Mixed hydroxides, thermal reactions

AFBC ashes exhibit hydraulic properties. The main reaction products are a C-S-H phase and ettiingite formed in a reaction of the thermally activated clay minerals with the present free lime, calcium sulfate, and mixing water. PFBC ashes are similarly reactive however, calcium oxide or calcium hydroxide must be added to the system to compensate for the lack of sufficient amounts of free lime in the ash. [Pg.138]

Surface oxidation behaviour of uranium carbide (UC) in air was studied. It is seen that formation of uranium oxide/hydroxide and free carbon can happen as a consequence of the reaction between UC and oxygen/moisture. It is noted that the sutl ce of the oxidised UC consists of a top contamination layer of adsorbed oxygen/moisture, followed by a layer containing uranium oxide, uranium hydroxide and free carbon and then grain boundary oxide and finally bulk UC. The bahaviour of sintered and arc-melted samples is found to be similar. Thermal conductivity of mixed oxide fuel (45%U - 55%Pu) was measured using laser flash technique covering a temperature range from 700 to 1550 K. [Pg.131]
