Ferrosilicon Nitride Lump

 

Thermal properties:
Sintered silicon nitride has a low thermal expansion coefficient of 2.53×10-6/℃ and a thermal conductivity of 18.42 W/m·K, so it has excellent thermal shock resistance and good thermal stability, and can be used for a long time at high temperatures. It can be used up to 1400℃ in an oxidizing atmosphere and up to 1850℃ in a neutral or reducing atmosphere.

Mechanical properties:
Silicon nitride has high mechanical strength. The flexural strength of general hot-pressed products is 500-700MPa, and the highest can reach 1000-1200MPa; the flexural strength after reaction sintering is 200MPa, and the highest can reach 300-400MPa. Although the room temperature strength of reaction sintered products is not high, its strength does not decrease at high temperatures of 1200-1350℃. Silicon nitride has low high temperature creep. For example, reaction-sintered silicon nitride has a load of 24 MPa at 1200°C and a deformation of 0.5% after 1000 hours.
