Surik lead is a heavy fine-grained powder obtained by thermal oxidation litharge semi-finished, made of lead.


Minium - a pigment orange or orange-red color, ortoplyumbata composed of lead (Pb 3 O 4 ), lead monoxide (PbO), containing no impurities and having a high density.

 

Chemical formula: Pb 3 O 4 + PbO

The use of red lead.


Red lead oxide is used as pigment a very high quality orange and ground, and is used as a filler rubber and plastics.
Minium - strong oxidant, and these properties are due to the high antikorrozioynye paints based on it: it reacts with the iron, it oxidizes it to obtain a dense film of black oxide of iron (II), insoluble in water and impermeable to oxygen from the air. Lead oxide-coated steel construction does not rust even in seawater, but in most countries the production of red lead paint is very limited due to its toxicity.
More on volume of use is the use of lead oxide in glass (crystal, optical glass, radiation-resistant and protective glass).
A certain value it has as a desiccant, catalyst component "lead caulking."
Small in volume, but a very important sector of the use of lead oxide is to use it for protection against gamma radiation and for the production of other lead compounds: silica, carbonate, acetate and so on. A small but important red lead is in the manufacture of thermite explosives.
Surik also in the form of PbO (sometimes Pb 3 O

 

4 ) is a basic assay reagents, the precious metals are collected by melt ore mixture. The degree of solubility of gold and silver in lead, as a result of testing fusion, unlimited.
