A technique called transformation toughenening uses a bunch of small particles of zirconia dispersed in alumina causing compressive stresses at crack tips preventing them from propogating and increasing toughness

Grains so tight you can barely see the boundaries 🥵
No cracks have ever propogated in this material 😳
