Preparation of UO2/TiO2 composite ceramic fuel by sol gel-press forming method

This paper studies the preparation of UO2/TiO2 composite ceramic fuel through sol gel-press forming. The research shows that at 1200–1300 °C, UO2/TiO2 composite ceramic grains are small, uniform and compact. Among them, UO2–0.5 wt%TiO2 has the highest density and good mechanical strength at 1250 °C.
