Hafnium metal rods are an important metal rod material.
Elemental information: Hafnium is a chemical element with an atomic number of 72 and is located in Group IVB, Period 5 on the periodic table.
Appearance: grey-black in colour.
Density: 13.31 g/cm³.
Mohs hardness: 5.5.
Melting point: 2233°C.
Boiling point: 4602°C.
Thermal conductivity of hafnium: approximately 23.0 W/(m・K).
Crystal structure: Hafnium has a densely packed hexagonal crystal structure.
Nuclear industry: Hafnium metal is used as a control rod in nuclear reactors. Due to its large neutron absorption cross-section, hafnium effectively absorbs neutrons, thereby controlling the rate of nuclear reactions.
Aerospace: Hafnium metal and its alloys are used in the manufacture of high-temperature components for aerospace engines, such as blades and combustion chambers.
Electronics industry: hafnium can be used to manufacture cathode materials for electron tubes, to improve the emission performance and life of electron tubes. In the semiconductor industry, hafnium compounds (e.g. hafnium oxide) are widely used to make gate dielectric materials with high dielectric constants, which are used to improve the performance and integration of integrated circuits.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
