Aluminum Titanate (Al2TiO5)

Aluminum titanate is an oxide-based engineering ceramic. It has the lowest fracture toughness and a fairly low thermal conductivity among oxide-based engineering ceramics. The graph bars on the material properties cards below compare aluminum 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.
