Wollastonite vs. Machinable Glass-ceramic
Wollastonite belongs to the oxide-based engineering ceramics classification, while machinable glass-ceramic belongs to the glass and glass-ceramics. There are 7 material properties with values for both materials. Properties with values for just one material (18, in this case) are not shown.
For each property being compared, the top bar is wollastonite and the bottom bar is machinable glass-ceramic.
