PURPOSE: To coat on an oxide surface layer a composition, which can maintain good adhesion characteristics and emmisivity of thermal radiation obtainable in the past with a common coating method by making a phase, which contains silicon oxide and is evenly fused, of oxide coating on an X-ray tube anode. CONSTITUTION: Oxide coating contains oxide composition used in the past namely such as for instance zirconium oxide, calcium oxide and titanium oxide with a ratio of 70:10:20 respectively. At the same time, oxide mixture can contain oxide aluminum for 10% by weight in order to increase or decrease a fusing temperature. In addition, a phase which contains silicon dioxide for 1-20% by weight and is evenly fused is made of the oxide coating.
