Sintering of CdO Under Low Applied Stress

A loading dilatometer of novel design was used to study the sintering behavior of CdO powder compacts subjected to stresses between 0 and 0.25 MPa at 973 to 1123 K. Densification and creep occur simultaneously. Although both the volumetric densifcation rate and the uniaxial creep rate show an approximately inverse relation with time, the creep rate increases with stress, whereas the densification rate is independent of stress.
