- •
U3Si2 fabricated from elemental uranium and silicon through arc melting.
- •
Homogeneity of the silicides assessed through densitometry, XRD, SEM and EDS, chemical etching and optical microscopy.
- •
UN powder fabricated using hydriding-nitriding method.
- •
No phase transformations detected when sintering using silicide particle sizes less than UN particle size.
- •
