Borosilicate Glass vs. Wollastonite
Borosilicate glass belongs to the glass and glass-ceramics classification, while wollastonite belongs to the oxide-based engineering ceramics. There are 7 material properties with values for both materials. Properties with values for just one material (21, in this case) are not shown.
For each property being compared, the top bar is borosilicate glass and the bottom bar is wollastonite.
