It is shown for the first time that filamentary & # 171; whiskers & # 187; aluminum oxide with a porous structure. The morphology of the grown & # 171; whiskers & # 187; was studied. It is shown that & # 171; mustache & # 187; has the shape of a cone with a drop of metal at its top. X-ray phase and electron microscopic studies with mapping of whiskers have been carried out. There is a complex composition of a drop of metal at the top of the & # 171; whisker & # 187;. A possible mechanism of their formation is discussed.
