BS>Cermets of UO/sub 2/ and Si are described which offer improved thermal shock and oxidation resistance. In an example, Si powder (density 2.33) and UO/sub 2/ powder (density 10.4) were mixed and col d compacted at 1000 deg C, whereupon the heated in the die at this pressure to 1000 deg C, whereupon the pressure was raised to 2000 psi and the temperature to 1450 deg C and these conditions maintained for 10 minutes. These samples had transverse rupture strength of 4 to 6 tsi after quenching from 400 deg C compared to 0.5 tsi for UO/ sub 2/ only. (T.R.H.)
