In the conventional sintering of UO2, the sintering atmosphere is hydrogen in all zones of the furnace and the sintering temperature is 1700 ºC.
In the low temperature sintering process, the sintering is carried out in the mildly oxidizing carbon dioxide atmosphere at 1200 ºC.
The low temperature sintering furnace has another zone at 1200 ºC with hydrogen for bringing down the O/U to stoichiometric level.
