Phase Diagram of Silica Polymorphs Figure 1 shows the temperature and pressure conditions at which SiO 2 polymorphs are stable in a so-called phase diagram of SiO 2 . A complete phase diagram would also show the conditions where SiO 2 forms a gas, above 2477°C at normal pressures, but since I don''t have data on pressure dependence for that area, this temperature range is omitted.

Phase Transformations and Complex Properties - Cast Irons

Cast Irons Miguel Angel Yescas-Gonzalez and H. K. D. H. Bhadeshia Cast irons typically contain 2-4 wt% of carbon with a high silicon concentrations and a greater concentration of impurities than steels. The carbon equivalent (CE) of a cast iron helps to distinguish the grey irons which cool into a microstructure containing graphite and and the white irons where the carbon is present mainly as
