【Abstract】 CuO?ZnO?Fe 2O 3?MgO nanometer particles were synthesized by precipitation method,and metal salt?Na 2CO 3?NaOH as the starting materials.These nanometer particles were characterized by XRD?IR?TEM.The comparation effects between nanometer matal oxides and micron matal oxides on smoke suppression in PVC combustion,the results indicate that nanometer matal oxides are much better than micron ones on the same conditions.更多还原
