MECHANICAL AND DIELECTRIC STUDIES ON BIS- THIOUREA CADMIUM CHLORIDE (BTCC) CRYSTAL BY SLOW EVAPORATION TECHNIQUE

Abstract

Bis-Thiourea Cadmium Chloride is abbreviated as (BTCC) were grown from aqueous solution by low temperature solution growth technique. Good optical quality
single crystal of dimensions 12 × 7× 2.15 mm3 was harvested in a period of two weeks. Single XRD analysis confirmed that the pure crystal is in orthorhombic structure with lattice parameters a=5.798(Å), b=6.456(Å), c=13.079(Å). FTIR spectroscopy study reveals the presence of functional groups present in the grown crystal. Microhardness studies were carried out using Vickers pyramidal indentation method at room temperature shows that the grown crystal belongs to soft material category. Dielectric studies are done on the grown BTCC crystal
