Conventional sintering polycrystalline ceramics

Conventional sintering of ceramic membranes consists of three major steps initial, intermediate, and final sintering. The parameters associated with the stages of sintering for polycrystalline solids [51] are listed in Table 10.2. 

Sintered polycrystalline diamond tools are much more expensive than conventional cemented-carbide or ceramic tools because of the high cost of the processing technique and the finishing methods used. Diamond tools, however, are economical on an overall-cost-per-part basis for certain applications because of long life and increased productivity.
