{Could anyone supply me with physical constants of silicon nitride? The usual
{standard references (Wolfe, INSPEC, CRC) don't seem to have much related to
{this material. Thanks in advance. Mike King
Silicon nitride Density Elasitc Modulus Poisson's ratio
3.44 304 GPa 0.24
Koop Hardness Modulus of Rupture
2200 414-580 MPa
Electrical Resistivity Thermal Conductivity
>10^12 Ohm-meter 16-33 W/m-K
Coefficient of Thermal Expansion Melting Temperature
3.6 (C)^-1 x10^6 ~1900 C
