Synthesis of γ-Ce₂S₃ colorant under low temperature and its coloring properties for PE and PVC

【摘要】 A series of cerium sulfides were successfully prepared using commercially available nanoscale CeO₂ as precursor, anhydrous Na₂CO₃ as dopants, CS₂ as sulfur source, under 600–800 oC, respectively. Properties of samples were investigated by means of X-ray diffraction（XRD）, scanning electron microscopy（SEM） and spectrophotometry. The results showed that corresponding γ-Ce₂S₃ with small size was obtained by using nanoscale CeO₂ as precursor; pure phase γ-Ce₂S₃ could be obtained under low temperature of 700 oC. Coloring properties of γ-Ce₂S₃ obtained under 800 oC were studied by researching γ-Ce₂S₃/PE and γ-Ce₂S₃/PVC composites, respectively. The results showed that satisfied coloring effects to PE and PVC were obtained by using 0.5 phr and 0.2 phr γ-Ce₂S₃, respectively.更多还原
