange, and Naples yellow hues in sanitaryware, tiles, and art pottery.
• Plastics and Masterbatch Coloring: Used as a heat-stable pigment for engineering plastics and polymers processed at elevated temperatures.
• Specialty Glass and Enamels: Imparts coloration to borosilicate glass, decorative enamels, and vitreous coatings.
• High-Temperature Paints and Coatings: Serves as a corrosion-resistant pigment in coatings for industrial equipment and automotive components.
• Electronic Ceramics: Employed in certain dielectric and piezoelectric ceramic formulations.
• Historical Artwork Restoration: Used as an authentic pigment for the conservation and replication of historical painted artworks and ceramics.
