Hafnium Carbide<\/a><\/span><\/strong> sputtering target is a kind of material used in physical vapour deposition (PVD) technology with hafnium carbide as the main component, usually in the form of a plate or disc, with high purity, high density, good thermal and chemical stability, etc. It is a key material for the preparation of high-performance hafnium carbide thin films, which are widely used in the fields of electronics, optics, aerospace and so on.<\/p>\n

VIMATERIAL offers high-purity hafnium carbide sputtering targets, powders, and granules. Custom particle sizes and dimensions are available upon request. Contact us<\/a><\/strong><\/span> for more information.<\/p>\n

Characteristics<\/span><\/h2>\n

Chemical formula: HfC.<\/p>\n

Purity: 99.5% and above. High purity ensures the quality and performance of sputtered films and reduces the impact of impurities on film properties.<\/p>\n

Crystal structure: Has a cubic (rock salt) crystal structure. This crystal structure makes hafnium carbide sputtering targets highly stable and homogeneous, which is conducive to uniform sputtering of atoms and uniform deposition of thin films during the sputtering process.<\/p>\n

Melting point: 3890\u00b0C. The high melting point allows it to maintain a stable structure and properties at high temperatures, making it suitable for applications requiring a high-temperature sputtering process and able to withstand the energy shocks and high temperatures of the sputtering process.<\/p>\n

Theoretical density: approx. 12.2g\/cm\u00b3. The higher density enables the sputtering target to have higher quality and stability, which helps to improve the efficiency of the sputtering process and the quality of the film.<\/p>\n

Sputtering RF type: Suitable for RF sputtering. During the RF sputtering process, the hafnium carbide sputtering target can be effectively bombarded by ions so that the atoms on its surface are sputtered out and deposited on the substrate to form a thin film.<\/p>\n

Applications of Hafnium Carbide Sputtering Target<\/span><\/h2>\n

Semiconductor Field: Used in integrated circuits as thin-film materials for dielectric or insulating layers, helping improve device performance and miniaturization. Also used in semiconductor packaging to enhance conductivity, reliability, and chip protection.<\/p>\n

Aerospace: Used as high-temperature protective coatings on turbine blades, combustion chambers, and thermal protection systems. It improves heat resistance, oxidation resistance, and extends component lifespan.<\/p>\n

Optical Field: Used to prepare optical coatings such as anti-reflective and high-transmittance films. It improves performance in lenses, lasers, solar cells, and display devices.<\/p>\n

Tool Coatings: Applied as a surface coating for cutting tools to increase hardness, wear resistance, and cutting efficiency, especially for machining hard materials.<\/p>\n

Energy Field: Used in fuel cells and energy storage devices as electrode or functional films to improve conductivity and stability.<\/p>\n

Biomedical Field: Used in medical implants and device coatings due to good biocompatibility, corrosion resistance, and wear resistance, improving durability and safety.<\/p>\n

Packaging &Storage<\/span><\/h2>\n

Hafnium carbide sputtering targets are typically vacuum-sealed to prevent oxidation and contamination. They are further protected with moisture-proof and shock-resistant materials like foam, plastic trays, or custom wooden\/metal crates to ensure safe transportation and surface integrity.<\/p>\n

Hafnium carbide targets should be stored in a dry, clean, and temperature-stable environment, away from moisture, corrosive gases, and direct air exposure.<\/p>\n

FAQs<\/span><\/h2>\n

Q1: What is hafnium carbide?<\/strong>
\nA: Hafnium carbide (HfC) is an ultra-high-temperature ceramic compound made of hafnium and carbon. It has an extremely high melting point (over 3800\u00b0C), very high hardness, and excellent thermal and chemical stability, making it suitable for extreme environments.<\/p>\n

Q2: Is hafnium carbide toxic?<\/strong>
\nA: Hafnium carbide is generally considered to have low toxicity in solid form, and it is stable and insoluble under normal conditions. However, like many fine ceramic or refractory particles, inhalation of dust should be avoided during processing, as it may cause respiratory irritation. Proper industrial handling practices are recommended.<\/p>\n

Q3: At what temperature does hafnium carbide (HfC) oxidize?<\/strong>
\nA: Hafnium carbide typically begins to oxidize in air at around 500\u2013700\u00b0C. At higher temperatures, it forms a protective hafnium oxide (HfO\u2082) layer on the surface, which helps slow further oxidation. Its excellent high-temperature resistance makes it suitable for demanding aerospace and industrial applications.<\/p>\n","protected":false},"excerpt":{"rendered":"
