Synthesis of silicon carbide (SiC) by carbothermal reduction of quartz in a CH 4–H 2–Ar gas mixture was investigated in a laboratory fixed-bed reactor in the temperature range of 1573 K to 1823 K (1300 C to 1550 C). The reduction process was monitored by an
Based on this 1:3 molar ratio, we can do some math tricks to get to the mass of carbon we need. We''ll go backwards, converting the mass of SiO2 used to moles using its molra mass (60.08 g/mol), use our 1:3 ratio to figure out how many moles of Carbon is used in this reaction, and then convert to grams of carbon to get our mass of carbon used in this reaction.
