| Abstract: | Mixed crystals of various proportions of urea thiourea were grown by slow evaporation of aqueous solution at room temperature.
The bright and transparent crystals obtained were characterized using thermogravimetry–differential thermal analysis (TG–DTA)
and FTIR spectroscopic analyses. A fitting decomposition pattern for the title compound was formulated on the TG curve which
shows a two-stage mass loss between 175 and 750 °C. In this temperature range, DTA curves show exothermic peaks supporting
the formulated decomposition pattern. The FTIR spectra show the characteristic absorption, vibration frequencies due to urea
thiourea. Detailed structural analysis of the compound is under progress. |
