EC number: 282-217-2 | CAS number: 84144-95-6 Product of silicothermic reduction of molybdic oxide. Composed primarily of fused silica, alumina, and calcium and iron oxides and silicates, with a small amount of residual molybdenum.

- no
- Type of method:
- other: no data
- Melting / freezing pt.:
- >= 1 100 - <= 1 600 °C
- Decomposition:
- no
- Sublimation:
- no
- Conclusions:
- Ferromolybdenum slags primarily consist of oxides of silicon, aluminium, calcium and iron, in a glass-like, mostly amorphous matrix. According to phase-diagrams for the three-phase-system Al2O3-CaO-SiO2, the melting point of such materials is approximately in the range of 1100 -1600 °C, depending on actual composition. This is in agreement with temperature measurements conducted during the production process.
