Determination of Melting Point of NaCl and KCl Doped Sulphamic Acid Single Crystals by Capillary Method (CAT#: STEM-PPA-0039-YJL)

Introduction

Nonlinear optical (NLO) materials for second harmonic generation have received consistent attention for applications in the field of tele communications, optical computing, optical information processing, optical disk data storage, laser remote sensing, laser driven fusion and colour displays, in addition to their usual role of extending the limited frequency available from a laser. Among the non linear phenomena, frequency doubling, frequency mixing and electro optic modulations are important in the field of optical image storage and optical communications. Inorganic materials are widely used in these applications because of their high melting point, high mechanical strength and high degree of chemical inertness.
Sulphamic acid (SA) is a classical inorganic compound and an important industrial chemical with an annual manufacture of several kilotons. The pure, NaCl and KCl doped sulphamic acid single crystals have been grown by slow evaporation method. The solubility, density and melting point measurements were estimated.
