What is Rock Tuler Grit?
Rock tuler grit is a man-made silicon carbide abrasive. It is inexpensive, extremely hard, and crushes into sharp, angular particles. These properties make it an effective abrasive for cutting, shaping, and smoothing rocks and other hard materials.
Silicon Carbide (SiC) Mirrors - Zygo Corporation
Silicon carbide (SiC) has long been recognized as an attractive mirror material due to its superior mechanical and thermal properties when compared to conventional optical materials. However, the material properties of silicon carbide , which make the material attractive from a design standpoint, have often precluded its use when low cost and rapid delivery of an optical mirror were required.

2017/11/16· It is worth checking this while you have it off if you end up cutting the header flange off as I did. With a little grinding in both of the slots it lined up much more evenly. I used washers too small, then drilled them to a size where the bolts would just fit through without scraping the threads (15/64" worked well for my M6 bolts) for a very snug fit.

But while this suits the tens of kHz switching frequencies demonstrated by silicon devices, hit the much higher MHz speeds of SiC systems and parasitic inductances pose a problem. Parasitic inductance in the power module induces high voltage overshoot and ringing on switching devices, which then increases the device switching loss and EMI emission from the modules.

SiC in e-mobility - Power Electronics News
A major benefit of silicon carbide’s characteristics – in terms of switching speed, heat loss and size – is the 50 percent reduction in energy lost in the form of heat. This saving translates into more efficient power electronics and more energy for the electric motor and therefore for the battery range.
Most of the rocks that make up our planet are forms of silicon dioxide (silies) and we make much use of the sand produced from these rocks - from abrasive sandpaper to making silicon chips. Silicon Carbide ( carborundum ) is an artificial man-made material whose hardness gives it a variety of uses - from abrasive carbide paper to making bullet-proof vests .
