Fine Powders of Metals Ceramics and Polymers

Particle sizes range from 0.1 micron (e.g., alumina) to 850 microns (e.g., iridium). In addition to pure metals, alloys, ceramics, polymers, and compounds, a number of custom-made alloys are available in powder form.

Various techniques can be employed for the manufacture of these materials, the composition of which can often be specified to meet individual requirements.

Applications for powders are wide-ranging, with benefits derived from the form as well as the general properties of the specific material. For example, the large surface area to volume ratio makes certain metal powders excellent for use as catalysts.

Fine powder of certain materials is also easy to dissolve in a solvent for casting thin films. In addition, powders can be used to produce porous structures by sintering. Goodfellow technical specialists are available to discuss the full range of applications or answer specific questions.
