ISSN: 2278 – 1323 International Journal of Advanced Research in Computer Engineering & Technology Volume 1, Issue 4, June 2012 Behavior of mixture of Sulfamic Acid and Sodium Chloride Dr. Rita A. Gharde1*, Divakar T. Chunarkar 1, Department of Physics, Mumbai University, Kalina (Santacruz), Mumbai – 400 008. (India) E-mail ID: gharde.rita@gmail.com, divakar.chunarkar@rediffmail.comAbstract:- analyses a revealed the diffraction pattern for sulfamic acid and sodium chloride crystal have A mono crystal known as single crystal almost the same set of peaks [2]. Our study alsoof sulfamic acid (H2NSO3H) and sodium chloride found that good quality crystal growth material(NaCl) is an inorganic non-linear optical material can only be obtained into doping range this werewas grown by slow evaporation solution growth suggest a new approach for using material fortechnique. In this work, we are interested in the crystal growth material. It is found that thegrowing single crystal for non-linear optical dielectric constant of the material is enhancedapplication. Beside this, we are trying to develop due to doping of Sodium Chloride so Sulfamicnew material that, have specific thermo Acid. This can be used in many application.

Single crystal are freeform internal boundaries. They give rise tocharacteristic x-ray diffraction pattern. A singlecrystal can be as big as few centimeter or it maybe as small as fraction as a centimeter suchthat its feature can not be seen by necked eye.Such crystal is called mono crystal.

FTIR Spectrum of mixture sampleobtained by the powder XRD analysis are inaccordance with the single crystal XRD data.The calculated plans satisfy the generalreflection condition of space group observedform the structure determination of the crystal.In previous study the single crystal XRD revealsthat the Sulfamic Acid crystal belongs toorthorhombic structure. From this spectrumproved to be highly useful in determiningstructure and dimension of crystal as well as inthe study of number of properties of x-ray issame as like a previous sulfamic acid samplethe value of 0 for the first order reflection formthe three faces of doping crystal are found [7]. The range of slpfamic acid sample and dopingWe conclude that there is not much change in sample is nearly same. The FTIR spectra of thethe molecular structure of sulfamic acid due to crystal were recorded in the sulfamic acid anddoping of sodium chloride.

It is an important material for possible application the single crystal FTIR show that, the doping crystal belongs to Centro symmetric space group [9]. Melting Point :- We studied the melting point of grown doping crystal by capillary melting method. Crush doped crystal sample and filled in the capillary tube and measure the melting point with the help of the help of the melting point instrument. We found that it gives higher heat energy as compared to sulfamic acid single crystal. Such type of material are used in the photo electricFTIR :- effect.

In this doping crystal we found that, Na being highly electro positive removes H2 atom from sulfamic acid and form Na salt of Sulfamic acid. Hence no effect on the crystal. Due to Na+ is more electropositive then H+ and hence doping sample formed is more 232 All Rights Reserved © 2012 IJARCET
