In microelectronics, HfO<sub>2</sub> is a benchmark high-k dielectric used as a gate oxide in advanced integrated circuits, where its high permittivity enables device scaling while maintaining compatibility with silicon processing. It is also applied in infrared and UV optical devices, including protective coatings and night-vision systems, where stable optical performance across a broad wavelength range is required. In energy technologies, HfO<sub>2</sub> coatings are incorporated into solar cell structures to improve optical behavior and durability. Laser-based processing methods use hafnium oxide as a target and thin-film material for producing coatings and nanostructures, taking advantage of its wide bandgap, thermal robustness, and resistance to laser-induced damage.<a href=\"#1\"><span class=\"text-tiny\" style=\"color:#999999;\"><sup>1</sup></span></a></p><p style=\"text-align:justify;\">&nbsp;</p><p style=\"text-align:justify;\"><span style=\"color:#4d4d4d;\">Note: Sputtering targets may contain reduction spots.</span></p>","privateComments":"\n Hafnium oxide has applications in optical coatings, integrated circuits, refractory materials, and hafnium tetrachloride. It can also be used as k- dielectric in DRAM capacitors. Due to its high dielectric constant, it used as potential alternative to silicon material. Furthermore, Hafnium oxide considers as a high dielectric constant of ceramic materials.","specialNotes":"","specialNotesProduct":false,"sds":"public/sds/HfO2.pdf","smiles":"","inchi":"","inchiKey":"","molecularWeight":"","iupac":"","eccn":"","hts":"","atomicNumber":null,"atomicWeight":"210.49 g/mol","meltingPoint":"2758 °C","boilingPoint":"5400 °C","density":"9.68 g/cm³","crystalStructure":"Monoclinic","colorAppearance":"White powder","thermalConductivity":"1.1 W/(m·K)","electricalResistivity":"10^15 Ω·cm","coefficientOfExpansion":"5.8 x 10^-6 /K","electronegativity":null,"neutronCrossSection":"102 barns","electronConfiguration":null,"createdAt":"2023-05-08T15:55:17.000Z","updatedAt":"2026-04-28T21:08:09.056Z","deleted":false,"deletedAt":null,"userChangedById":19,"customContent":"","displayFormula":"","bottomText":"<p style=\"font-family:Calibri;font-size:10.0pt;margin:0in;\" id=\"1\">References:</p><ol class=\"text-tiny\"><li><p style=\"font-family:Calibri;font-size:10.0pt;margin:0in;\">M.
