Medical tungsten alloy radiation shield has a wide application in radiotherapy, medical imaging, and radioactive tracing, etc. More details, please visit: http://www.tungsten-alloy.com/tungsten-alloy-radiation-shielding.html Applications of Medical Tungsten Alloy Radiation Shield 1. Radiotherapy – Treat malignant tumors with one or more ionizing radiations. Radiation shields (collimators, multi-leaf, etc.) on radiotherapy equipment such as medical electronic linear accelerators and cobalt-60 treatment machines are made of W-Ni-Fe alloy. Tungsten alloy shields can reduce the particle beam, so that the particle beam is irradiated in…

Tungsten anti-scatter grid is a new type of radiation shield that has excellent ionizing radiation absorption characteristics, which meets the radiation protection requirements of CT scanner and other CT imaging equipment. More details, please visit: http://www.tungsten-alloy.com/tungsten-alloy-radiation-shielding.html Tungsten anti-scatter grid has higher density than lead anti-scatter grid, so it has higher absorption of scattering X-ray, thereby enhancing the quality of CT images and protecting patients from excess scattered radiation. Also, it is durable with high hardness, high strength, high temperature and…

Tungsten alloy anti-scatter grid is applied to a CT device to absorb harmful scattered radiation, thereby significantly improving the quality of CT imaging and reducing the radiation dose received by patients. This is because the selected high-quality tungsten alloy raw material has strong radiation absorption and shielding ability. Studies have shown that with the same thickness, the radiation shielding ability of tungsten alloy is more than 1.7 times that of lead. And the difference between the two materials’ ability to…

Medical tungsten radiation shielding material is a class of radiation protective material that has high radiation shielding performance and environmental protection characteristics. There are two type of medical tungsten radiation shielding materials – tungsten alloy materials and tungsten polymer materials. And they are the first choice materials for manufacturing medical radiation shields for different applications. More details, please visit: http://www.tungsten-alloy.com/tungsten-alloy-radiation-shielding.html Tungsten alloy is mainly composed of more than 90% tungsten powder, adding with other metal powders such as nickel, iron…

Tungsten alloy sheet is applied for a CT detector (X-ray detector) to shield X-ray radiation. Tungsten alloy sheet is made of W-Ni-Fe alloy – an alloy composed of a small amount of nickel, iron and other alloying elements using tungsten as the matrix, and has a high density (~18.8g/cm3) and a high energy ray absorption capacity (1/3 higher radiation absorption coefficient than lead), so that it is widely used in the radiation protection and guidance of CT detectors to provide…

Single-crystal ammonium paratungstate has a wide application as it has good fluidity, excellent tensile resistance and fracture resistance. And therefore single-crystal APT is used to prepare tungsten powder, high-performance tungsten materials such as tungsten wire, weights, armor bombs, micro-drills, and CNC blades, etc. More details, please visit: http://ammonium-paratungstate.com/index.html Applications of Single-crystal Ammonium Paratungstate Studies have shown that tungsten powder can be prepared using single-crystal ammonium paratungstate as a raw material by calcination – hydrogen reduction. With good fluidity, the prepared…

What is the solubility of ammonium paratungstate? The more common question is – “Is ammonium paratungstate soluble in water?” or “Is APT soluble in water?” More details, please visit: http://ammonium-paratungstate.com/index.html Solubility of Ammonium Paratungstate 1. APT is slightly soluble in water, and its solubility in water is less than 2% at 20 °C. 2. APT is insoluble in alcohol. 3. Heating APT to 220-280 °C, it loses part of the ammonia and crystal water, to be converted into ammonium metatungstate…

How to prepare high-purity ammonium paratungstate? The researchers proposed a method for preparing high-purity APT. This method improves the quality of ammonium paratungstate and reduces the production cost of high-purity APT. More details, please visit: http://ammonium-paratungstate.com/index.html A Preparation Method of High-purity Ammonium Paratungstate Step One: Put APT into the feed bin and send it into the rotary furnace through the screw feeder at a constant speed. Control the calcination temperature and atmosphere in the rotary furnace. The feed volume is…

One of the applications of ammonium paratungstate is – to prepare submicron spherical tungsten powder. For example, some researchers have prepared submicron spherical W powder using ammonium paratungstate as a raw material through the circulatory oxidization-reduction method. More details, please visit: http://ammonium-paratungstate.com/index.html Ammonium Paratungstate Application – To Prepare Submicron Spherical Tungsten Powder Through Circulatory Oxidization-Reduction Method Violet tungsten oxide was prepared with pure ammonium paratungstate in argon gas. Tungsten powder was obtained from violet tungsten oxide through deoxidation in hydrogen…

Ammonium paratungstate (APT), a white crystalline salt, is well-known as the most important raw material for producing all other tungsten products, so the production methods of APT attract much attention. More details, please visit: http://ammonium-paratungstate.com/index.html Production Methods of Ammonium Paratungstate 1.From tungsten ores. Tungsten ores, which are typically oxides, are digested in base to give solutions of tungstate together with many contaminating species. This crude extract is acidified and treated with sulfide to separate molybdenum trisulfide. Upon further acidification APT…
