sorel cement การใช้

Bischofite is used in the production of the industrial Sorel cement and synthetic carnallite.
Mixed with hydrated magnesium oxide, magnesium chloride forms a hard material called Sorel cement.
Sorel cement as it is known has been used for grindstones, tiles, artificial stone and even artificial ivory ( e . g . for billiard balls ).
Sorel cement was patented in 1867 by Frenchman Stanislas Sorel and was stronger than Portland cement but its poor water restive and corrosive qualities limited its use in building construction.
Sorel cement, invented in 1867, was marketed as an artificial ivory ), John Wesley Hyatt invented a composition material in 1869 called nitrocellulose for billiard balls ( US patent 50359, the first American patent for billiard balls ).
