Green density variations in relation to colloidal packing in SiC/Si{sub 3}N{sub 4} composites
- Michigan State Univ., East Lansing, MI (United States)
Composites of SiC/Si{sub 3}N{sub 4}, were produced using the processing conditions established in Stable Suspension{copyright}. This program utilizes Hogg, Healy and Furstenau`s modifications to DLVO theory to predict the stability conditions for composite suspensions. By altering the suspension pH, the conditions for SiC to SiC and Si{sub 3}N{sub 4} to Si{sub 3}N{sub 4} (homostability) attractions and the SiC to Si{sub 3}N{sub 4} (heterostability) attractions have been manipulated to obtain different green packing structures. The degree of homo- versus heterostability was controlled and the distribution of the Si{sub 3}N{sub 4} within the SiC determined. Additionally, this distribution was related to the green density of the composite. Results from density measurements versus the degree of homo- and heterocoagulation are presented along with SEM photomicrographs indicating the microstructural packing in the green body.
