摘要：

Pyrohafnates of rare-earth elements have potential applications as neutron absorber materials in nuclear technology. These compounds have the general formula R2Hf2O7, where R represents the rare-earth element. The percentage thermal expansion of lanthanum, europium and gadolinium pyrohafnates has been measured from room temperature to 1473 K by X-ray powder diffractometry. © 1990.
