We have developed a variable-emittance radiator device, made of thin, and fight ceramic tiles, for thermal control applications on spacecraft. The ceramic material used is La1-xSrMnO3 with a perovskite structure, which shows a phase transition fro...

Two types of thermal control materials developed for space use are described. These new materials use a variable emittance radiator called the smart radiation device (SRD). The SRDs are based on La0.825Sr0.175MnO3 and La0.7Ca0.3MnO3 and comprise a...

A variable-emittance radiator device, made of thin and light ceramic tiles, has been developed for thermal control applications on spacecraft. The ceramic material used is La1-xSrxMnO3 with a perovskite structure, and shows a phase transition from...
Variable-emittance radiators based on the metal-insulator transition of (La,Sr)MnO3 thin films have been developed. The emittance property of the films was evaluated from infrared reflectance spectra; that is, the (La,Sr)MnO3 thin films show low e...
