Garnet sand is organic it
SiC Common garnet sand, chemical formula SiC, colorless crystals containing impurities bluish black. Structure similar to diamond, each silicon atom is surrounded by four carbon atoms, each carbon atom surrounded by four silicon atoms, forming "giant molecules." Hardness only to diamond, a density of 3.217 g / cm 3, a melting point of about 2700 ℃ (decomposition sublimation). Chemical stability, high temperature nor with chlorine, oxygen, sulfur, acid reaction, but it can react with the alkali.
Chemically stable silicon carbide are generally not produce carbon dioxide and carbon monoxide.
Garnet sand is an atomic crystal, not organic
Ie organic compounds. Carbon-containing compounds (carbon monoxide, carbon dioxide, carbonates, metal carbides and a few other simple carbon compounds except) or hydrocarbons and their derivatives in general. Organic produce the material basis of life.
NOTE: organic carbon content is simply compounds, inorganic compounds that do not contain carbon. However, the following compounds of carbon, due to the nature close to the other inorganic materials, inorganic they are therefore:
CO, CO2, H2CO3, carbonate (RCO3), (CN) 2, HCN, HCNO, cyanides (RCN), cyanate (RCNO), carbon disulfide, calcium carbide and so on.
Organic substance is determined generally by the combustion method can be judged. However, although most of the inorganic material does not burn, but some inorganic materials can burn (e.g., CO, etc.) and also some organics can not burn.
Organic and inorganic carbon biggest difference is that C is the organic matter in the skeleton as an organic material, is connected to H, O, N, and other elements. The inorganic carbon compounds C is not as compounds of the skeleton.
