Aluminum Oxide: Cuts well, wears well Aluminum oxide is the most common abrasive used for tool sharpening because, while it’s not as hard as aluminum carbide, it still cuts steel well. It’s not as brittle, so the particles last longer, but since those particles don’t fracture as easily, the wear smooth causing the paper to cut slower over time.
Aluminum Nitride - Precision Ceramics
Aluminum Nitride can be machined in green, biscuit, or fully dense states. While in the green or biscuit form it can be machined relatively easily into complex geometries. However, the sintering process that is required to fully densify the material causes the Aluminum Nitride body to shrink approximately 20%.

Successful Appliion Of Ceramic Inserts | Modern …
The silicon carbide reinforcements of these ceramic inserts are often referred to as whiskers because they resele small hairs when examined under a microscope. To find out more about ceramic inserts and especially how their appliion in metalworking differs from carbide inserts, we talked to Keith Smith, manager marketing and international sales for Greenleaf Corporation (Saegertown
Reliability of SiC-MOSFETs | Basic Knowledge | ROHM …
Body diode conduction degradation SiC-MOSFETs are thought to have a fault mode called body diode conduction degradation. This is a mode in which, when a forward current continues to flow in the body diode of a MOSFET, faults known as stacking faults are expanded due to the recoination energy of electron-hole pairs, affecting the current path and resulting in increases in the on-resistance
