Non-linear optical (NLO) crystal of p-Aminoazobenzene (p-AAZB) (or 4- aminoazobenzene) has been grown by slow evaporation solution technique using acetone as a solvent. The 0.1M of p-Aminoazobenzene (p-AAZB) was dissolved in 20ml of acetone and the beaker containing the solution was kept in a magnetic stirrer for 5 minutes. Then the beaker was taken from the magnetic stirrer and solution has been allowed for slow evaporation. A good quality optical crystal can be obtained after 10 days. The structural properties of the as grown title crystal were studied using X-Ray diffraction. The mechanical property of the crystal was examined by Vicker’s microhardness tester. Thermal properties and Dielectric properties were also been studied for grown crystal.
