Barium titanate price

Barium Titanate is a critical ferroelectric ceramic material. For high-end electronic components like MLCCs (Multi-Layer Ceramic Capacitors), you must prioritize purity levels of 99.9% (3N) or higher. Key technical indicators include the Ba/Ti molar ratio, which should be strictly controlled (typically 0.995 to 1.005) to ensure stable dielectric properties. Additionally, verify the particle size distribution (D50); nano-grade powders (under 100nm) are essential for thin-layer capacitors, while micron-grade is suitable for PTC thermistors.

The 'price' of Barium Titanate is heavily influenced by its functional processing. For PTC thermistors, ensure the material is donor-doped (e.g., with rare earth elements). For piezoelectric sensors, check for high piezoelectric constants (d33). If you are sourcing for dielectric formulations, the crystalline phase—specifically the tetragonal phase—is vital for achieving a high dielectric constant. Always request a Scanning Electron Microscope (SEM) report to confirm morphology and grain uniformity.

As a chemical product used in electronics, Barium Titanate must comply with RoHS (Restriction of Hazardous Substances) and REACH regulations to ensure it is free from restricted heavy metals. Suppliers should provide a Material Safety Data Sheet (MSDS) for safe handling and transport. For automotive-grade electronics, look for suppliers following IATF 16949 quality management systems to ensure long-term reliability and traceability.

The price of Barium Titanate is sensitive to the cost of Barium Carbonate and Titanium Dioxide. To mitigate risks, consider long-term framework agreements with price adjustment formulas based on raw material indices. For large-scale procurement, utilize Made-in-China.com's verified supplier system to identify manufacturers with stable production capacities rather than small-scale traders who may struggle with price fluctuations.

Barium Titanate is sensitive to moisture and contamination. Ensure the supplier uses vacuum-sealed double-layer PE bags inside rigid fiber drums or plastic buckets. For sea freight, specify the use of desiccants and ensure the cargo is kept away from acidic materials. Always verify the HS Code (typically 2841.90) to ensure correct customs declaration and avoid unexpected tariffs or clearance delays.

Before finalizing a bulk order, always request a pre-shipment sample from the same production batch. Use Secured Payment services provided by reputable platforms like Made-in-China.com to protect your funds until the third-party inspection (such as SGS or Intertek) confirms that the chemical composition matches the technical data sheet (TDS).
