Vanadium alloy reduction smelting reducing agent for smelting ferrovanadium alloy, which is used in infrastructure construction of oil transportation/gas pipeline, building, bridge and rail, is graphene load silicon-zinc-aluminum alloy.

UNANNOUNCED I, ZHANG C

Powdery vanadium-nitrogen alloy useful in manufacturing process of steel, toughness, ductility and thermal fatigue resistance, comprises vanadium compound, carbonaceous reducing agent, binder, water and iron powder, where binder is polyester resin, hydroxy acrylic resin and polycarbonate diol.

UNANNOUNCED I, ZHANG C

Preparing high quality and low cost vanadium nitride iron alloy comprises e.g. adding vanadium source compound, iron source compound and reducing agent into de-ionized water, stirring to obtain mixed solution, and adding citric acid.

ZHANG C

Preparation of ferro-vanadium nitride alloy involves adding e.g. vanadium/iron source compounds to deionized water, stirring, adding citric acid, ultrasonically stirring, drying, grinding, adding graphene to solid powder, and calcining.
