Abrasive particles comprise an alpha-alumina crystalline phase and from 0.25 to 20 percent by weight of a beta-alumina crystalline phase, based on the total weight of the alpha-alumina crystalline phase and the beta-alumina crystalline phase combined. The beta-alumina crystalline phase is represented by the empirical formula (X)(Q)Al10O17, wherein: X is selected from the group consisting of Sr, Ca, and Ba; and Q is selected from the group consisting of Mg, Co, Ni, and Zn. Methods of making and using the abrasive articles and abrasive articles are also disclosed.
