Very fine powder can be combustible. [2] Ferrophosphorus is used in metallurgy as a source of phosphorus for alloying, for deoxidizing the melt and for removal of unwanted compounds into slag. Ferrophosphorus is a byproduct of phosphorus production in submerged-arc furnaces from apatites, by their reduction with carbon. It is formed from the ...

In these applications, the phosphor is directly added to the plastic used to mold the toys, or mixed with a binder for use as paints. ZnS:Cu phosphor is used in glow-in-the-dark cosmetic creams frequently used for Halloween make-ups. Generally, the persistence of the phosphor increases as the wavelength increases.
A similar process uses a borohydride reducing agent, yielding a nickel-boron coating instead. Unlike electroplating , processes in general do not require passing an electric current through the bath and the substrate; the reduction of the metal cations in solution to metallic is achieved by purely chemical means, through an autocatalytic reaction.
