Polytype Distribution in Circumstellar Silicon Carbide | …

The inferred crystallographic class of circumstellar silicon carbide based on astronomical infrared spectra is controversial. We have directly determined the polytype distribution of circumstellar SiC from transmission electron microscopy of presolar silicon carbide from the Murchison carbonaceous meteorite. Only two polytypes (of a possible several hundred) were observed: cubic 3C and


Silicon carbide is an ideal choice for vehicular appliions and for level IV plates built to withstand aggressive WC-cored projectiles. Diamond Age is capable of manufacturing SiC tiles in small batch quantities and to complex shapes, at very low prices.
