zirconium sand 80/120mesh

zirconium sand 80/120mesh

Zirconium Sand (80/120 Mesh) is a high-quality, medium-coarse zircon silicate (ZrSiO₄) mineral, precisely screened to a particle size range of 80 to 120 mesh (approximately 125 to 180 microns). This carefully controlled gradation offers an excellent balance of permeability, strength, and thermal resistance, making it the preferred choice for demanding foundry operations, refractory applications, and heavy-section investment casting.

Key Features & Benefits

• Optimized Particle Distribution: The 80/120 mesh specification provides enhanced permeability and gas venting during metal pouring while maintaining adequate surface finish. This coarse-yet-controlled gradation reduces binder requirements and improves core and mold strength.

• Superior Thermal Performance: With a melting point exceeding 2200°C, low thermal expansion, and excellent resistance to thermal shock, zirconium sand outperforms conventional silica sands in high-temperature environments, minimizing defects such as veining, metal penetration, and burn-on.

• Chemically Inert & Non-Wetting: Zircon sand exhibits low reactivity with molten metals, including steel, iron, and superalloys. Its non-wetting properties prevent molten metal adhesion, ensuring clean casting surfaces and easier shakeout.

• High Refractoriness & Density: The high specific gravity (approximately 4.6–4.7 g/cm³) and dense particle structure provide excellent chilling effect, promoting directional solidification and reducing hot tear risks in thick-section castings.

Typical Applications

• Foundry Cores & Molds: Ideal for medium-to-large ferrous and non-ferrous castings requiring excellent permeability and thermal stability. Commonly used in engine blocks, valve bodies, pump housings, and heavy machinery components.

• Investment Casting Back-Up Sand: Serves as a coarse back-up stucco layer for ceramic shell systems, providing structural strength and gas permeability for large or heavy-wall precision castings.

• Refractory Shapes & Monolithics: Used as a key aggregate in zircon-based refractory bricks, crucibles, ladle linings, and tundish nozzles for steelmaking and glass manufacturing.

• Abrasives & Grinding Media: Provides exceptional wear resistance and cutting efficiency in abrasive wheels, sandpaper, and surface preparation applications.
