1. Performance and use

Hafnium oxide (HfO2) is a white crystalline powder. Pure hafnium oxide exists in three forms, one is amorphous and the other two are crystalline. When unstable compounds such as hafnium hydroxide and hafnium oxychloride are calcined at<400 ℃, amorphous hafnium oxide can be obtained. Continue heating hafnium oxide to 450-480 ℃ to begin transforming into monoclinic crystals. Continue heating to 1000-1650 ℃ to gradually increase the lattice constant and transform into a monomer of four hafnium oxide molecules. When the temperature is between 1700 and 1865 ℃, it begins to transform into a tetragonal crystal system.
