GRAFMETAL also offers fine silver powder (dust), consisting of about 99% silver. The particle size is about 5 μm and smaller. The powder is fine enough to be spread on a surface. The dust will find many applications in making of conductive adhesives and paints, metal clays for firing and in manufacturing of conductive paths for electronic circuits or photovoltaic cells. The black line seen in the microscope images is a 30 μm wide marker.
We are the manufacturer, we have the ability to customize the product.
