Orthorhombic Molybdenum Trioxide Whiskers by Vapor Transport Method

Orthorhombic Molybdenum Trioxide Whiskers by Vapor Transport Method

Orthorhombic MoO3 whiskers have been grown by using vapor transport method. High-quality, transparent and colorless MoO3 plate-like whiskers are obtained inside alumina furnace tube with high aspect ratio of 20-30 for the growth time of 1 h. The length and the width of whiskers are directly proporti...
