Hafnium Dioxide Pellets

Product Overview

Hafnium dioxide (HfO₂) pellets are high-purity ceramic materials with a wide bandgap and high dielectric constant, making them ideal for thin-film fabrication and electronic applications. These pellets are white or black, with a density of 9.7 g/cm³ and an exceptionally high melting point of 2500°C. Chemically stable and insoluble in water, they exhibit excellent resistance to harsh conditions. At elevated temperatures, HfO₂ maintains its stability, enabling the deposition of dense and uniform films via electron beam evaporation.

Features

• Wide Bandgap and High Dielectric Constant:Suitable for diverse electronic and optical applications.
• Exceptional High-Temperature Performance:High melting point and thermal stability.
• Strong Chemical Stability:Insoluble in water and resistant to harsh environments.
• Film Deposition Capability:Can be used for sputtering or electron beam evaporation to create durable and stable thin-film structures.

Applications

• Optical Films:Used in the fabrication of UV coatings, anti-reflective coatings, high-reflective coatings, and multi-layer films ranging from UV to near-infrared.
• Electronic Materials:Serves as an insulating oxide thin film for thin-film resistors and dielectric films, widely applied in electronics and semiconductor industries.
• Refractory Materials:Ideal for high-performance refractory products in extreme temperature environments.
• Optoelectronics:Utilized in high-precision optical components and coatings to achieve superior optical performance.
