It is shown for the first time that aluminum oxide whiskers with a porous structure grow on ceramic made from the lead-zinc ore beneficiation wastes with the addition of granular aluminum. The morphology of the grown whiskers was studied. It is shown that a whisker has the shape of a cone with a metal drop on its vertex. X-ray phase and electron-microscopic studies with mapping of the whiskers were performed. The complex composition of a metal drop on the vertex of a whisker is noted. A possible mechanism of their formation is discussed.

用铅锌矿选矿废料制备的陶瓷表面生产α-Al2 O 3晶须

首次表明，在添加了粒状铝的情况下，由铅锌矿选矿废物制成的陶瓷上会生长具有多孔结构的氧化铝晶须。研究了生长的晶须的形态。结果表明，晶须具有圆锥形状，其顶点上有金属滴。进行了X射线相和电子显微镜研究，并绘制了晶须图。注意到晶须顶点上金属滴的复杂组成。讨论了其形成的可能机制。
