1. A method of making an abrasive article comprising:
forming a mixture comprising abrasive particles, a bond precursor material including an inorganic material and a gelling agent, wherein the gelling agent is selected from the group consisting of agar, agarose, xanthan gum, carboxy methyl cellulose, gellan gum, carrageenan gum, guar gum, tara gum, cellulose gum, locust bean gum, or any combination thereof, and wherein the abrasive particles have an average particle size of at least 40 microns;
adding a cationic agent to the mixture and forming a gel, wherein the cationic agent comprises an inorganic material that cross-links with the gelling agent, and wherein adding the cationic agent initiates crosslinking and formation of the gel;
forming a green body from the gel; and
forming a bonded abrasive body from the green body.
