Abrasive grains – usually aluminum oxide or silicon carbide
Bonding agent – usually a resin bond
Spacing of grains within the bond – determine porosity and strength
What is melting vs. Sintering?
When processing minerals in a furnace, materials can either be melted or sintered. When materials are melted during the production process the minerals go from a solid state, to a liquid state, then is re-solidified during the cooling process
