%X La0.8Sr0.2MnO3 smart thermal control coating was obtained by coating technology using La0.8Sr0.2MnO3 powder as base material and Al(H2PO4)3 as binder, respectively. The La0.8Sr0.2MnO3 powders were prepared by solid state reaction. La0.8Sr0.2MnO3 powders were characterized by XRD and EDS. The variable thermal emittance of La0.8Sr0.2MnO3 thermal control coating was measured at the temperature range of ―100  o 100  y the steady―state emissometer. In addition, the solar absorptance of as―prepared coating was surveyed. The results showed that homogeneous, micro―sized La0.8Sr0.2MnO3 particle can be obtained through heat treatment at 1200  or three times. The variation of the thermal emittance from ―100  o 100  f as―prepared coating by coating technology could be more than 0.3, which is close to that of La0.8Sr0.2MnO3 ceramic tile. This kind of smart thermal control coating is a promising candidate material in satellite for active thermal control technology.
