Aluminum Oxide vs Silicon Carbide Sandpaper | Uneeda
Due to its razor-sharp grains, silicon carbide will have no problem easily cutting glass, plastic, and metal under light pressure. However, hard woods and metals will present more of a challenge. Regardless of sanding wood or metal, silicon carbide and aluminum oxide can be effectively paired together on the same sanding project, especially in woodworking appliions.
Silicon Nitride | Morgan Technical Ceramics
Silicon nitride is produced in two main ways; Reaction Bonded Silicon Nitride (RBSN), and Hot-Pressed Silicon Nitride (HPSN) and Sintered Silicon Nitride (SSN). RBSN is made by direct reacting compacted silicon powder with nitrogen and produces a relatively low-density product compared with hot pressed and sintered silicon nitride, however the process has only a small volume change allowing
