The invention provides a plurality of polymeric particles embedded with silicate that include gas-filled polymeric microelements. The gas-filled polymeric microelements have a shell and a density of 5 g/liter to 200 g/liter. The shell having an outer surface and a diameter of 5 μm to 200 μm with silicate particles embedded in the polymer. The silicate particles have an average particle size of 0.01 to 3 μm. The silicate-containing regions are spaced to coat less than 50 percent of the outer surface of the polymeric microelements; and less than 0.1 weight percent total of the polymeric microelements is associated with i) silicate particles having a particle size of greater than 5 μm; ii) silicate-containing regions covering greater than 50 percent of the outer surface of the polymeric microelements; and iii) polymeric micro elements agglomerated with silicate particles to an average cluster size of greater than 120 μm.
