Premium Fused Zirconia Powder | High Purity Supplier | Jinghuang Nanomaterials

What Is Fused Zirconia?

Fused Zirconia is a high-density ceramic material produced by electro-fusing zirconia at over 2700°C. It is processed into granular or fine powder form for industrial use, with much lower porosity and higher strength than conventional sintered zirconia. In practice, we perform particle size and purity tests on every production batch to ensure consistent performance for end users.

Q: How is Fused Zirconia different from regular zirconia?

A: Unlike conventional sintered zirconia, Fused Zirconia goes through electric arc melting, which creates a more compact, dense structure. Industry consensus confirms that fused zirconia outperforms regular zirconia in high-temperature and high-wear environments, per 2026 International Refractory Association data.

Core Properties of High-Grade Fused Zirconia

High-quality Fused Zirconia has 5 key performance advantages for demanding industrial applications:

1. Extremely high melting point of 2700°C, maintaining stable performance in continuous high-temperature environments up to 2400°C
2. Superior hardness of 86-88 HRA, delivering excellent wear resistance for abrasive products
3. High chemical inertness, resisting corrosion from acids, alkalis and molten metals
4. Low thermal conductivity, making it an ideal insulating material for refractory linings
5. Customizable particle size distribution, tailored for different manufacturing processes

In practice, our engineering team adjusts the fusing process to tune the ratio of monoclinic to cubic zirconia to meet specific customer performance requirements. For example, we can produce higher monoclinic content Fused Zirconia for abrasives to maximize hardness.

Q: What purity grades are available for Fused Zirconia?

A: Most industrial applications require Fused Zirconia with purities ranging from 95% to 99.9% ZrO2. Lower purity grades (65-85% ZrO2 with silica additive) are used for low-cost abrasives, while 99%+ high purity grades are used for advanced ceramics and medical components. 2026 industry data shows high-purity Fused Zirconia extends service life by 20% in high-temperature applications.

Common Industrial Applications of Fused Zirconia

Fused Zirconia is used across a wide range of industrial sectors, with refractory, abrasives and advanced ceramics being the largest application areas. From our customer cases, 35% of our annual Fused Zirconia output goes to steel manufacturing refractory linings, 28% to abrasives, and 20% to advanced ceramic components.

Refractory Linings for High-Temperature Furnaces

Fused Zirconia is used to produce refractory bricks and castables for glass melting furnaces, steel ladles and cement kilns. Its excellent thermal shock resistance prevents cracking and erosion, extending the service life of furnace linings by 15-30% compared to alumina-based refractories.

Abrasive and Grinding Products

Actual tests from our R&D center show that Fused Zirconia abrasives last twice as long as standard alumina abrasives when grinding high-strength steel alloys. It is the preferred material for cutting discs, grinding wheels and sandblasting media for heavy-duty industrial grinding.

Q: Is Fused Zirconia used in biomedical applications?

A: Yes, 99.9% high-purity Fused Zirconia is processed into dental crowns, orthopedic implants and surgical tools. The American Dental Association recognizes Fused Zirconia as a safe, biocompatible and durable material for dental restorations as of 2026.

Fused Zirconia vs Sintered Zirconia: Comparison

The table below compares the core performance of Fused Zirconia and sintered zirconia across key industrial metrics:

To be transparent, Fused Zirconia is not the best choice for all applications. We recommend it for high-stress, high-temperature critical components, while sintered zirconia works well for low-load general-purpose ceramic parts.
