Magnesium Titanate (IEC 60672 Type C-320)
Magnesium titanate is an oxide-based engineering ceramic. It has a moderately high heat capacity among oxide-based engineering ceramics. In addition, it has a moderately high density and a moderately high thermal conductivity.
The graph bars on the material properties cards below compare magnesium titanate to other oxide-based engineering ceramics (top) and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
