  • Publication number: 20030141485
    Abstract: A long term stabilized magnesium hydroxide suspension which can be used for covering pellets of several materials in order to avoid the agglomeration of a plurality of pellets when stored or subjected to a heat treatment and which can be stored for at least three months without substantial agitation and without experiencing substantial settlement and solid hard substrate formation, comprising a solid content of about 51% to 61%; a water content of about 39% to 49%; a viscosity of about 500 to 1,500 cp.; an average particle size of about 1 to 2.5 microns; a Mg(OH)2 content of about 50% to 60%; an equivalent magnesium oxide content of 34% to 42%; including an adherent compound at a concentration of at least 30% in an amount of 0.

  • Patent number: 5811069
    Abstract: A long term stabilized magnesium hydroxide suspension which can be stored for at least six months without substantial agitation and without undergo substantial settlement nor solid hard substrate formation, comprising a solid content of about 51% to 62%; a water content of about 38% to 49%; a viscosity of about 50 to 400 cp.; an average particle size of about 1 to 2.5 microns; a Mg(OH).sub.2 content of about 50% to 60%; an equivalent magnesium oxide content of 34% to 42%; and including an anionic polyelectrolyte as a dispersant agent, and which is obtained by washing, filtering and repulping magnesium hydroxide solids to obtain agglomerated solid particles, dispersing the agglomerated solid particles by comminution in a dispersing equipment, to reduce the particle size providing a dispersed product, grinding the dispersed product to additionally reduce the particle size to about 2 microns; and adding an anionic polyelectrolyte at a concentration of at least 25%, in an amount of about 0.5 to 1.
