What is ammonium metatungstate? Ammonium metatungstate, AMT for short, is a white or slightly yellow crystal powder that is soluble in water and insoluble in ethanol. AMT is an important intermediate compounds of tungsten hydrometallurgical process. Its chemical formula is (NH4) 6H2W12O40·XH2O, molecular formula is H8N2O4W, and molecular weight is 283.9145.

Tungsten alloy radiation shielding door is a protective door made using tungsten alloy plate as a shielding part for applications in the CT room. Tungsten alloy radiation shielding door has a higher radiation shielding effect than the traditional lead door, and is environmentally friendly and non-toxic. Also, it will not pollute the environment, and can be recycled, so tungsten alloy door is the most popular lead-free radiation protection door.

Tungsten alloy shield is a new type of lead-free shield with excellent shielding performance to X-rays so that it is mainly applied for mobile CT machine. Moreover, it is environmentally friendly and non-toxic, and will not affect the water, soil and air in the environment. It has been reported that mobile CT machine is used in mobile cabin hospitals because of its flexibility, efficiency and convenience, and patients can be examined nearby. A chest CT takes less than 3 minutes. The application of this highly sophisticated equipment has played an important role in satisfying first-line treatment.

Tungsten alloy sheet is necessary for radiation protection of CT room. What is the most important device in the CT room? CT scanner. While there are X-rays. And there is a risk of carcinogenesis. Therefore, there are radiations shielding parts in CT rooms and on CT scanners such as tungsten alloy plates and tungsten alloy tubes.
