Synthetic moissanite is also known as silicon carbide after its chemistry (in industry moissanite is known as the man-made abrasive Carborundum). Moissanite is used as a diamond substitute as it is transparent and hard with a slightly higher refractive index than diamond.
The increasing use of color enhancement and “anti-scratch” (silicon carbide) coatings, which are virtually invisible and sometimes too thin to be detected with instruments. With advances in nanotechnology, more research is needed to develop detection strategies.

Drainage pumps for extracting ground water Dewatering refers to the solid-liquid separation process of extracting and draining ground water or surface water, usually from a construction site but also river beds and mine shafts. A dewatering pump, or a drainage pump
Silicon carbide ceramics with little or no grain boundary impurities maintain their strength to very high temperatures, approaching 1600 C with no strength loss. Chemical purity, resistance to chemical attack at temperature, and strength retention at high temperatures has made this material very popular as wafer tray supports and paddles in semiconductor furnaces.

He found it as tiny bits of silicon carbide, inside a meteorite in canyon Diablo, Arizona. The stone was named after him. In the year 1959, moissanite was found with an inclusion of kierlite in a diamond mine in Yakutia, Siberia and Wyoming- Western United States.
Silicon carbide. In a similar way, silicone carbide is great for making your stones super smooth and free from coarse scratches. Safety glasses. If you’re sawing any of your rock slabs or cutting gemstones, always remeer to wear safety glasses. A trim saw or
One example is silicon carbide (SiC), which – in contrast to diamond – is not easy to produce. High purity SiC can also be used as gemstone due to its hardness and refractive index being close to that of diamond. However SiC is in demand not because it looks
It was Dr. Henri Moissan who discovered the silicon carbide mineral, lodged inside a meteorite in Canyon Diablo in Arizona, USA in 1983 and it is him the mineral is named after. Moissanite stones are often mistaken for either synthetic diamonds or even real diamonds such is their likeness.
