Production of Calcium Sulfide from reaction Carbon with Iraqi "gypsum"

850-900 . FT-IR .The study involve the use of carbon in the reduction of gypsum . The process was carred out by reacting the carbon with gypsum at different tempertures (850-900C).The amount of the reactants was vareid to get the best conditions for the conversionThe product from the treatment was analysed using FT-IR Also chemical analysies available is conductedThe prepared sample is compared with that of authentic sampleThe two samples were almost comparable
