Cobalt Boride Nanopowder

Updated: 2026-08-06

Overview

Cobalt boride (CoB) nanopowder with 99.99% purity is an advanced inorganic material prized for its exceptional hardness, thermal stability, and catalytic properties. As a nanoscale powder, it offers high surface area, making it ideal for specialized industrial applications. The material is synthesized through high-temperature reactions or chemical vapor deposition, ensuring ultra-high purity. In B2B markets, this nanopowder is primarily supplied to manufacturers in the chemical, electronics, and materials engineering sectors. Its consistent quality and performance characteristics make it a critical component in high-value industrial processes.

Physical and Chemical Properties

Cobalt boride nanopowder exhibits a hexagonal crystal structure with a density of 7.25 g/cm³, contributing to its remarkable mechanical strength. The material remains stable up to 1,450°C, making it suitable for high-temperature applications. Its nanoscale particle size (typically 50-100 nm) provides enhanced reactivity and sintering performance. Chemically, CoB is inert to water and most organic solvents but may react with strong acids or oxidizers. The 99.99% purity grade ensures minimal metallic impurities, which is crucial for electronic and catalytic applications where trace contaminants could affect performance.

Main Applications

In catalysis, cobalt boride serves as an efficient catalyst for hydrogenation reactions and hydrodesulfurization in petroleum refining. Its high surface area and stability under reducing conditions make it superior to traditional catalysts in certain processes. The material is also used in wear-resistant coatings for industrial tools and components, where its hardness (comparable to tungsten carbide) significantly extends service life. In electronics, it finds application in conductive pastes and as a dopant material for semiconductors. Emerging applications include energy storage systems, where cobalt boride's unique electronic properties show promise for next-generation battery technologies.

Safety and Storage

As a nanomaterial, cobalt boride powder requires careful handling to prevent inhalation exposure. Work should be conducted in fume hoods or with appropriate respiratory protection. The powder may form combustible dust clouds; static electricity control measures are essential. For storage, maintain the product in its original sealed containers under inert gas (argon or nitrogen recommended). Storage areas should be cool, dry, and separate from oxidizers. Shelf life is typically 2-3 years when properly stored, though material should be tested for oxidation before critical applications.

B2B Procurement Guide

Industrial buyers should prioritize suppliers who provide detailed certificates of analysis, including purity verification by ICP-MS and particle size distribution data. Batch-to-batch consistency is critical for catalytic applications. For bulk purchases (10+ kg), negotiate pricing based on volume tiers. Consider suppliers offering customized particle size distributions or surface modifications for specific applications. Lead times for high-purity material typically range from 4-8 weeks; plan procurement accordingly. Quality verification should include independent testing of representative samples, particularly for oxygen content and metallic impurities. For international shipments, ensure proper hazardous materials documentation is provided.
