Description

Zircon, Iron Coral CAS NO 68187-13-3 is a specialized inorganic pigment and ceramic colorant known for its unique coral-red to pinkish-brown hue and excellent thermal stability. This compound is valued for its ability to impart durable, fade-resistant coloration in high-temperature applications. It is primarily sought by manufacturers in the ceramics, glass, and construction materials industries seeking consistent, high-performance pigments.

Application

• Ceramic Glazes and Bodies: As a primary colorant for producing stable coral, pink, and terracotta shades in sanitaryware, tiles, and tableware.
• Glass Coloring: For tinting borosilicate glass, container glass, and specialty glassware with heat-resistant colors.
• Construction Materials: Incorporation into concrete pavers, roofing tiles, and architectural facades for permanent, weather-resistant pigmentation.
• Refractory and Abrasive Materials: Used as a component in zirconia-based refractories and grinding wheels for its structural and coloring properties.
• Artistic and Decorative Uses: In artists' pigments and for coloring decorative plaster and stucco.
• Plastic and Masterbatch: For coloring engineering plastics where high-temperature processing is required.
