  • Patent number: 8048217
    Abstract: The invention relates to a powder composition based on a calcium/magnésium compound having formula (I), xCaA.(1?x)[yMgA+(1?y)MgO], in which A is a group ?(OH)2 or ?CO3 and x and y are mole fractions where 0<x=1 and 0=y=1, containing an amount of mineral solid flow agent that is less than 5 wt.-% of the composition, said agent being selected from the group containing vermiculite, perlite, diatomaceous earth and silica, in the form of particles having a size greater than 90 ?m.
