Tungsten Crucible 685

Tungsten crucible may be manufactured by the cold isostatic pressing – sintering method with the size of 301mm×350mm. The density and oxygen content of the samples collected from the wall and bottom of the tungsten crucible were analyzed to study the density uniformity of the tungsten crucible. The density of the crucible is 18.22 g/cm3. And it decreased about 0.1g/cm3 after machining. The density of the tungsten crucible bottom is relatively lower. The lowest density exists in the arc corner,…

Tungsten Flux 656

Tungsten flux is tungsten granule, which is also called tungsten accelerator. It can be used as a fluxing agent for the determination of carbon and sulfur. In the determination of C&S by burning method, some fluxes need to be added into the sample to fully oxidize carbon and sulfur. The flux is to provide the sample with heat to oxidize, change the melting characteristics, stabilize the combustion process, and cover the sample to prevent splashing. Choosing an appropriate fluxing agent…

Tungsten Ball 321

Tungsten ball may be divided into pure tungsten ball, tungsten alloy ball and tungsten carbide ball. Tungsten Ball with a High-velocity Penetrating into a Medium-thick Steel Plate A 57.5/14.5mm two-stage light-gas gun was used to launch 7mm diameter tungsten ball projectiles penetrating into an A3 steel plate with a thickness of 20mm. The projectiles impacted the target with a normal incidence at a velocity of 1.900 to 2.350km/s. A total of seven trials were conducted and none of them penetrated…

Rotating W-Mo Composite Target 270

Rotating W-Mo composite target is cylindrical, which may be produced using hot isostatic pressing technology. The density of the obtained target is close to its theoretical density. And its structure uniformity and purity are excellent. In addition, the utilization of this W-Mo composite target is much greater than that of flat tungsten-molybdenum target. There are some main factors to measure the quality of this composite target: purity, density, grain size and distribution. The W-Mo composite target may be produced by…

X-ray Machine Tungsten Target 320

X-ray machine tungsten target?is referred as to the tungsten target that is used in X-ray machines. The X-ray machine is an important medical device in radiology department for breast examination. Great advances have recently been made in the production of X-rays, chiefly by the employment of very heavy currents. The exposures necessary for producing radiographs of the thorax have been reduced from minutes to fractions of a second. To make this possible, much attention has been devoted to the target…

High-purity Tungsten Target 309

High-purity tungsten target is mainly prepared by hot pressing, hot isostatic pressing and so on. And tungsten target with high purity and high density may be prepared by intermediate frequency sintering and pressure processing, but its grain size and grain homogeneity are not very well compared with the tungsten target produced by hot isostatic pressing. High purity tungsten target has the characteristics of high temperature stability, high electron transfer resistance and high electron emission coefficient so that it is widely…
