The chemically activated CMP slurry compositions and methods for using a slurry to polish a substrate having a silicon carbide surface are provided. In this method, the surface of the silicon carbide is in contact with the CMP slurry composition, the CMP slurry composition, and i) a plurality of particles having a liquid carrier ii) at least a soft-surface area, it may optionally include an oxidizing agent. Here, the soft surface region comprises a transition metal compound to provide a Mohs hardness of 6 or less. The oxidant may also include a transition metal. The slurry is moved relative to the surface containing said silicon carbide, at least a portion of the silicon carbide-containing surface is removed.
