Claims29
A porous proppant having a generally spherical shape with a particle diameter between 100 and 2,000 microns, median pore sizes between 1 and 50 microns, and a porosity between 10 and 70% of the total spherical volume.
A composition comprising a plurality of particles including silicon carbide, silicon nitride, or a combination thereof, forming a porous proppant having a generally spherical shape with a particle diameter between 100 and 2,000 microns, median pore sizes between 1 and 50 microns, and a porosity between 10 and 70% of the total spherical volume.
A method of making a porous proppant, comprising heating a composition including a carbon source and a silicon source between 10 and 70% porosity of the total proppant volume thereby forming a porous silicon carbide proppant.
