2020/6/30· Therefore, the mass fraction of SiC can be estimated and the molar ratio can be determined subsequently based on the molar mass, and obtained result is displayed in Fig. 5. Molar ratio of SiC increases from 2.7% to 17% when the initial C/Si ranges from 0.5 to 3, and this conclusion is consistent with the observation from TEM figures.
Silicon dioxide reacts with carbon upon heating to …
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.

A comprehensive systematic method for chemical vapor deposition modeling consisting of seven well-defined steps is presented. The method is general in the sense that it is not adapted to a certain type of chemistry or reactor configuration. The method is demonstrated using silicon carbide (SiC) as a model system, with accurate matching to measured data without tuning of the model. We
