Zirconium Oxide By-product

Description

1. Product Overview
This high-purity Zirconium Oxide By-product is an industrial intermediate recovered from primary zirconium refining streams, offering a cost-effective alternative to virgin zirconia for non-critical high-performance applications. Its primary industrial use lies in abrasive blasting media, refractory additives, and ceramic pigment formulations where controlled hafnium content is not a constraint. The key value proposition is delivering consistent ZrO₂+HfO₂ content at 40–60% of virgin material cost, enabling manufacturers to reduce raw material expenses without sacrificing thermal stability or wear resistance. Strategically important in markets facing zircon sand supply volatility, this by-product secures secondary supply chains for foundries, abrasives producers, and specialty ceramics manufacturers.

2. Key Specifications & Technical Characteristics

• Chemical composition: ZrO₂ + HfO₂ (typically 92–96%); residual SiO₂, TiO₂, Fe₂O₃ (<3% combined)

• Purity level: Industrial grade (not pharmaceutical/nuclear grade); hafnium not removed

• Physical characteristics: Off-white to light tan powder; angular to sub-angular particle morphology

• Particle size distribution: D50 5–45 µm (standard); custom milling available

• Bulk density: Tapped 1.8–2.2 g/cm³; loose 1.2–1.5 g/cm³

• Packaging options: 1 MT bulk bags (FIBC), 25 kg laminated paper bags, or pneumatic tanker for bulk powder

• Shelf life: 24 months when stored in dry, covered conditions (≤2% moisture absorption over 12 months)

3. Core Industrial Applications

• Primary industries: Abrasives manufacturing, refractory production, foundry consumables, ceramic pigments, and structural ceramics

• Specific use cases:

  • Abrasive blasting media (blends with alumina or silica for surface preparation on steel and titanium)

  • Refractory castables and bricks (as a stabilizer and anti-wetting agent at >1500°C)

  • Ceramic pigments (zirconium praseodymium yellow and vanadium blue formulations)

  • Foundry facing agents (prevents metal penetration in sand molds)

• Performance advantage: Compared to virgin zirconia, this by-product delivers 90–95% of the thermal shock resistance and hardness at half the landed cost. It outperforms alumina in high-temperature wear applications due to lower thermal conductivity and superior chemical inertness against molten metals.

• Efficiency gain: Reduces raw material spend by $400–$800 per metric ton vs. primary zirconium oxide, enabling price-competitive downstream products.

4. Competitive Advantages

• Quality consistency: Lot-to-lot variability controlled via ISO 9001:2025 certified blending and sampling; each shipment includes COA with XRD phase analysis

• Supply reliability: Sourced from continuous zirconium chemical production (annual volume >8,000 MT), ensuring 52-week forward allocation available

• Logistics capability: Dual sourcing from two geographically separate processing sites (Asia and Americas) to mitigate regional disruption risk

• Price competitiveness: Fixed quarterly pricing with volume-based rebates; spot pricing at 55% of LME zirconia equivalent

• Sustainability benefits: Reduces landfill waste from primary refining by >90% per ton purchased; eligible for Scope 3 emissions reduction reporting

• Technical support: Free process optimization consultation (milling, blending, or compaction recommendations) and on-site trials for contract volumes ≥100 MT

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 20 MT (bulk) or 5 MT (bagged samples)

• BULK 20MT loading capacity: 20 MT net per 20-foot dry container (floor-loaded, no pallets) — maximizes container utilization; 22 MT possible with palletized bags depending on destination weight limits

• Loading capacity per container (standard 20’ DV): 20 MT (bulk bags, single-stack) / 18 MT (palletized 25 kg bags, double-stacked)

• Incoterms supported: FOB (loading port), CIF, CFR, EXW

• Lead time: 15 days from order confirmation for stock grades; 30 days for custom particle size
