Embodiment 1
[0018] Weigh 0.025 moles of ferric nitrate, 0.075 moles of glycine, and 0.05 moles of carbon source, dissolve various raw materials in distilled water to prepare a solution, and place the solution on a temperature-controllable electric furnace for heating. After the solution undergoes a series of reactions such as volatilization, concentration, and decomposition, the precursor powder is obtained, and the precursor powder is reacted at 550°C under nitrogen atmosphere for 2 hours to obtain nano-iron carbide powder.
Embodiment 2
[0020] Weigh 0.025 moles of ferric nitrate, 0.025 moles of glycine, and 0.05 moles of carbon source, dissolve various raw materials in distilled water to prepare a solution, and place the solution on a temperature-controllable electric furnace for heating. After the solution undergoes a series of reactions such as volatilization, concentration, and decomposition, the precursor powder is obtained, and the precursor powder is reacted at 750 ° C for 1 hour under the conditions of argon atmosphere to obtain nano-iron carbide powder.
Embodiment 3
[0022] Weigh 0.025 mol of ferric nitrate, 0.1 mol of glycine, and 0.125 mol of carbon source and dissolve them in distilled water to prepare a solution, and heat the solution on a temperature-controllable electric furnace. The solution reacts after undergoing a series of processes such as volatilization, concentration, and decomposition to obtain a precursor powder. The precursor powder is reacted in a furnace at 700°C and nitrogen atmosphere for 1.5 hours to obtain nano-iron carbide powder.
