摘要：

A novel spouted-bed coating process was developed, in which supercritical fluid solutions of coating material were expanded into the bed. The mechanism of film coating by the rapid expansion of supercritical fluid solutions was studied. The coating was found to take place in the vicinity of the nozzle.
