“…The main chemical composition of the mainstream ceramic proppant after sintering is Al 2 O 3 and SiO 2 , and the main phases are corundum (Al 2 O 3 ) and mullite (3Al 2 O 3 ·2SiO 2 ) 23,24 . Corundum and mullite crystals have high strength in nature and can offer satisfactory strength to ceramic proppants 25–27 . Mullite crystals are rod‐shaped and interspersed in corundum crystals to reduce the density and enhance the toughness of ceramic proppants 28 .…”

Ceramic proppants are preferred in hydraulic fracturing because of their high strength, good sphericity, and excellent acid corrosion resistance. Bauxite is the main raw material of ceramic proppants, but with the increasing depletion of bauxite resources, substitutes for bauxite need to be sought. Coal gangue is a solid waste that is rich in SiO 2 and Al 2 O 3 , making it a potential substitute for the preparation of ceramic proppants. The use of coal gangue to prepare ceramic proppants can reduce the cost of ceramic proppants and benefit environmental protection. Studies on using coal gangue to prepare ceramic proppants have been conducted and achieved progress, but further improvement can still be obtained.Here, the basic principle, progress, and prospects of coal gangue ceramic proppants are reviewed. First, coal gangue ceramic proppants are divided into two categories, namely, proppants prepared using coal gangue as an auxiliary material and proppants prepared using coal gangue as the main material. Second, the progress of research of coal gangue ceramic proppants is summarized from the perspective of additives, and the influence of different kinds of additives on the sintering temperature and performance of proppants is discussed. Lastly, the future prospects of coal gangue ceramic proppants are presented.
