[Know Tungsten] Tungsten Alloy X-Ray and γ-Ray Shielding

Both X-rays and γ-rays have high energy and can penetrate the human body for imaging or kill cancer cells. They are gradually being widely used in medical imaging diagnosis and radiotherapy. Only high-performance materials that can effectively control the range of rays, reduce the damage of rays to other normal parts of the patient, and prevent the surrounding environment from being affected by rays can be widely used.

The tungsten alloy X-ray and gamma-ray shielding parts we produce have a density ranging from 17g/cc to 18.5g/cc. They are often used in CT, linear accelerator, PET, nuclear medicine, gamma cameras and other fields, and can provide the best radiation protection. With Beam Guidance, we not only provide raw materials and finished parts, but also provide a full range of solutions.

【Know Tungsten】What is Tungstic Acid?

Tungstic acid is yellow and shiny flaky crystal or crystalline powder, soluble in water, insoluble in ethanol, and slightly soluble in ammonia. Weathering in the air. When heated to 100°C, it loses crystal water and becomes anhydrous. It reacts with strong acids (except hydrofluoric acid) to form water-insoluble yellow tungstic acid. It reacts with phosphoric acid or phosphate to form phosphotungstic heteropoly acid complex. It reacts with organic acids such as tartaric acid, citric acid, and oxalic acid to form corresponding organic acid complexes. compound.


Tungsten trioxide reacts with sodium hydroxide, or tungsten concentrate and sodium hydroxide are pressure-cooked to generate a tungstic acid solution. After refining, filtration, ion exchange and other processes, the impurities are separated, and then evaporated and crystallized to obtain a tungstic acid product.

The uses of tungstic acid include the following aspects:

1. Tungstic acid is an important chemical raw material that can be used to manufacture metal tungsten, tungsten wire, tungstate, etc.

2. Due to the rich color of tungstic acid, it can be used as mordant, pigment, dye and ink.

3. Tungstic acid is used as a fabric weighting agent or fabric auxiliary in the textile industry. A mixture of tungstic acid, ammonium sulfate, ammonium phosphate, etc. can be used to make fibers fireproof and waterproof. This fiber can be used to make fireproof rayon and rayon. Can also be used for leather tanning.

4. Used for electroplating coating anti-corrosion.

5. Used as a co-solvent to introduce enamel color materials, which can reduce the firing temperature and complement the color.

6. Used in the petroleum industry and the manufacturing of aviation and aerospace materials.
