Abstract

Abstract

Lithium oxide (Li₂O) is one of the best tritium breeding materials. A new wet process, freeze drying method, was used to prepare Li₂O pebbles by Li₂CO₃ powder. Preliminary fabrication tests including freezing, calcination and decomposition were carried out to investigate the fabrication technique parameter of Li₂O pebbles. It is suggested that Li₂O pebbles can be fabricated by the decomposition of Li₂CO₃ pebbles at 720 ℃, which were prepared by freeze drying method and calcinated at 650 ℃. Li₂O pebbles sintered at 900 ℃ have a diameter of 0.8 mm, grain size of 9 μm, density of 69.5% theoretical density and porous structure.
