Abstract
Various embodiments disclosed relate to pore inducers and porous abrasive forms made using the same. In various embodiments, the present invention provides a method of forming a porous abrasive form including heating an abrasive composition including pore inducers to form the porous abrasive form. During the heating the pore inducers in the porous abrasive form reduce in volume to form induced pores in the porous abrasive form.
Claims8
A method of forming a porous abrasive form, the method comprising:
- heating an abrasive composition to form the porous abrasive form, the abrasive composition comprising a plurality of pore inducers, the plurality of pore inducers having a pore inducer composition that comprises gamma-pyrone, the plurality of pore inducers each having a 3D geometric shape and a size, wherein the plurality of pore inducers have the same 3D geometric shape and size;
- and
- wherein during the heating the pore inducers in the porous abrasive form reduce in volume to form induced pores in the porous abrasive form, wherein the induced pores substantially correspond in shape and location to that of the pore inducers in the abrasive composition prior to the heating.
