Some properties of a lead vanado-iodoapatite Pb10(VO4)6I2

摘要: A lead vanado-iodoapatite Pb 10 (VO 4 ) 6 I 2 was synthesized as a potential waste form to immobilize radioactive iodine and some thermal, mechanical chemical properties were measured. Thermogravimetry-differential thermal analysis (TG-DTA) showed that the apatite stable up about 800 K. The conductivity of hot-pressed sample, with theoretical density 82%, increased gradually increasing temperature from 0.65 W/m.K at room 0.78 523 micro-Vickers hardness Young's modulus lower than those typical glass form. leaching rate for two orders magnitude higher an AgI Despite high (compared embedded in glass), stability K acceptable this suggest it will be good when suitable matrix material.
