Embodiment 1
[0025] The preparation of embodiment 1 cerium-zirconium composite oxide
[0026] Take cerium nitrate and zirconium nitrate, mix them at a molar ratio of 3:1, add water at a solid-to-liquid ratio of 0.08 g / mL, stir until they are completely dissolved, and add 15% by mass ammonia water under constant stirring until the pH of the solution is 10; Stand still for 2 hours, filter, and wash the filter residue with water until the pH of the filtrate is 7-8; dry the washed filter residue at a temperature of 120°C for 12 hours; things.
Embodiment 2
[0027] The preparation of embodiment 2 bulk far-infrared ceramic materials
[0028]In parts by weight, the bulk far-infrared ceramic material of the embodiment of the present invention consists of the following components: 1 part of tourmaline, 25 parts of silicon dioxide, 7 parts of titanium dioxide, and the cerium-zirconium composite oxide prepared in Example 1 12 parts, 6 parts of α-alumina, 3 parts of silicon carbide, 0.5 part of tantalum carbide, 0.05 part of titanium aluminum nitride carbide, 10 parts of calcium carbonate and 4 parts of polyvinyl alcohol aqueous solution with a mass fraction of 3%.
