Sonic velocity of Si3N4

Sonic velocity of Si3N4

(OP)
Hi,

I am looking for sonic velocity of silicon nitride but I could not find it anyway.Can somebody help me?

Thanks,

RE: Sonic velocity of Si3N4

Here is the data that I have. I have no information as to the specific material.  

Silicon Nitride.

VL  mm/micro s  11.06

VS  mm/micro s  6.25

Density    g/cm3   3.27

ZL Mrayl 36.0

RE: Sonic velocity of Si3N4

The Coors data doesn't list sonic velocities, but

Hot pressed, density = 3.31 and modulus = 311GPa
reaction bonded, density = 2.5 and modulus = 179GPa

And I don't remember how to calculate it.

= = = = = = = = = = = = = = = = = = = =
Corrosion never sleeps, but it can be managed.
