Stanislas Sorel

From Wikipedia, the free encyclopedia

Stanislas Sorel (1803, Putanges, France - 1871-03-18, Paris) was a French engineer, born the son of a poor clock-maker.

Sorel filed a patent on 1837-05-10 for a "galvanic" method of protecting iron from rust by either coating it in a bath of molten zinc or by covering it with so-called "galvanic paint". This was the precursor of modern hot-dip galvanizing.

In 1867, Sorel made a new form of cement from a combination of magnesium oxide and magnesium chloride, which had a remarkable capacity to bond with and contain other materials. Sorel cement as it is known has been used for grindstones, tiles, artificial stone (cast stone), cast floors, and even artificial ivory (e.g. for billiard-balls). It is stronger than the more usual Portland cement, but its poor water resistance makes it unsuitable for construction applications.
