By cooling slowly a homogeneous solution of La, B and Al from about 1200℃, single crystals of lanthanum hexaboride (LaB_6) were precipitated, and their lattice constant, purity and growh-orientations were investigated. The products are needle-like crystals with a rectangular cross section, thin plate-like crystals and cubical crystals. The LaB_6 crystal has the lattice constant 4.1564Å and contains impurities of less than 0.01 wt%. More needle-like crystals with [110] growth direction tend to be formed than any crystals with other shapes. For the typical needle-like crystals, the crystal thickness depends on the cooling rate. The average size is 0.1 to 0.5 mm square in cross section and about 5 mm in length.
