Abstract:A slurry with high dispersibility is crucial for slip casting technology. The weakly acidic SiC powder with high dispersibility was prepared with polyacrylic acid pretreated by the sodium hydroxide (adjusted pH = 5). The pretreated polyacrylic acid can be effectively adsorbed on the surface of SiC powder, and its utilization efficiency (37%) was better than the unpretreated one (21%). The modified SiC powder with pH = 6 was obtained by polyacrylic acid modification, and the maximum solid content was 61.2 Vol%.… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
