Preparation method of low-temperature sintered alumina ceramic abrasive
The invention relates to the technical field of aluminum oxide ceramic abrasives, and discloses a preparation method of a low-temperature sintered aluminum oxide ceramic abrasive, which comprises the following steps: (1) preparing an acid-base solution, and forming an aluminum oxide seed crystal by using the solution and an aluminum oxide ore body, (2) evaporating and dehydrating sol to form gel, and (3) drying the gel to obtain the low-temperature sintered aluminum oxide ceramic abrasive. The preparation method of the low-temperature sintered aluminum oxide ceramic abrasive comprises the following steps: calcining aluminum hydroxide in a calcining furnace at 1130-1320 DEG C for 23-44 minutes to obtain aluminum oxide, mixing and calcining with an additive, and calcining the aluminum oxide at 850-970 DEG C for 3-4 hours by using the additive in equal proportion to obtain the low-temperature sintered aluminum oxide ceramic abrasive. The dried aluminum oxide powder is matched with a sintering aid for low-temperature sintering, the coarse material of the aluminum oxide powder is subjected to ball milling by utilizing a lattice type ball mill to form crushed aluminum oxide, and the crushed aluminum oxide is screened, so that the aluminum oxide abrasive is obtained, and the situation that a large amount of electric power is consumed by adopting an electric melting process is avoided.
