spiegeleisen การใช้

Spiegeleisen ( an iron-carbon-manganese alloy ) was added to the mixture.
Mushet carried out experiments on the sample, based on those he had previously carried out with spiegeleisen.
This removed the phosphorus impurities as slag, produced by chemical reaction with the liner, and no longer required spiegeleisen.
In more technical uses, there are also spiegeleisen, an alloy of iron, manganese, and carbon; and stellite, an alloy of cobalt, chromium, tungsten, and carbon.
His method was to first burn off, as far as possible, " all " the impurities and carbon, then reintroduce carbon and manganese by adding an exact amount of spiegeleisen.
