Latest Patents

Zhang's latest patents include a method for preparing high-melting-point metal powder through multi-stage deep reduction. This invention involves mixing dried high-melting-point metal oxide powder with magnesium powder to initiate a self-propagating reaction. The process continues with leaching the intermediate product with hydrochloric acid to obtain a low-valence oxide MeO precursor. The precursor is then mixed with calcium powder, pressed, and subjected to vacuum reduction at high temperatures to yield high-melting-point metal powder.

Another notable patent is the method for preparing ferrovanadium alloys based on aluminothermic self-propagating gradient reduction and slag washing refining. This method includes several steps, such as performing aluminothermic self-propagating gradient reduction, heat preserving, and smelting to separate alumina-based slag from alloy melt. The process also involves refining the alloy melt through jetting and stirring, ultimately cooling it to room temperature to obtain ferrovanadium alloys.
