GM-120 Glass Ceramic vs. Hafnia

GM-120 glass ceramic belongs to the glass and glass-ceramics classification, while hafnia belongs to the oxide-based engineering ceramics. There are 7 material properties with values for both materials. Properties with values for just one material (7, in this case) are not shown. Please note that the two materials have significantly dissimilar densities. This means that additional care is required when interpreting the data, because some material properties are based on units of mass, while others are based on units of area or volume.

For each property being compared, the top bar is GM-120 glass ceramic and the bottom bar is hafnia.
