Titanium dioxide ceramic material prepared by sol-gel method
The invention relates to a titanium dioxide ceramic material prepared by a sol-gel method. Rare earth elements cerium and yttrium are doped on the surface of titanium dioxide porous ceramic by an ion implantation method. Essentially, ion implantation of rare earth elements can play a role in hole sealing, after ion implantation, a TiO2-Ce-Y composite ceramic material is formed on the surface of titanium dioxide ceramic or a near-surface area, and the corrosion resistance of porous titanium dioxide is improved. It is worthy of noting that the implantation amount of rare earth elements needs to be controlled within a reasonable range, if the implantation amount of the rare earth elements is too large, a Ce-Y film is formed on the surface of titanium dioxide ceramic, and if the implantation amount of the rare earth elements is too small, a proper hole sealing effect cannot be achieved, and the situations are not beneficial to improvement of the corrosion resistance of the porous titanium dioxide ceramic material.
一种溶胶‑凝胶法制备而得的二氧化钛陶瓷材料，通过离子注入法在二氧化钛多孔陶瓷表面掺入稀土元素铈和钇。本质上，离子注入稀土元素可以起到封孔作用，离子注入后，在二氧化钛陶瓷表面或近表面区域形成了TiO2‑Ce‑Y复合陶瓷材料，提高了多孔二氧化钛的耐腐蚀性能。值得注意的是，稀土元素的注入量需控制在合理的范围，稀土元素注入量过多，则在二氧化钛陶瓷表面形成了Ce‑Y薄膜，稀土元素注入量过少，则无法起到合适的封孔效果，这都不利于多孔二氧化钛陶瓷材料耐腐蚀性能的提高。
