Examples
Example Embodiment
[0022] Example 1:
[0023] Mix 60 parts of alumina, 48 parts of silicon oxide, 16 parts of graphite powder and 8 parts of lanthanide rare earths, ball mill them in an aqueous solution, and then inject them into the model to form, dry and then enter the kiln to be fired at about 1500°C. A ceramic diaphragm electrolytic cell with a porosity of 32% and an average pore diameter of 0.9μm.
Example Embodiment
[0024] Example 2:
[0025] Mix 50 parts of alumina, 30 parts of silicon oxide, 5 parts of rare earth powder and 5 parts of lanthanide rare earths, ball mill them uniformly in an aqueous solution, and then inject them into the mold to form, dry and enter the kiln to be fired at about 1000°C. A ceramic diaphragm electrolytic cell with a porosity of 11% and an average pore diameter of 0.35μm.
Example Embodiment
[0026] Example 3:
[0027] Mix 75 parts of aluminum oxide, 60 parts of silicon oxide, 20 parts of carboxymethyl cellulose and 15 parts of lanthanide rare earths, ball mill them in an aqueous solution, and then inject them into the mold to form, after drying, enter the kiln and burn at about 1600°C. A ceramic diaphragm electrolytic cell with a porosity of 40% and an average pore diameter of 1.5 μm is obtained.
