Figure 12.1 Schematic diagram of a tube furnace used for controlled atmosphere sintering.

The individual layers are aligned and laminated under heat and pressure to form a monolithic structure in preparation for firing. The structure is heated to approximately 600°C to remove the organic materials. Carbon residue is removed by heating to approximately 1200°C in a wet hydrogen atmosphere. Sintering and densification take place at approximately 1600°C. 

Nanotechnology and vacuum or atmosphere sintering approaches make the fribrication of highly transparent ceramic materials possible. To prepare transparent ceramies, a strict control...
