Hollow Cr 3 C 2 polycrystals with Cr 2 O 3 were grown by heating a powder compact of MgO and Cr 2 O 3 in carbon powder at 1600° to 1700 deg; C. They were classified into two types: a stick and a thick plate. After being heated at 1700 deg; C for 2 h, the polycrystals grown as the thick‐plate type were several micrometers to about 3 mm in length, whereas the polycrystals grown as the stick type were several micrometers to about 1 mm in length. They were considered to be grown by a vapor‐solid mechanism .
