Embodiment 1
[0018] Weigh 5g of titanium diboride particles with a particle size of 5 μm in a 100mL beaker, add 10mL of acetone, stir for 5min, filter with suction, put the titanium diboride particles in a 100mL beaker, add 6mol L -1 10mL of hydrochloric acid solution, soaked for 0.2h, filtered with suction, washed with water until neutral, and dried in an oven at 50°C for 5h. Weigh 1 g of lanthanum oxide particles with a particle size of 5 μm in a 50 mL beaker, add 5 mL of acetone, stir for 5 min, and filter with suction. Add 250g of nickel sulfate, 30g of nickel chloride, and 25g of boric acid into a 2L beaker, add 985mL of water to dissolve to form a transparent nickel sulfate-nickel chloride-boric acid mixture, adjust the pH of the solution to 3 with sodium bicarbonate solution, and transfer it to 1L In a volumetric flask, dilute to the mark with water. Put the titanium diboride and lanthanum oxide particles treated above in a mortar, add 0.01g of cetyltrimethylammonium bromide surfac...
