Avrasya Nükleer Bilimler ve Uygulamaları Konferansı : 23-27 Ekim 2000. İzmir, Türkiye.In this study, pure urania (U02) and urania-gadolinia (U02-Gd20 3), 5 and 10% Gd20 3 fuels were first produced by sol-gel (solution-gelation) ceramic fuel preparation technique. The solgel micro sphere pelletization technique is a recent and advanced concept of fabrication of fuel pellets that is because it ensures excellent micro homogeneity in the prepared pellets. The sintered fuel pellets were then coated with boron carbide (B4C). This coating is performed through chemical vapor deposition (CVD). The chemical vapor deposition consists of essentially of reducing or decomposing a volatile compound of coating material upon a heat surface on the size of micron dimensions. In this work, boron carbide was deposited in a silica glass. Afterwards, the XRD spectra of B4C coatings were taken by using B4C on the surface of the silica glass. The spectra results were in agreement with the ones in the literature. The experiments showed that the composition of the coating changed with deposition temperature. There was boron rich coating in the low experimental temperatures while the coating in the high temperatures was found to be rich in the carbon content. The morphology and the thickness of the coating have been investigated by using Scanning Electron Microscopy (SEM). The investigation under the SEM revealed a fine grained and some rod like layered boron carbide coatings.enginfo:eu-repo/semantics/openAccessSEM picturesSEM resimleriXRD spectraXRD spektrumlarıU02 fuelU02 yakıtıUO2-GCİ2O3 fuelUO2-GCİ2O3 yakıtıScanning Electron MicroscopyTaramalı Elektron MikroskobuUranium dioxideUranyum dioksitGadolinium oxideGadolinyum oksitBoron carbideBor karbürNuclear fuelsNükleer yakıtlarB4CCVDconferenceObject259265
