Effect of powder pretreatment on the application performance of tungsten crucible
The tungsten crucible samples were prepared by using the different tungsten powders, and the application simulation experiment was carried out in high temperature environment. The results show that, the jet grading pretreatment technology is an efficient process to improve the qualities of the tungs...

| description | The tungsten crucible samples were prepared by using the different tungsten powders, and the application simulation experiment was carried out in high temperature environment. The results show that, the jet grading pretreatment technology is an efficient process to improve the qualities of the tungsten crucible. The tungsten products with high density (18.770 g·cm−3) and high Vickers hardness (HV0.3 372.15) are prepared by jet grading, pressing, and sintering, using the tungsten powders with the Feller size of 3.0~3.5 μm as the raw materials. Meanwhile, the simulation application of tungsten crucibles is verified in the high temperature environment, which shows that the density and microstructure are stable. |
