Abstract

Zinc oxide coated hollow glass beads were prepared by Chemical package method with ZnSO4٠7H2O,NH4HCO3 and hollow glass beads as raw materials, and they were characterized with UV/VIS spectrophotometer,SEM, and the heat insulation properties was detected by the homemade device. The experiment results shown that the near-infrared reflectivity of zinc oxide coated hollow glass beads was 45.1% better than the 12.5% of hollow glass beads, and it has good heat insulation properties.
