Hafnium particles are a high-purity metal material commonly used in various high-tech fields. Hafnium (Hf) is a silver gray transition metal with a high melting point and good corrosion resistance. The purity of hafnium particles is usually very high, reaching over 99.5%, which makes them widely used in fields that require high-purity materials. For example, hafnium particles can be used in semiconductor materials, coating materials, magnetron sputtering targets, etc. These application fields have extremely high requirements for the purity and performance of materials.
