Abstract

A vertical Bridgemann Stockbarger crystal growth workstation was designed and fabricated indigenously. It consisted of a single zone z-axis oriented resistively heated furnace capable of reaching 400°C. A ceramic insulation blanket is arranged around the concentric vicinity in order to insulate to perfection. Naphthalene is an organic compound with formula C10H8. As an aromatic hydrocarbon, naphthalene's structure consists of a fused pair of benzene rings. Naphthalenes substituted with combinations of strongly electron-donating functional groups, such as alcohols and amines, and strongly electron-withdrawing groups, especially sulfonic acids, are intermediates in the preparation of many synthetic dyes. They are also used as dispersants in synthetic and natural rubbers, and as tanning agents (syntans) in leather industries, agricultural formulations (dispersants for pesticides), dyes and as a dispersant in lead–acid battery plates. Napthalene also has good luminescence, fluorescence and dielectric properties. Crystals of Napthalene were grown by Bridgmann-Stockbarger technique and were characterized for their structural, optical and spectroscopic properties
