  • Calco-magnesian aqueous suspension and method for the production thereof
    Patent number: 8206680
    Abstract: Calco-magnesian aqueous suspension having particles of solid matter with, before being put into suspension, a specific surface area, calculated according to the BET method, which is less than or equal to 10 m2/g, and its method of preparation. Such an aqueous suspension of calco-magnesian solid matter can achieve a very low viscosity, making it possible to greatly increase the solid matter concentration of the suspension, or again to reduce the size of the particles in suspension, thus obtaining a concentrated and reactive milk of lime.
