Making Metal Powder | PickPM

In this process, molten metal is separated into small droplets and rapidly solidified before the droplets come into contact with each other or with a solid surface. In principle, a thin stream of molten metal is disintegrated by subjecting it to the impact of high-energy jets of gas or liquid.

Cadmium Plating - Chem Processing Inc.

Cadmium Electroplating (Nadcap Accredited). Electroplated cadmium is a robust and versatile metallic coating. Cadmium is a soft white metal that, when plated onto steel, cast iron, malleable iron, copper, and powdered metal, functions as a "sacrificial coating," corroding before the substrate material.

Cadmium - Wikipedia

Cadmium occurs as a minor component in most zinc ores and is a byproduct of zinc production. Cadmium was used for a long time as a corrosion-resistant plating on steel, and cadmium compounds are used as red, orange and yellow pigments, to color glass, and to stabilize plastic.

Cadmium poisoning - Wikipedia

Cadmium is a naturally occurring toxic metal with common exposure in industrial workplaces, plant soils, and from smoking. Due to its low permissible exposure in humans, overexposure may occur even in situations where trace quantities of cadmium are found. Cadmium is used extensively in electroplating, although the nature of the operation does not generally lead to overexposure.

OSHA Guide: Cadmium

OSHA defines “objective data” as “information demonstrating that a particular product or material containing cadmium or a specific process, operation, or activity involving cadmium cannot release dust or fumes in concentrations at or above the action level even under the worst-case release conditions.”

What is Metal plating? A Look at the Metal Plating Process ...

The plating process is a manufacturing process in which a thin layer of metal coats a substrate. Metal plating provides many benefits to products made from metal and other materials. This can be achieved through electroplating, which requires an electric current, or through electroless plating, which is in autocatalytic chemical process.

Cadmium in Chocolate: Should You Be Worried? | Berkeley ...

Cadmium is naturally found in soil—a result, for example, of volcanic activity, for­est fires, and weathering of rocks—and is taken up by many plants, including cocoa plants. Soil can also be contaminated by “man-made” sources of cadmium, such as from the manufacturing of certain batteries and the use of phosphate fertilizers.
