Niter and colour case. In the nitre bluing process, polished and cleaned steel parts are immersed in a bath of molten salts—typically potassium nitrate and sodium nitrate (sometimes with 9.4 grams (0.33 oz) of manganese dioxide per pound of total nitrate). The mixture is heated to 310 to 321 °C (590 to 610 °F) and the parts are suspended in ...
[4] [5] [6] The CALPHAD approach is based on the fact that a phase diagram is a manifestation of the equilibrium thermodynamic properties of the system, which are the sum of the properties of the individual phases. [7] It is thus possible to calculate a phase diagram by first assessing the thermodynamic properties of all the phases in a system.
Bluing (steel) is a passivation process in which steel is partially protected against rust Bluing may also refer to: Bluing (fabric), a blue dye used to improve the appearance of fabrics; Bluing (hair), a blue dye used to improve the appearance of hair "bluing" of machine parts to check for tolerances, see engineer's blue
A nitre bed is a similar process used to produce nitrate from excrement. Unlike the leaching-based process of the nitrary, however, one mixes the excrements with soil and waits for soil microbes to convert amino-nitrogen into nitrates by nitrification. The nitrates are extracted from soil with water and then purified into saltpeter by adding ...
