Simultaneous measurements of heat capacity, electrical resistivity and hemispherical total emittance of zirconium in the temperature range 1500 to 2100 K by a subsecond duration, pulse heating technique are described. The results are expressed by the relations:C  p   =  36.65  -  1.435  ×    10    -  2    T  +  6.624  ×    10    -  6T  2ρ  =  87.95  +  1.946  ×    10    -  2    Tϵ  =  0.2031  +  6.362  ×    10    -  5    T    where C   p  is in J · mol -1 · K -1 , ρ is in 10 -8 Ω · m, and T is in K. Estimated inaccuracies of the measured properties are: 3 percent for heat capacity, 2 percent for electrical resistivity and 5 percent for hemispherical total emittance.
