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.
Claims9
A method of forming a porous vitreous abrasive form, the method comprising:
- molding a pore inducer staring material composition to form a plurality of hollow glass filler pore inducers with a 3D geometric shape and a size, wherein each of the plurality of pore inducers have the same 3D geometric shape and size;
- heating an abrasive composition comprising pore inducers comprising the molded hollow glass filler pore inducers, to form the porous vitreous abrasive form;
- and
- wherein during the heating the pore inducers in the porous vitreous abrasive form reduce in volume to form induced pores in the porous vitreous abrasive form, wherein the induced pores comprise a shape similar to the 3D geometric shape.
