Ammonium paratungstate (APT), as a significant starting material for tungsten, which can be derived into the majority of tungsten products. Wolframite or scheelite (CaWO₄) concentrates are the two common materials are APT. There are two important steps in production of metallic tungsten from APT. The first step is thermal reduction of APT powder by heating at 400–900 °C, which leads to ammonia and water elimination as well as the crystallization of tungsten trioxide (W0₃). In the second step, an even higher temperature is required. WO₃ powder was heated under H₂ at 600–1100 °C, and metallic tungsten is then prepared.

Radiation protection tungsten alloy plate has strong and stable radiation shielding performance by absorbing X-ray, and γ-ray, etc. It is non-toxic, non-polluting, anti-wear and long-lasting. Also, it has good acid resistance, alkali resistance, and corrosion resistance. Therefore, it is mainly used in X-ray room, CT room of the hospital's radiology department, the dental clinic of the stomatological hospital, and the laboratories of some scientific research units, etc.

Tungsten alloy door is a new shielding door for medical applications such as X-ray department. In X-ray department, routine CT examination, MR examination interventional radiation diagnosis and treatment are undergoing. These departments use X-rays and other medical rays to assist diagnosis and treatment. Tungsten alloy protective door having strong absorption and shielding properties to X-rays and other radiation can play a good radiation shielding effect.

As a new medical X-ray protection material, W-Ni-Cu alloy (tungsten-based alloy), is lead-free, environmentally-friendly and non-magnetic, and has high density (~18.8g/cm3), strong ability to absorb high-energy rays. Also, it is machinable and weldable. Besides, it has properties of high hardness, high strength and low coefficient of thermal expansion. Therefore, W-Ni-Cu alloy is widely used in the field of medical radiation shielding sensitive to the magnetic environment.
