Scientific paper

Some physical, chemical, and optical properties of mixed oxide grain material are discussed, and the formation of such dust is examined. Surface chemistry on these grains may be responsible for the depletion of elements and for the formation of molecules such as H2CO in diffuse clouds. Spectra of mixed oxide grains yield features at 9.6 and 18 microns, together with a broad band at 4.6 permicrons.
