【 摘 要 】

We found some layered phases in the composite prepared by reactive hot pressing at 1800°C for 30 mins, using ZrC and LnB6(Ln = La, Ce, and Gd) as raw materials. The layered phases are related to rare-earth metal borocarbides, but they are relatively and chemically stable in moisture environment. XRD patterns of these layered phases cannot be identified far away, indicating that the layered phases are possibly some new compounds.
