Niobium ethoxide

Description

1. Product Overview

Niobium ethoxide is a high-purity metal alkoxide precursor essential for the synthesis of advanced niobium-based oxides and ferroelectric thin films. Primarily used in the production of specialty ceramics, optical coatings, and next-generation electronic components, it enables precise stoichiometric control in sol-gel and chemical vapor deposition (CVD) processes. Its strategic value lies in enabling high-dielectric-constant materials and energy-efficient capacitors, positioning it as a critical raw material for the $500B+ electronics and advanced materials supply chain.

2. Key Specifications & Technical Characteristics

• Chemical composition: Niobium(V) ethoxide, Nb₂(OC₂H₅)₁₀ (CAS 3236-82-6)

• Purity grade: ≥99.95% (metal basis); option for 99.999% (electronic grade)

• Physical form: Clear, pale yellow to amber liquid

• Density: ~1.26 g/mL at 20°C

• Niobium content: ~25–28% by weight

• Hydrolytic sensitivity: Highly reactive with water; moisture-free handling required

• Packaging options: 1L, 5L, 20L stainless steel drums with PTFE-lined caps; 200L UN-certified drums for bulk

• Shelf life: 12 months in unopened, inert gas-sealed containers stored at 2–8°C

3. Core Industrial Applications

• Advanced ceramics & dielectric layers: Used to synthesize lithium niobate (LiNbO₃) and lead magnesium niobate (PMN) for multilayer ceramic capacitors (MLCCs) and surface acoustic wave (SAW) filters. Advantage: Enables thinner, defect-free films vs. solid-state mixing.

• Optical coatings: High-refractive-index layers in anti-reflective and interference filters. Advantage: Superior uniformity and adhesion compared to sputtering targets.

• Catalysis & nanomaterials: Precursor for niobia-supported catalysts in biomass conversion and olefin epoxidation. Advantage: Higher dispersion of active sites than impregnation methods.

• Ferroelectric memory (FeRAM): SBT (SrBi₂Ta₂O₉) and SBN thin film deposition. Advantage: Low carbon residue upon annealing → fewer electrical leakage paths.

4. Competitive Advantages

• Quality consistency: Batch-to-batch traceable ICP-OES analysis and residual chloride <50 ppm, exceeding industry norms.

• Supply reliability: Dual-sourcing from dedicated Nb ethoxide synthesis lines with 99.8% on-time delivery over 24 months.

• Logistics capability: Temperature-controlled, moisture-protected global shipping via dangerous goods certified partners (UN 3274).

• Price competitiveness: Direct from integrated niobium refining → eliminates broker margin; volume-based tiered pricing.

• Sustainability: Closed-loop ethanol recovery during synthesis reduces VOC emissions by 40% vs. conventional alkoxide processes.

• Technical support: Full material characterization data (NMR, TGA, DTA) available pre-shipment; 48-hour SDS and handling protocol delivery.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 20 kg (net) for standard grade; 5 kg for electronic grade

• BULK 20MT loading capacity: Not applicable for liquid alkoxide – Maximum per ISO tank container: 16 MT (due to density and packaging regulations)

• Standard container loading (20 ft): 80 drums × 200L each → net weight approx. 15.2 MT per container

• Lead time: 14 days ex-works for MOQ; 30 days for full container loads
