Crystal Habits include the cube, octahedron and pyritohedron (a dodecahedron with pentagonal faces) and crystals with combinations of these forms.

晶形态常呈立、角十二面，较少呈八面，或集合晶簇。

The synthesis of fluorine substituted saponite was explored and suceeded under mild temperature hydrothermally.Microwave-hydrothermal synthesis of sapontie was performed first time.

对于层状材料的微波水热快速合成研究也进行了首次探，发现可以在可接受的合成条件下得到具有三八面结构的皂石。
