Hi, I am searching for the sound speed of liquid zinc. (Temperature approx. 450°C) The density of the zinc at this temperature is available (approx. 6557kg/m^3). So only the compression module would be needed for the calculation of the soundspeed. Further, how could I do the speed measurements myself? I have a small steeltank, where I could melt the zinc. My problem is the coupling to the tank without destroying the transducer. Every idea is appreciated. Thank yor for your answers. Johann Hoffelner

Re: Sound speed of liquid zinc Mr. Hoffelner, We have developed an ultrasonic transducer that operates without damage at temperatures as high as 900C. We have briefly tested the transducer in molten aluminum (up to 750C). Some information on the transducer can be found in the article at: http:// www2.tms.org/pubs/journals/JOM/9609/Stubbs-9609.html
