Composite Zircon Powder
Product Features & Applications
Composite zircon powder is manufactured through the scientific blending of multiple high-purity zircon-based raw materials. It is produced via an integrated process of mixing, homogenization, and ultra-fine grinding.
The product delivers balanced overall performance, combining high opacity, high refractoriness, strong chemical stability, and excellent cost-effectiveness. It has a well-optimized particle size distribution, broad sintering adaptability, and is not easily affected by firing atmospheres.
Our Composite Zircon Powder is widely used in general architectural ceramics, sanitary ceramic body and glaze materials, refractory castables, industrial kiln fillers, and mid-to-low-end ceramic opacifying applications for bulk industrial demand.
Core Product Advantages
The Composite Zircon Powder features:
- Balanced and stable overall performance
