Abstract: The present invention relates to a graphite target for X-ray tubes. In order to avoid the drawbacks of graphite carrier (1) targets due to transformation into carbide of the photo-emissive coating (3) by the carrier material, the invention provides for the formation of the intermediate layer (2) in these targets, in the shape of two sub-layers one of which (20), in contact with the carrier, is made of a refractory material which does not form a carbide (iridium for example), and the other of which (21) is made of another refractory material (tantalum for example), which prevents diffusion of carbon from the carrier into the emissive layer.
