the further study indicates that the monoclinic phase of cds can firstly be transformed into the cubic phase and then into the hexagonal phase when annealed at temperatures larger than 350℃.
研究表明:当温度高于350℃,硫化镉单斜相将首先转变为立方相,然后变成六方相。
xrd pattern shows that the formation of hexagonal phase of la(oh)3, indicating that the hydration process is very quickly.
xrd衍射图显示在短时间内可以得到六方相氢氧化镧,表明其水化过程是相当快的。
the later corresponded to the transition from orthorhombic phase to hexagonal phase and the melting behavior of hexagonal phase separately.
后者则分别对应于正交晶相向六方晶相的转变和六方晶相的熔融。
however, the selected area's electron diffraction shows that it has both cubic and hexagonal phase structures corresponding to different shapes. this is attributed to the isomeric state of zns.
