Silicon Nitride Machining Grinding. Silicon 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 Silicon Nitride body to shrink approximately 20%.

Silicon wafers are used for production of most microchips. Various processes are needed to transfer a silicon crystal ingot into wafers. To ensure high surface quality, the damage layer generated by each of the machining processes (such as lapping and grinding) has to be removed by its subsequent processes.
Abrasives. Silicon Carbide is a ceramic material with an outstanding hardness, only surpassed by diamond, cubic boron nitride and boron carbide. Due to its high abrasion resistance and relatively low cost, Silicon Carbide is used as a loose or fixedabrasive material in a wide variety of applications.

Green Black Silicon carbide grinding wheels commons and differences. Commons: Silicon carbide is an abrasive used for grinding gray iron, chilled iron, brass, soft bronze and aluminum, as well as stone, rubber and other cast iron, nonferrous steel, and nonmetallic material grinding, cutting, or honing.
Silicon wafers are used for production of most microchips. Various processes are needed to transfer a silicon crystal ingot into wafers. To ensure high surface quality, the damage layer generated by each of the machining processes (such as lapping and grinding) has to be removed by its subsequent processes. Therefore it is essential to assess the subsurface damage for each machining process.
