Abstract: The silicate of magnesium and of barium, strontium or calcium of the invention is characterized in that it is in the form of a suspension of solid crystallized particles in a liquid phase, said particles having a mean size between 0.1 μm and 1 μm. It is prepared by spray-drying a liquid mixture comprising compounds of magnesium, of silicium and of at least one first element chosen from barium, strontium and calcium, by submitting the dried mixture to a first calcination in air and to a second calcination in a reducing atmosphere and by wet milling the calcined mixture.
