SEM-EDXA analysis showed that the surfaces of granular SiC ceramic obtained at 1,650[degrees]C contained about equal amounts of carbon and silicon and less than 10 percent oxygen.
The thin film deposit was strongly bound to the wood cell wall and remained practically intact even after water leaching and exposure to UV radiation as indicated by the SEM-EDXA results.
