    Abstract: Aerogel particles having a mean particle size less than 1 micron, products containing the same, processes of making the same, and uses thereof are described. A process of making the particle is also described wherein starting aerogel particles are homogenized or wet milled. The starting aerogel particles can be surface treated during the milling process to prevent agglomeration or aggregation. The aerogel particles can be used in a variety of products and applications.
