  • At room temperature and up to 13 GPa, in situ energy dispersive X-ray diffraction measurements for a natural cassiterite, collected from Gejiu tin deposits, Yunnan, were performed by using diamond anvil cell instrument with synchrotron radiation at BSRF. The results show that cassiterite is stable up to 13 GPa and its parameters of unit-cell decrease with increasing pressure. On the other hand, the parameters of unit-cell we calculated are bigger than these of former experiments with synthetical cassiterite. According to Birch equation of state, KT(0)=228 GPa. For natural cassiterite crystal, it is believed that Zr replacing to Sn may be the reason for expansion of unit-cell.
