Titanium diboride

When purchasing Titanium Diboride, the most critical factors are purity (typically 98.5% to 99.9%), particle size distribution (D50), and oxygen content. For high-performance ceramics or conductive applications, a lower oxygen content (<0.5%) is essential to ensure optimal thermal and electrical conductivity. You should also verify the crystalline structure via XRD reports to ensure high phase purity.

TiB2 is primarily used in aluminum electrolysis cathodes due to its excellent wettability with molten aluminum and chemical resistance. It is also widely applied in the production of ceramic cutting tools, wear-resistant coatings, and evaporation boats for vacuum metallization. Its high Vickers hardness (approx. 25-35 GPa) makes it ideal for armor plating and aerospace components.

As a chemical product, it must be accompanied by a comprehensive Material Safety Data Sheet (MSDS). For international trade, ensure the supplier complies with REACH (EU) or TSCA (US) regulations. Since it is often transported as a fine powder, it must meet IMDG/IATA packaging standards for non-flammable solids to prevent dust explosions or inhalation risks during transit.

Prioritize suppliers with ISO 9001:2015 certification and those listed as Audited Suppliers. Request a Certificate of Analysis (COA) for each batch and ask for SEM (Scanning Electron Microscopy) images to verify particle morphology. For large-scale industrial projects, it is highly recommended to perform a third-party lab test (e.g., SGS or Intertek) before final shipment.

The primary risks include moisture absorption during sea transit and batch inconsistency. Titanium Diboride is sensitive to oxidation if not sealed correctly. Ensure the supplier uses vacuum-sealed aluminum foil bags inside reinforced fiber drums. Always use Trade Assurance or secure payment terms to mitigate the risk of receiving sub-standard purity levels.

Pricing for TiB2 is heavily influenced by the cost of raw titanium and boron. For bulk orders (over 500kg), you can typically negotiate a 10-15% discount. If you are a first-time buyer, request a paid sample (1-5kg) to test in your production line before committing to a high MOQ. Discuss long-term supply contracts to hedge against raw material price volatility.

Ensure the correct HS Code (typically 2850.00) is used for customs declaration to avoid delays. Because it is a specialized technical ceramic material, some countries may require an End-User Statement to ensure it is not used for restricted military applications. For shipping, FOB (Free On Board) is recommended if you have a reliable forwarder, but CIF (Cost, Insurance, and Freight) is often more convenient for smaller trial batches.
