CAS 12055-23-1: Hafnium oxide

Description:Hafnium oxide, also known as hafnia, is a chemical compound with the formula HfO₂. It is a white, crystalline solid that exhibits high thermal stability and is insoluble in water. Hafnium oxide has a high melting point and is known for its excellent dielectric properties, making it valuable in the electronics industry, particularly in the production of capacitors and as a gate dielectric in transistors. The compound is also characterized by its high refractive index and is used in optical coatings. Hafnium oxide can exist in different crystalline forms, including monoclinic, tetragonal, and cubic phases, with the tetragonal phase being stable at high temperatures. Additionally, hafnia is chemically resistant and can withstand harsh environments, which makes it suitable for applications in nuclear reactors and as a protective coating. Its unique properties also make it a candidate for use in advanced materials and nanotechnology. Overall, hafnium oxide is a versatile material with significant industrial and technological applications.
