Packaging & Storage

Hafnium boride sputtering targets are typically vacuum-sealed to prevent oxidation. They are protected with moisture-proof and shock-resistant materials, such as foam or custom crates, to avoid damage and contamination during transport.

Hafnium boride targets should be stored in a dry, clean, and low-humidity environment. They should be kept sealed and protected from air, moisture, and corrosive substances, preferably in a desiccator atmosphere to maintain stability and purity.
