摘要：

A powder mixture compact composed of MgO and Cr2O3 was embedded in carbon powder in an alumina crucible which is covered with a lid with a hole. On heating to above 1600 degrees C, MgCr2O4 whiskers were grown on the compact. The whiskers grown at 1700 degrees C for 2 h were several mm to about 6 mm in length and several mu m to about 220 mu m in diameter. Most of them grew in the direction of the a-axis. The whiskers apparently grew by the vapor-solid (VS) mechanism.
