Product Introduction

Product Features & Applications

Refractory zircon powder is produced from selected high-purity zircon sand through flotation, electromagnetic separation, and fine grinding classification processes.

The material features extremely high refractoriness, low thermal expansion coefficient, and excellent dimensional stability under high-temperature conditions. It offers strong resistance to molten metal corrosion and outstanding thermal shock resistance. Impurity content is strictly controlled, ensuring no softening or cracking during high-temperature operation.

Our Refractory Zircon Powder is widely used in high-temperature refractory castables, industrial kiln linings, refractory brick precast parts, metallurgical furnace linings, glass furnace refractory systems, and high-temperature insulating refractory products.

Core Product Advantages

The Refractory Zircon Powder features:

Extremely high refractoriness performance
