Zahteve za surovine so naslednje:
(1) Praženje molibdena zahteva S<0.10%, Cu<0.6%, and Pb<0.5%. The actual ingredients are: Mo48.5%~52%, S0.04%~0.07%, P0.01%~0.02%, Cu0.1%~0.5%, Pb0.2%~0.5%, FeO3%~5%, SiO28%~14%, CaO2%~4.5%. 5% to 10% of the total molybdenum is in the form of MoO2, which should be considered when calculating the reaction heat. The particle size is <15mm, of which >10 mm predstavlja manj kot 10 % in<2mm accounts for about 60%. (2) Ferrosilicon powder contains Si75%~77%; the particle size is <1mm.

(3) Aluminum particles contain Al>90 % in Cu<0.1%; the particle size is <3mm, and the part <0.5mm shall not exceed 30%.
(4) Iron ore contains Fe>65%, S<0.05%, P<0.05%, C<0.30%; particle size<1mm. Iron oxide scale or iron concentrate can be used instead.
(5) Jekleni ostanki so navadni ostanki ogljikovega jekla, dolžina kodra pa je<50mm.
(6) Fluorite contains CaF2>90 % Velikost delca<3mm.

(7) Saltpeter contains NaNO3>90 % Vse surovine morajo biti temeljito posušene in ne smejo vsebovati vlage, da se prepreči brizganje in nesreče med postopkom taljenja. Surovine se natančno stehtajo glede na izračunani delež, dajo v mešalnik in enakomerno premešajo, nato dajo v talilno peč in talijo z metodo zgornjega vžiga.
