Study on the Microstructure and Morphology of Sintering Process of SiC-TiB2 Composite

摘要

This research employs pressureless sintering process to study the impact of different amount of titanium diboride on the performance of silicon carbide-titanium diboride composite.Results show that:no new phase was produced,and the whole process is a solid-phases sintering process.In this experiment,it has the smallest relative density and loss on ignition and porosity,and highest degree of densification of the silicon carbide-titanium diboride composite ceramics sintered body when the titanium diboride content is 50g,and the quality of SiC and TiB2 ratio is 1∶1.
