Comparison of the effects of MoSi2 and CrSi2 on sintering and properties of titanium diboride (TiB2) [PDF]

Processing and Application of Ceramics, 2023
Titanium diboride (TiB2) is a typical material classified as structural ceramics. However, sintering of TiB2 ceramics is difficult mainly because of a significant fraction of covalent bonds in the structure. In order to obtain dense TiB2 ceramics various
