✦ Synopsis

The structural changes which occur when single crystals of a silicon carbide (6H) are heated in vacua, have been studied by using X-ray diffraction methods. The crystals were heated in an induction furnace for an hour to N 2280Β°C. This resulted in the formation of pseudomorphs which retained the morphology of the original Sic crystals but had a complicated structure which was made up of various stages in the development of a graphite lattice. A definite relation was found between the lattice of Sic and the structure of the resultant pseudomorph. The complex nature of the matrix is described and a possible mechanism of decomposition is suggested.

Silicon carbide (Sic) was chemical vapor deposited (CVD) onto a carbon fiber to investigate oxidation protection of the coating. This thin film of Sic was analyzed before and after argon and oxygen ion beam etching with core and valence band X-ray Photoelectron Spectroscopy (XPS). The valence band o

Polyimides have been extensively studied in view of their wide industrial applications. Adhesion to a substrate is essential for normal operation of devices. This problem is often solved by the use of an adhesion promoter on the surface of interest. A surface-sensitive technique such as XPS has prov
