To grow an ingot, the first step is to heat the silicon to 1420°C, above the melting point of silicon. Once the polycrystalline and dopant combination has been liquified, a single silicon crystal, the seed, is positioned on top of the melt, barely touching the surface. The seed has the same crystal orientation required in the finished ingot.
In the CZ method, polycrystaline silicon nuggets are placed in a quartz crucible, which is set in a graphite crucible surrounded by graphite heaters in the crystal pulling chamber. These nuggets are melted by heating in an Argon atmosphere under vacuum and then pulled slowly using a seed crystal. ... Peripheral Grinding

Silicon carbide: Silicon carbide is an extremely hard grain that is very sharp and fast cutting but friable, not as tough as other grains. Silicon carbide/aluminum oxide blend: A wheel made from a blend of silicon carbide and aluminum oxide provides ideal grinding for aluminum and other soft alloys. These grains offer extended life spans and ...
Grinding Wheels for Angle Grinders— Use on Nonmetals. Silicon carbide cuts through concrete and stone without generating much heat. Wheels are also known as Type 27 wheels, raised-hub wheels, and grinding discs.
Grinding and Polishing Guide. Grinding should commence with the finest grit size that will establish an initially flat surface and remove the effects of sectioning within a few minutes. An abrasive grit size of 180-240 [P180-P280] is coarse enough to use on specimen surfaces sectioned by an abrasive wheel. Hack-sawed, bandsawed, or other rough ...
