Granular silicon carbide (α6H-SiC) was investigated as a photo-reduction alyst for CO2 conversion into methanol using a 355 nm laser from the third harmonic of pulsed Nd:YAG laser and 500 W collimated xenon mercury (XeHg) broad band lamp. The reaction cell was filled with distilled water, α6H-SiC granules and pressurized with CO2 gas at 50 psi. Maximum molar concentration of

For BeO matrix IMF fuels, PuO 2 granules and TRU actinides or YSZ granules containing actinides could be simply dry-mixed with BeO powder and co-sintered to produce a dispersed fuel form. Alternatively, the BeO could be granulated, and the PuO 2 and/or TRU oxides would fill the interstices forming a continuous minor phase that could be recycled in closed fuel cycles.
Silicon-carbide refractories are classified, according to the method of bonding the silicon-carbide granules, as siliceous (formed in the oxidation of carbide), nitride (Si 3 N 4), oxynitride (Si 2 ON 2), and aluminosilie, as well as recrystallized and self-bonded.
Silicon is first converted into chlorosilanes, e.g. RSiCl 3, R 2 SiCl 2 and R 3 SiCl, where R is an organic group. When chloromethane is passed through heated silicon at about 550 K under slight pressure and in the presence of a copper alyst (often copper itself but other copper-containing materials can be used, for example, brass or copper(II) chloride) a volatile mixture of chlorosilanes
β-Silicon carbide-coated uranium monocarbide granules were heated in the range 1500–1850 to investigate the compatibility of β-silicon carbide and uranium monocarbide. Above 1600 a reaction occurred which can be summarized as: 9UC + 4SiC → 5UC 2 + U 3 C 3 Si 2 + USi 2 The reaction appears to involve the formation of a molten shell at the original β-silicon carbide–uranium monocarbide
Silicon Carbide Wafers The use of Silicon Carbide (SiC) in the semiconductor industry has expanded due to its advantageous physical properties, including its hardness, high thermal conductivity and low coefficient of thermal expansion. At PI-KEM we offer a range

Silicon Carbide is a compound of silicon and carbon with chemical formula SiC. Alpha silicon carbide (α-SiC) is the most commonly encountered polymorph. The beta modifiion (β-SiC), with a zinc blende crystal structure (similar to diamond), is formed at temperatures below 1700 °C.
Good granules of silicon carbide obtained with the addition of cement binder with 4% of the mass fraction and at least 24 hours of seasoning. The binder should be added twice by powdering, first in a stirred granulator, and again after manufacture.
