Example Embodiment
[0024] The preparation method of the high infrared emissivity ceramic of the embodiment of the present invention includes:
[0025] Step 1: Mix the ingredients
[0026] The magnesium-rich metallurgical nickel slag is ball milled for 3-5h at a speed of 300-500 rpm. After ball milling, 30-40% of magnesium-rich metallurgical nickel slag and 30-35% of Al 2 O 3 , 25-32% SiO 2 , 3-7% of Y 2 O 3 And 2-5% K 2 CO 3 Mix to obtain embryonic raw materials.
[0027] Further, preferably, 32-35% of magnesium-rich metallurgical nickel slag and 30.2-30.5% of Al 2 O 3 , 28.7-30.3% SiO 2 , 3-6% Y 2 O 3 And 3-4% K 2 CO 3 mixing.
[0028] The preparation method of the high infrared emissivity ceramics of the embodiment of the present invention uses magnesium-rich metallurgical nickel slag as a raw material, and can utilize the inherent iron, manganese, nickel and other elements in the magnesium-rich metallurgical nickel slag without adding transition metal oxides , And the SiO contained in the nickel sla...
