Abstract
An abrasive article including a body including a bond material having an inorganic material including a ceramic, abrasive agglomerates including silicon carbide contained within the bond material, and a permeability of at least 60.
Claims16
An abrasive article, comprising a body including:
- from 3 vol % to 20 vol % for a total volume of the body of a bond material comprising an inorganic material comprising a ceramic, wherein the bond material comprises:
- from 30 wt % to 60 wt % of silica (SiO2) for a total weight of the bond material;
- from 0.5 wt % to 15 wt % sodium oxide (Na2O) for the total weight of the bond material;
- zircon;
- and
- less than 1 wt % of potassium oxide (K2O) for the total weight of the bond material;
- from 25 vol % to 55 vol % abrasive agglomerates for the total volume of the body, wherein the abrasive agglomerates comprise abrasive particles and are contained within the bond material, wherein the abrasive particles consist of silicon carbide abrasive particles;
- not greater than 4.5 vol % for the total volume of the body of a ceramic pore former;
- and
- a permeability of at least 60.
