Abstract :Generally, commercial product of calcium sulfate anhydrous insert ignore into journalissuearticles values(CaSO 4 ); is synthesized burning gypsum in kiln, in the process that the water is removed from gypsum crystallized by mixing CaCl 2 and Na 2 SO 4 in aqueous medium. It is possible to change gypsum properties by changing the parameters during crystallization. Also, the differentiation in the structures of the synthesized product can be possible with using additives during the crystallization. The changes in properties of these synthetically produced materials may be investigated instrumentally. This study examines change of surface fractal dimensions insert ignore into journalissuearticles values(D f ); of synthesized CaSO 4 anhydrate instrumentally. CaSO 4 .2H 2 O was synthesized by chemical precipitation method in the presence Polyinsert ignore into journalissuearticles values(Sodium 4-Styrene Sulphonate); and measured N 2 -physisorption measurements after burning. Fractal dimensions were determined using single N 2 -adsorption/desorption isotherms method. For Fractal dimension calculations, the Frenkel–Halsey–Hill insert ignore into journalissuearticles values(FHH); and the Neimark–Kiselev insert ignore into journalissuearticles values(NK); methods were used. Taguchi method has been used in evaluation of experimental design for optimization of D f values.
