  • Process for producing a stabilized magnesium hydroxide slurry
    Patent number: 9890054
    Abstract: The present disclosure provides stable magnesium hydroxide slurry compositions and methods for producing stable magnesium hydroxide slurry compositions. The stable magnesium hydroxide slurries of the disclosure comprise magnesium hydroxide at about 50 to about 70% solids by weight in the slurry, a viscosity of less than about 1000 centipoise, and a 7-day pour test of 90% or greater.
    Type: Grant
    Filed: February 4, 2016
    Date of Patent: February 13, 2018
    Assignee: Martin Marietta Magnesia Specialties, LLC
    Inventors: Aileen Gibson, Lemuel Granada, Jr., Mark Wajer

  • Flame-retardant magnesium hydroxide compositions and associated methods of manufacture and use
    Patent number: 7514489
    Abstract: The invention provides a submicron magnesium hydroxide particulate composition comprising a first distribution of magnesium hydroxide particles having a D50 of no more than about 0.30 ?m, a D90 of no more than about 1.5 ?m, and a BET surface area of at least about 35 m2/g, which can be used as a flame-retardant additive for synthetic polymers, optionally in combination with other flame-retardant additives such as nanoclays and larger-sized magnesium hydroxide particulate compositions. Polymeric resins comprising the submicron magnesium hydroxide particles and methods of manufacturing submicron magnesium hydroxide particles are also provided.
