Zirconium dioxide

Description:
Zirconium dioxide, also known as zirconia, is a white crystalline oxide of zirconium with the chemical formula ZrO2. It is characterized by its high melting point, excellent thermal stability, and low thermal conductivity, making it suitable for high-temperature applications. Zirconium dioxide exhibits remarkable mechanical properties, including high strength and toughness, which contribute to its use in ceramics and dental applications. It is also chemically inert, resistant to corrosion, and does not react with most acids and bases, enhancing its utility in various industrial processes. Zirconia can exist in different crystalline forms, including monoclinic, tetragonal, and cubic phases, with the tetragonal and cubic forms being stabilized by the addition of dopants like yttria. This stabilization allows for its use in applications such as oxygen sensors, fuel cells, and as a refractory material. Additionally, zirconium dioxide is biocompatible, making it a popular choice in medical implants and dental prosthetics. Overall, its unique combination of properties makes zirconium dioxide a versatile material in multiple fields.
