A molten aluminium droplet of 99.994 mass% fell onto a water-cooled copper mold. The mass of the molten droplet was 0.5g. Temperature of the molten droplet was 973K, 1023K or 1073K The falling height was 50, 70 or 90mm. The shape of solidified droplet is classified into three types. One is the specimen with a convex surface (TypeA). Another is the specimen with a concave surface (TypeB). The third is neither TypeA nor TypeB (TypeM). The height of the solidified droplet increased as increasing the casting temperature. The periphery length and the area of the bottom of the solidified droplet decreased as increasing the casting temperature. The upper part of the droplet vibrated during solidification. The solidification mechanism of the molten droplet was clarified.
