<p>Bonding of sintered sol-gel aluminous abrasive grits, comprising sub-micron sized alpha alumina crystals, in vitrified (ceramic) wheels results in abrasive performance superior to premium grade fused alumina in grinding toolsteels. Viscosity of the bond and/or temperature of firing must be controlled to avoid reaction between the bond and the abrasive.</p> |
