In the present work, lead (II) chloride material is purified by directional solidification and single crystals of PbCl 2 are grown by vertical Bridgman technique employing double zone furnace. The growth conditions and the problems overcome are discussed. The grown crystals of pure and K + ‐doped crystals are cleaved and subjected to microindentation tests. The validity of Kick's relation is checked, the value of K 1 the standard hardness number and n the work‐hardening coefficient are discussed. The microhardness behaviour of pure and K + ‐doped lead(II) chloride have been compared.
