GROWTH AND MICROHARDNESS STUDIES OF MELT-GROWN LEAD (II) CHLORIDE SINGLE CRYSTALS
Published 1990 · Chemistry
In the present work, lead (II) chloride material is purified by directional solidification and single crystals of PbCl2 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 K1 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.
