Beryllium is an element of the second main group of the second period, with an atomic number of 4 and an element symbol of Be. It is a gray-white alkaline earth metal. Beryllium and its compounds are highly toxic. Beryllium is soluble in both acid and alkali and is an amphoteric metal. The density of beryllium is similar to that of magnesium, and its rigidity is comparable to that of tungsten. Its melting point is 1285 ℃, and it has a very strong thermal neutron scattering ability. When the temperature changes by hundreds of degrees, the beryllium parts can still maintain their original size.
Application Advantages of Beryllium X-Ray Transparent Window
1. Transmission
Among all metals, beryllium has the strongest ability to transmit X-rays. Metal beryllium is the lightest (smallest atomic number) and most stable metal, so it has little shielding effect on X-rays.
2. Machinability
The thermal expansion coefficient of beryllium is comparable to that of stainless steel and Ni-Co alloy, so it has good welding performance and good thermal conductivity. At the same time, metal beryllium can be made very thin, and the thinnest window is only tens of microns thick. The temperature of the X-ray tube is very high when it is working, and metal beryllium can insulate the high temperature.
3. Corrosion resistance
Beryllium can react with oxygen at room temperature to form a thin protective oxide film on its surface, so it is very stable even when it is red hot in the air and is insoluble in water. However, it is slightly soluble in hot water and can be dissolved in dilute hydrochloric acid, dilute sulfuric acid, and potassium hydroxide solution to release hydrogen. Therefore, when using it, you should also pay attention to whether there is an acidic atmosphere in the use environment. If so, you need to cover the beryllium window with a protective film.
Be is the material that absorbs the least X-rays, especially soft X-rays, and has a certain mechanical strength, so it is currently the best window material. The thinner the process of the Beryllium Window, the smaller its mechanical strength, the more difficult the processing and manufacturing process, and the higher the price.
In short, as the window material of the X-ray tube, the High Purity Beryllium Window can not only seal the light tube but also maintain the vacuum inside the light tube. At the same time, the beryllium window can also filter low-performance X-rays to a certain extent. Our company generally accepts customized services for beryllium windows and has advanced production equipment and technicians, so you can order with confidence.
