When the CT tube is working, the anode target produces X-rays under the bombardment of high-energy electron beams, but the energy conversion efficiency is very low. Only about 1% of the energy is converted into X-ray energy, and the remaining 99% of the energy is converted into heat energy. The local temperature can be as high as 2600°C. Therefore, the rotating anode target needs to have the characteristics of high high temperature strength, good thermal shock resistance, and fast heat dissipation. Therefore, the density of the target material, the content of alloy impurity elements, and the brazing bonding strength of graphite and molybdenum alloys affect the service life of the target. Key factor.

Tungsten heating devices will become brittle after being recrystallized after being used at high temperature, and will easily break under impact or vibration. Compared with tungsten, rhenium has a higher recrystallization temperature, and the recrystallized rhenium is not a brittle material, but its strength is reduced. As a non-stressed heating device, it still has good working ability and has the best high temperature stability. High creep strength. Therefore, rhenium is used to manufacture MOCVD heating devices. It is the most appropriate choice in consideration of performance and cost. No other material can replace it.

Rhenium is a sparse, refractory metal. Scattered means that the content of rhenium in the earth's crust is scarce and dispersed, and refractory means that the melting point of rhenium metal is extremely high, with a melting point of 3180°C, second only to tungsten, ranking second among all metals. Because of its compound's excellent properties such as catalytic activity, high temperature resistance, and corrosion resistance, it is mainly used in petroleum smelting catalysts, thermoelectric superalloys, electronic tube structural materials, special aerospace alloys, and environmental protection.
