Uranium karbida

Uranium karbida, sebuah karbida dari uranium, adalah material keramik keras tahan api. Muncul dalam beberapa stoikiometri (U C_x), seperti uranium metanida (UC, nomor CAS 12070-09-6), uranium sesquicarbide (U₂C₃, nomor CAS 12076-62-9),^[1] dan uranium asetilida (UC₂, nomor CAS 12071-33-9).^[2]^[3]

Seperti uranium dioksida dan beberapa senyawa uranium lainnya, uranium karbida dapat digunakan sebagai bahan bakar nuklir untuk reaktor nuklir, biasanya dalam bentuk pelet atau tablet. Bahan bakar uranium karbida digunakan dalam desain akhir roket termal nuklir.

Pelet uranium karbida digunakan sebagai kernel bahan bakar untuk reaktor unggun kerikil versi AS; versi Jerman menggunakan uranium dioksida sebagai gantinya.

Sebagai bahan bakar nuklir, uranium karbida dapat digunakan sendiri, atau dicampur dengan plutonium karbida (PuC and Pu₂C₃). Campuran ini juga diberi label sebagai uranium-plutonium karbida ( (U,Pu)C ).

Karbida uranium juga merupakan bahan target populer untuk akselerator partikel.

Sintesis amonia dari nitrogen dan hidrogen kadang-kadang dilakukan dengan adanya uranium karbida yang bertindak sebagai katalis.
