Abstract: 

Lithopon Pigment is mixture of zinc sulphide and barium sulphate that covering power is higher than white pigments such as zinc oxide and lead oxide. In order to synthesis of lithopon, first various portions of barium sulphate and active carbon were pressed in pellets forms and in final stage barium sulphate was pressed and reduced at 1150-1300°C in carbon bed for 2h. According to reaction formula of lithopon formation solutions of zinc sulphate and barium solphide were prepared. Reactor temperature was controlled in range of 70-90°C and soaked for 10-300 min. Investigation of phases was used by X-Ray defftactometry, element analysis by XRF and wet chemical analysis. Also the physical properties of pigment such as partical size distribution, specific surface area and powder density were measured by laser particle sizer, nitrogen gas absorption (BET method) and gas picnometry. In the final stage, optimized parameters of synthesis were investigated by technical raw materials.
