三方晶系,arh=0.5421nm,α=55。17';Z=2。ah=0.5039nm,ch=1.3760nm;Z=6。刚玉型结构。成分中有Ti的替代时,晶胞体积将增大;而Al的替代则使晶胞体积减小。复三方偏三角面体晶类,D3d-3m(L33L23PC)。完好晶体较少见。常见单形:平行双面c,六方柱a,菱面体r、u、e,六方双锥n。在晶面上有三组平行于和交棱方向的条纹、三角形凹坑或生长锥等晶面花纹。依为聚片双晶,依(0001)为穿插双晶或接触双晶。常呈显晶质板状、鳞片状、粒状和隐晶质致密块状、鲕状、豆状、肾状、粉末状等集合体形态。
The three party system, arh=0.5421nm, alpha =55. 17'; Z=2. Ah=0.5039nm, ch=1.3760nm; Z=6. Corundum type structure. A substitution of Ti components, the unit cell volume will increase; and the substitution of Al makes the unit cell volume decreased. The resumption of the three party scalenohedral crystal class, D3d-3m (L33L23PC). A rare intact crystal. The common simplex: parallel double C, six square column a, rhombohedral R, u, e, n six bipyramide. There are three groups of parallel to the direction of the stripe, and the intersection edge triangular pits or growth cone grained surface pattern on the crystal surface. According to the polysynthetic twin, according to (0001) as a twin or contact twin interspersed. Chang Chengxian crystal plate, flake, granular and cryptocrystalline dense block, oolitic, lenticular, reniform, powder and other aggregate morphology.
