Pigment Blue 71 Zirconium Vanadium Blue Zircon PB 71

 

 

FU-E561, C.I. Pigment Blue 71; C.I. 77998; Zirconium Vanadium Blue Zircon. Zirconium vanadium blue zircon , an inorganic pigment that is the reaction product of high temperature calcination in which zirconium (IV) oxide, silicon oxide, and vanadium (IV) oxide in varying amounts are homogeneously and ionically interdiffused to form a crystalline matrix of zircon. Its composition may include any one or a combination of the modifiers alkali or alkaline earth halides. C.I. Pigment Blue 71. Suitable for high gloss glaze and matte glaze, Paint, Coatings, Printing inks & Adhesives , Plastics & Rubber.

 

 

 

 

 

Zirconium Vanadium Blue Zircon PB 71 – Advantages in Vitreous Enamel

Key Advantages in Vitreous Enamel
Exceptional High-Temperature Stability
As a zircon-based pigment, it offers outstanding thermal stability, easily withstanding enamel firing temperatures (typically 750–850°C and above) without color degradation or fading.

Bright & Clean Turquoise-Blue Hue
Produces a bright, slightly greenish turquoise blue that is distinct from cobalt-based blues, providing unique aesthetic appeal and color flexibility.

Excellent Chemical & Weather Resistance
Highly inert in both acidic and alkaline environments. Exceptionally resistant to UV light and harsh weather conditions, making it ideal for outdoor architectural and sanitary applications.

Heavy-Metal-Free Composition
Contains no cobalt, lead, cadmium, or other restricted heavy metals, ensuring compliance with global environmental and safety regulations (e.g., RoHS, REACH, FDA for food-contact surfaces).

Good Compatibility & Stability in Enamel Frits
Chemically compatible with most enamel frit systems, ensuring smooth integration, strong adhesion, and a uniform glossy finish without adverse reactions during firing.
 

 

 

Zirconium Vanadium Blue Zircon PB 71 Typical Enamel Applications
Architectural enamel panels and facades

High-temperature cookware and kitchen appliances

Sanitaryware (bathtubs, sinks, tiles)

Outdoor signage and decorative enamel objects

Industrial and chemical-resistant coatings
 

 

 

 

Zirconium Vanadium Blue Zircon PB 71 Important Notes
The color can be sensitive to firing atmosphere; optimal results are achieved in oxidizing conditions.

Often more cost-effective than high-performance cobalt blues, especially when regulatory compliance is a priority.
