- Stanislas Sorel
Stanislas Sorel (1803,
Putanges ,France -1871-03-18 ,Paris ) was a Frenchengineer , 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 moltenzinc or by covering it with so-called "galvanic paint". This was the precursor of modernhot-dip galvanizing .In 1867, Sorel made a new form of
cement from a combination ofmagnesium oxide andmagnesium 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 artificialivory (e.g. for billiard-balls). It is stronger than the more usualPortland cement , but its poor water resistance makes it unsuitable for construction applications.References
