Abstract: The melting temperature of zirconium was measured at different pressures in the range from $1$ to $4000$ bar by pulsed current heating. The obtained pressure dependence of the melting temperature gives an estimate of the slope of the zirconium melting line of $624 K/GPa, which agrees well with the results of ab initio calculations.
