چکیده

In the given ga, v–zrsio4 nanoparticles were prepared via a microwave– mediated polyol synthetic method. after microwave heating the stable and uniform suspensions was obtained. finally, by firing in 1100 ◦c the completely crystalline and pure zircon nanoparticles achieved. the zircon fraction αzr in all crystalline species is estimated as a function of diffraction peak intensity. according to the calculations, when increasing the microwave power from 300 w to 900 w, the zircon formation ratio αzr is the highest (80%). the formation of zircon, which is positively correlated with microwave power, increases rapidly during the process from 300 w to 600 w. taking into account the influence of two aspects (microwave power and time of irradiation), 900 w / 60 s turned out to be the best microwave heating condition. therefore, zrsio4 can be fully synthesized at lower than the previous studies with the same composition, indicating that the microwave-assisted polyol method can effectively reduce the formation temperature of zrsio4. these results confirm that microwave power affects the size of v-zrsio4 nanoparticles. the average particle size of nanoparticles decreases with decreasing microwave power.

Abstract
|
In the given GA, V–ZrSiO4 nanoparticles were prepared via a microwave– mediated polyol synthetic method. After microwave heating the stable and uniform suspensions was obtained. Finally, by firing in 1100 ◦C the completely crystalline and pure zircon nanoparticles achieved. The zircon fraction αZR in all crystalline species is estimated as a function of diffraction peak intensity. According to the calculations, when increasing the microwave power from 300 W to 900 W, the zircon formation ratio αZR is the highest (80%). The formation of zircon, which is positively correlated with microwave power, increases rapidly during the process from 300 W to 600 W. Taking into account the influence of two aspects (microwave power and time of irradiation), 900 W / 60 s turned out to be the best microwave heating condition. Therefore, ZrSiO4 can be fully synthesized at lower than the previous studies with the same composition, indicating that the microwave-assisted polyol method can effectively reduce the formation temperature of ZrSiO4. These results confirm that microwave power affects the size of V-ZrSiO4 nanoparticles. The average particle size of nanoparticles decreases with decreasing microwave power.
