Alloy is confusing. Why would Ferrosilicon have one molecular weight (28.0855gmol−1) value but various density values (7.87∼3.44gmol−1) each for a different silicon (Si) content?
Why would the alloy have a molecular formula?
If iron also forms an alloy with carbon, maybe annealing carbon alone (ie Z=6,ma=12.0107gmol−1) in the mixture of density that varies with the percentage content of carbon, will form a new "diamond-iron" solid.
In the case above, we would use instead SiO2 and iron to obtain a "quartz-iron" solid.
What are the values of Tbooms and Tps?
Why stop there; subject the solids to annealing temperatures with the appropriate additives and make steels; "diamond-steel" and "quartz steel".
