Hafnium chloride powder is a high-purity inorganic salt commonly used in the electronics, chemical, and materials industries, particularly in atomic layer deposition (ALD) and the preparation of high-performance ceramics. Its high volatility and excellent chemical reactivity make it suitable for processes requiring the highest purity and controllable reaction conditions.
We offer Hafnium chloride powder in various particle sizes and packaging specifications, and can customize it to meet your specific needs. Our technical team also provides application consulting and after-sales support to ensure efficient and stable experimental and production processes.
Purity: 99.8% to 99.9%
Volatile and highly reactive, suitable for vapor deposition or high-temperature reaction systems
Particle size control available upon request

Atomic Layer Deposition (ALD): Widely used as a precursor for high-k materials (such as HfO₂) in the preparation of semiconductor transistor gate dielectrics.
High-Performance Ceramics: Used to prepare high-melting-point hafnium-based ceramics with excellent thermal stability and mechanical strength. Catalyst Supports and Additives: Used as a chlorination source or metal additive in certain specialty catalytic reactions to improve catalytic efficiency.
R&D: Used in advanced research projects such as materials chemistry and metal-organic precursor synthesis.
We provide a Certificate of Analysis (COA), Material Safety Data Sheet (MSDS), and other relevant reports with each shipment. We also support third-party testing for enhanced quality assurance.
