Powder Metallurgy

Refractory Products for Powder Metallurgy and Atomisation

Vulcan Refractories supplies high-performance refractory ceramics for metal powder atomisation units used in powder metallurgy, additive manufacturing, and metal injection moulding. These processes involve extreme heat, pressure, and mechanical stress, which demand materials that deliver precision, durability, and consistency.

Our UK-made refractory products help manufacturers maintain consistent powder quality while improving energy efficiency and reducing downtime. As a result, operators benefit from longer service life and stable, repeatable performance in critical production environments.

Applications

Metal powder atomisation systems require precise control and reliable performance. During atomisation, molten metal is transformed into fine powder using high-pressure gas or water streams. Because this process involves rapid temperature change and continuous exposure to wear, refractory components must withstand both thermal shock and chemical attack.

Vulcan’s refractory materials provide exceptional dimensional stability, abrasion resistance, and thermal integrity. Therefore, they ensure consistent powder characteristics and high process reliability in every production cycle. Moreover, our materials are designed to perform across multiple alloys and operational conditions.

Products

We supply a specialist range of refractory ceramics designed for powder metallurgy applications, including:

• Alumina crucibles for holding and pouring molten metal
• Zirconia nozzles for precise metal atomisation and controlled powder flow
• High-temperature cements for installation, sealing, and repair

Each component is produced to tight tolerances and engineered for clean performance under extreme conditions.

Key Features

Vulcan’s refractory products for metal powder atomisation combine strength, purity, and precision:

• Excellent thermal shock resistance for repeated heating and cooling cycles
• High abrasion resistance to maintain dimensional accuracy and extend service life
• Non-reactive with processing metals, ensuring powder purity and preventing contamination
• Process temperatures up to 1650°C
• Exacting tolerances for consistent flow and reliable performance

These qualities make Vulcan’s refractory ceramics a trusted choice for manufacturers requiring stability, repeatability, and precision.
