Calcium carbonate and zinc hydroxystannate-coated calcium carbonate (ZHSCC) was prepared by biominetic synthesis in template of sodium dodecyl benzene sulfonate (SDBS), and was characterized by XRD, SEM and TG/DSC, moreover, the flame retardant property of ZHSCC in PVC was studed by LOI. The XRD analysis clearly showed the diffraction peaks of zinc hydroxystannate (ZHS) in ZHSCC and calcite crystal structure of calcium carbonate. The TG/DSC and SEM results showed that ZHSCC product was roughly spherical with the size of was about 4 μ. The LOI of PVC/ZHSCC blend increased 5.5 units which showed that ZHSCC had a good flame retardant efficiency for PVC.
