在室温下，使用高达68 GPA的钻石砧室进行了对CD的原位X射线衍射研究，发现CDS型CDS在约56 GPA时转换为新的高压多晶型物。新的高压多晶型物的X射线衍射模式通过最低的温度KCN结构类型成功地索引了岩石结构将转换计算出约0.8％。
High‐pressure in situ x‐ray diffraction study on CdS and BP was performed using a diamond anvil cell up to 68 GPa at room temperature. The rocksalt structure type CdS was found to transform to a new high‐pressure polymorph at about 56 GPa. X‐ray diffraction pattern of the new high‐pressure polymorph was successfully indexed by the lowest temperature KCN structure type with the distorted rocksalt structure. Volume change accompanied with the transformation was calculated to be about 0.8%. This small volume change may be responsible to the undetectable change in refractive index of CdS at the transformation. No phase transformation was observed on BP: the zincblende structure is stable up to 68 GPa.
