Niobium ethoxide

Description

1. Product Overview

Niobium ethoxide (Nb(OC₂H₅)₅) is a high-purity metal alkoxide serving as the premier precursor for niobium-based thin films, nanoparticles, and advanced ceramic materials. Its primary industrial use lies in the production of lithium niobate (LiNbO₃) and niobium oxide (Nb₂O₅) layers for electronics, optics, and energy storage systems. The key value proposition is exceptional hydrolytic sensitivity combined with controlled decomposition, enabling atomic-level deposition uniformity that directly enhances device performance. Strategically, it is critical for manufacturers transitioning to next-generation 5G filters, high-refractive-index optical coatings, and solid-state battery components—supply security of this compound directly impacts yield and miniaturization roadmaps.

2. Key Specifications & Technical Characteristics

• Chemical composition: Niobium(V) ethoxide, Nb(OC₂H₅)₅ (CAS 3236-82-6)

• Purity grade: Standard 99.95% trace metals basis; ultra-high purity (99.999%) available for semiconductor applications

• Physical form: Clear pale-yellow to amber liquid

• Density: ~1.35 g/cm³ at 20°C

• Boiling point: 140–142°C at 0.1 mmHg (decomposes before atmospheric boiling)

• Sensitivity: Hydrolyzes rapidly in moist air → requires inert atmosphere handling

• Metal content: ~20–21% Nb by weight

• Packaging options: 1L, 5L, 20L stainless steel bubblers; 200L drum with PTFE-lined cap; custom cylinders for CVD/ALD direct-to-tool feed

• Shelf life: 12 months from date of analysis when stored under dry nitrogen at 0–25°C

3. Core Industrial Applications

• Advanced electronics (5G/6G RF filters): Used to deposit lithium niobate thin films for surface acoustic wave (SAW) and bulk acoustic wave (BAW) filters. Outperforms solid-state synthesis via lower annealing temperatures (450°C vs. >700°C), preserving underlying CMOS circuitry.

• Optical coatings & waveguides: Enables high-refractive-index layers (n ~ 2.2–2.4) with <0.5% scattering loss. Beats sputtering targets in step coverage on 3D-structured glass and polymer substrates.

• Solid-state battery electrolytes: Produces Nb-doped LLZO (Li₇La₃Zr₂O₁₂) with 2x higher ionic conductivity than undoped versions. Cost advantage over hafnium alkoxides at comparable electrochemical stability.

• Catalyst supports: Forms mesoporous Nb₂O₅ with acid site density >0.3 mmol/g – superior thermal stability (up to 800°C) vs. silica or titania in biomass conversion.

4. Competitive Advantages

• Quality consistency: Lot-to-lot variation < ±2% in Nb assay (verified by ICP-OES and NMR), ensuring repeatable film thickness across multi-ton annual purchases.

• Supply reliability: Dedicated manufacturing line with 72-hour emergency dispatch from regional hubs (US, EU, Asia); on-site nitrogen-blanketed storage guarantees zero hydrolysis defects.

• Logistics capability: UN-compliant packaging with real-time hazmat tracking; temperature-controlled cross-dock reduces transit degradation to <0.1% per 1,000 km.

• Price competitiveness: Direct-from-kiln pricing – 15–20% below specialty chemical distributors at 20 MT contract volumes, with volume-based rebates.

• Sustainability: Closed-loop ethanol recovery in production (reduces virgin solvent use by 60%); full REACH and TSCA compliance documentation included.

• Technical support: Free process optimization guide (CVD/ALD parameter mapping) + batch certificate with moisture and residual chloride analysis.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 5 kg (lab/R&D qualification); 500 kg (industrial pilot); 20 MT (full production contract)

• BULK 20 MT loading capacity per container:

  • Standard ISO tank container (20 ft): 20 MT net (one full shipment)

  • Alternatively: 80 × 200L drums (net ~16 MT per 20 ft container – lower density due to packaging volume)

• Lead time (20 MT): 28 days from order confirmation + 14 days ocean freight (FOB manufacturing port)
