The ‘green body’ compact is now loaded into the specially designed high-temperature furnace. The compact is heated to 1800°C in an atmosphere of pure nitrogen. In this step, the fine, thoroughly blended powder grains react with the nitrogen from the furnace atmosphere and coalesce to form a solid material. This process of reaction sintering allows nitrogen from the furnace atmosphere to be incorporated into the chemical makeup of the O-Sialon.
