For professionals in advanced materials science, electronics, and chemical synthesis, Hafnium Tetrachloride (HfCl4), identified by CAS number 13499-05-03, is a chemical intermediate of significant importance. Whether you are looking to buy Hafnium Tetrachloride for research or large-scale industrial applications, understanding key considerations is vital. This guide aims to equip you with the knowledge to make informed purchasing decisions.

Understanding Purity Requirements: At a minimum, Hafnium Tetrachloride is often available at 98% purity. However, for highly sensitive applications, particularly in microelectronics where it serves as a precursor for high-k dielectrics, even higher purities might be specified. Impurities can critically affect device performance. When sourcing, always confirm the exact purity level and inquire about the analytical methods used for verification. Working with a reputable manufacturer in China that provides detailed Certificates of Analysis (CoA) is essential.

Key Applications to Consider: Hafnium Tetrachloride's utility spans several advanced sectors:

  • Microelectronics: Precursor for hafnium oxide (HfO2) in high-k gate dielectrics.
  • Catalysis: Acts as a Lewis acid catalyst in organic synthesis and polymerization.
  • Thin Film Deposition: Used in CVD and ALD processes for coatings and advanced materials.
  • Nuclear Applications: As a precursor for hafnium-based neutron absorbers.
Your intended application will dictate the required purity and quantity.

Handling and Safety: Hafnium Tetrachloride is a corrosive solid and is highly sensitive to moisture, hydrolyzing readily to form hydrogen chloride gas. Proper handling requires a dry environment, protective equipment (gloves, eye protection, respiratory protection), and well-ventilated areas. Always consult the Safety Data Sheet (SDS) provided by the supplier.

Choosing a Reliable Supplier: When you need to purchase Hafnium Tetrachloride, especially from China, due diligence on the supplier is crucial. Look for manufacturers with a proven track record, strong quality control measures, and transparent communication. Factors like production capacity, adherence to international standards (e.g., ISO certification), and competitive Hafnium Tetrachloride price are important considerations.
