Abstract The Nicalon silicon carbide fibre has been studied by X-ray photoelectron spectroscopy. Elements entering the fibre are carbon, silicon and oxygen. In addition to previously reported chemical entities (silicon carbide, silica and graphitic carbon) evidence is
mp-8062: SiC (cubic, F-43m, 216)
SiC is Zincblende, Sphalerite structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Si4+ is bonded to four equivalent C4- atoms to form corner-sharing SiC4 tetrahedra. All Si–C bond lengths are 1.90 Å. C4- is bonded to four
Silicon Carbide (artificial): Mineral information, data and …
Artificial silicon carbide (SiC) is included in this database as samples of it are frequently sold in "rock shops" and on internet auctions, sometimes under the name ''carborundum'', sometimes as ''moissanite'' (there is a very rare natural silicon carbide mineral with the name moissanite), but most frequently with no name at all.
Measuring Silicon Carbide Particle Size - HORIBA
Measuring Silicon Carbide Particle Size Due to its high hardness, silicon carbide is used in many abrasive appliions either as a slurry or fixed in a matrix such as grinding wheels. It is also highly abrasion-resistant, so can be used in parts such as nozzles, seals, and bearing components.

Kanthal® Globar heating elements — Kanthal®
SiC heating elements designed for the most challenging appliions where conventional silicon carbide elements are unsuitable. Kanthal Globar HD SiC heating elements feature hot zones of high density, low permeability, reaction-bonded silicon carbide, which is highly resistant to oxidation, and to chemical attack by process volatiles and reactive atmospheres.
Boron Carbide - an overview | ScienceDirect Topics
Boron carbide is not attacked by cold chemical reagents; it is oxidized by hot oxidizing acids (HNO 3, H 2 SO 4, HClO 4 …) and fused salts. Boron carbide reacts little with liquid sodium (loosening of a few grains 95 ), when used in metal-cooled reactors with opened absorber elements; it reacts with most metals to form borides or carbo-borides. 96
Mainstream silicon carbide grains from meteorites - …
Primitive meteorites contain small quantities (up to several ppm) of presolar silicon carbide (SiC) grains. These grains show highly anomalous isotopic compositions of the major elements C and Si and of the trace elements N, Mg, Ca, Ti, Sr, Zr, Mo, Ba, Nd, Sm, Dy, and the noble gases. The isotopic compositions of most grains (``Mainstream'''' and the isotopically related minor type A, B, Y, and
