By 1980, special applications accounted for approximately 11% of the total coke production in the United States. These uses include titanium pigments, carbon raisers and synthetic graphite (3 ). A specialty use of green coke is as a high purity reactant in the production of calcium and silicon carbide. (4)... 

Silicon carbide is produced by reduction of Si02 with carbon (coke) in electric resistance furnaces at temperatures of about 2200 °C, According to the purity of the raw materials, the product is green or black in colour and is composed of intergrown SiC crystals. 

Properties For silicon carbide, crystalline form ranges from small to massive crystals in the hexagonal system, the crystals varying from transparent to opaque, with colors from pale green to deep blue or... 

This opened up an inexpensive method of producing dense and complex parts consisting of pure silicon carbide (SSiC). The powders (see Fig. 8) can be molded into a green body by any of the methods used in ceramic molding [93,94], depending on the shape required and the number of pieces involved (see Table 5). Sintering is... 

Therefore, to minimise the volume fraction of silicon carbide required for zero shrinkage, the green density p is to be made as high as possible. Using a mixture of SiC, Al and AI2O3, isostatically... 

Poly(amide)s can be formed by a direct polycondensation with either aromatic or aliphatic dicarboxylic acids. The polymers can be reinforced and thermally stabilized with silicon carbide. These poly(amide)s emit green or blue fluorescence in dilute A-methyl-2-pyrrolidinone solution and in the solid state [77]. 

Silicon carbide shapes with a high green density made by shp casting or by pressmolding SiC powders of bimodal particle size distribution are fired in an electric furnace at temperatures of up to 2500 °C, under the exdusion of air [165, 166). Evaporation and condensation take place at temperatures above 2100 °C, and this...
