The ferrosilicon chemistry https://www.sciencedirect.com/topics/chemistry/silicon-monoxide
as per its reference as follows: Production of Ferroalloys <https://www.sciencedirect.com/science/article/pii/B9780080969886000055> Rauf Hurman Eric, in Treatise on Process Metallurgy: Industrial Processes <https://www.sciencedirect.com/book/9780080969886>, 2014 1.10.4.7.2 Fundamental Aspects The overall reaction for the reduction of silica with carbon is simple, but it involves the absorption of considerable quantity of heat as well as attainment of very high temperature in order that the reaction: (1.10.75)SiO2+2C=Si+2CO shall proceed to the right. The standard Gibbs free energy change is zero at 1937 K so that a temperature well in excess of this is needed to drive the reaction in a forward direction. In reality, however, the above reaction does not represent the actual mechanism of the reduction process that occurs through a number of intermediate ones, the principal ones being: (1.10.76)SiO2+3C=SiC+2CO and (1.10.77)SiO2+C=SiOg+CO It is noteworthy to see that reaction (1.10.77) produces silicon monoxide gas at high temperatures which due to its gaseous nature may result in silicon losses if not properly handled and engineered during the process in the submerged arc furnace. Reaction (1.10.76)-producing silicon carbide <https://www.sciencedirect.com/topics/materials-science/carbide> is well-known to occur and accretions of silicon carbide <https://www.sciencedirect.com/topics/materials-science/silicon-carbide> are found in the cooler parts of a furnace when it is shut down and dug out. The reaction is favored by an excess of carbon in the charge. The reason why silicon carbide is not found in the hotter parts of the furnace is probably because it reacts at a high temperature with silicon monoxide as well as with silica itself: (1.10.78)SiC+SiOg=2Si+CO (1.10.79)2SiC+SiO2=3Si+2CO The silicon monoxide reaction (1.10.77) is favored by a deficiency of carbon, and in a furnace operated with a cool top much of this is condensed on the carbon particles <https://www.sciencedirect.com/topics/materials-science/carbon-particle> to be reduced to metal on their descent in the furnace. It can thus be postulated that the overall reaction probably takes place in two stages, namely the formation of silicon carbide in the upper relatively cooler parts of the charge followed by reaction with silicon monoxide as well as with silica in the hotter regions in the vicinity of electrodes, eventually producing liquid silicon. In the making of ferrosilicon <https://www.sciencedirect.com/topics/materials-science/ferrosilicon>, the reduction process is facilitated because the solution of silicon in liquid iron is a process with a favorable free energy change as well as with an exothermic enthalpy change, so the reduction can take place at a lower temperature; for example, the change in free energy where pure liquid silicon dissolves to give a 1% solution: (1.10.80)Sil=Si1%ΔG°=−119,240–25.48TJ/mol at smelting temperatures. Obviously for concentrated solutions, the activity of silicon dissolved in iron needs to be taken in account in calculating the free energy change in any particular set of conditions. In fact, when making low silicon alloys <https://www.sciencedirect.com/topics/materials-science/silicon-alloys> (high Fe content-dilute solutions), the presence of silicon carbide is not detected in contrast to the making of silicon metal. The occurrence of silicon carbide, especially on the hearth, will require the charging of an excess of silica for a time in an attempt to clear and eventually convert it to silicon metal or the charging of iron oxide (generally mill scale) and a reversion of the process to manufacturing ferrosilicon until the SiC accretions have been eliminated. Besides ferrosilicon, three compounds are produced: SiO, CO, and SiC. Sorry, but the only chemically carbon bound compounds invoked with ferrosilicon chemistry is CO and SiC. I know it very hard to disabuse your years long assumption about the nature of the LENR reaction. Such misconceptions are a huge stumbling block to understanding the true nature of the LENR reaction.
