At present, there are many metal powder materials that can be used for 3D printing. Due to the obvious spheroidization and agglomeration appearing in the forming process of single component metal powder, it is easy to cause sintering deformation and loose density. Therefore, multi-component metal...

...by reducing variations in gastric emptying rates and overall transit times. Pharmaceutical pellets are typically manufactured via extrusion spheronization, a three-step process introduced in the late 1960s, that results in spherical granulates roughly 1 mm in diameter. In this process, the powder is formed...

    Use of new, advanced methods of processing such as cladding, mechanical alloying, binder agglomeration, spheroidization , and formation of mechanical mixtures makes it possi- ble to produce from a single starting material powders having certain predetermined proper- ties and differing radically in particle … … opens up further possibilities for the formulation of thermal-sprayed coatings and prediction of their service characteristics.
  • Can Induction Plasma Technology be Nano-safe, "Green" and Energy Efficient?
    The building was designed to house two separate production halls (one for nano-powders synthesis and the other for powder spheroidization process). It had separate access to the infrastructure mechanical room for all services including cooling water, gases supply …
  • Hanford Laboratories Operation monthly activities report, October 1961
    Electron microscopy service for the month included examination of Al203 powder blown through a "plasmajet torch" to determine whether the powder particles, originally flat crystals, had been spheroidized. Examination by direct observation and by replica techniques showed that successful spheroidization was accomplished° .
