发明名称 SPHERICAL CORUNDUM PARTICLES, BASED ON FUSED ALUMINIUM OXIDE AND A METHOD FOR PRODUCING SAID PARTICLES
摘要 <p>An embodiment consistent with the present invention is a high strength proppant comprising an electrofused pellet. In another embodiment, a high strength proppant comprises a substantially solid and substantially spherical pellet produced by electrofusion of at least one metal oxide. A method of making a proppant is also provided, with that method comprising melting at least one metal oxide in an electrical arc furnace, pouring the molten metal oxide to create a pour stream, and separating the pour stream to form at least one electrofused pellet. A method of fracturing subterranean formations is also provided, with that method comprising injecting a fluid containing at least one electrofused pellet.</p>
