Molybdenum Disilicide Heating Element For Sintering Furnace
Molybdenum disilicide (MoSi2), a refractory metal silicide, is mainly used as a heating element. Of late, it has been recognized as a potential structural ceramic, since it exhibits high elastic modulus and exceptional oxidation resistance at very high temperatures.
MoSi2 and related composites are usually prepared through pressure-assisted sintering methods. Hot isostatic pressing creates intricate shapes, with even density and grain structures. However, this process is more expensive.
MoSi2 has gained a lot of interest because of its attractive properties:
Common properties of hot-pressed MoSi2 are illustrated in Table 1.
Table 1. Typical physical and mechanical properties of molybdenum disilicide
|Melting Point (°C)||2230|
|Young’s Modulus (GPa)||430|
|Bend Strength (MPa)||250|
|Fracture Toughness K1C (MPa.m0.5)||3|
|Resistivity (ohm.cm) (at room temp)||3.5 x10-7|
|Resistivity (ohm.cm) (at 1700 °C)||4.0 x10-6|
Commercially, MoSi2 is widely used in electric heating elements. The material can be potentially applied in high-temperature structural parts.
