摘要： A high thermal emittance coating for an x-ray tube anode target which permits broader application parameters and a stable coating. The coating is composed of Al.sub.2 O.sub.3 present in an amount of 50% to 80% by weight and ZrO.sub.2 or La.sub.2 O.sub.3 and TiO.sub.2 present in an amount of 50% to 20% by weight with the TiO.sub.2 and ZrO.sub.2 or La.sub.2 O.sub.3 being present in a ratio in the range of 1:1 to 10:1. A preferable coating is composed of about 80% by weight of Al.sub.2 O.sub.3 and 20% by weight of TiO.sub.2 and ZrO.sub.2.

摘要： An X-ray tube anode which is composed of a refractory metal having a focal track thereon with the refractory metal including tantalum, hafnium, zirconium and carbon in a minor amount and molybdenum in a major amount. The anode has improved high temperature properties and fabricability. It can be utilized alone or in combination with the usual graphite portion.
